As some of you may have already noticed I have now completed my first (and likely only) tidy up of the Cactus Trip Diaries – correcting typos and adding extra text and images. It was a highly enjoyable but very time consuming process, completed after I had finished building my presentations for this trip and while I was already showing off what we saw this last winter to a number of BCSS branches in the UK.

The challenge as always remains to use relevant names for the plants. I aim to use names as used in the first edition of the New Cactus Lexicon, but am aware of a numbers of quite dramatic changes that have been the result of the publication of scientific research, particularly DNA studies. The many changes seem to be delaying the preparation and publishing of a second edition of the New Cactus Lexicon, as in addition to name changes, a steady stream of new names for newly discovered cacti have been presented.

I am not quite sure how useful my strategy of using New Cactus Lexicon taxonomy in talks really is when aiming for effective communication with the audience, as many still appear to hang on to Backeberg names from 1966. People just do seem to like change and look for stability in these matters.

I hope that you will enjoy these updates that start from 7 March 2014 and that you’ll join us again around mid October 2014 when we are planning to go back, this time to see Ariocarpus in flower, while the locations found on this last trip are still fresh in our mind.

No images today. No, not an April Fool’s joke, just that with a driving day ahead of us to get to Mexico City, and a first re-packing exercise already completed, the sense of adventure had departed ahead of us. That is until I spotted a ‘Mexican Hat’ shop in Ezequiel Montes, finally a shop that sold sombreros – i.e. ‘Mexican Cowboy hats’ rather than the oversized larger than life hats that I have never seen anyone wear in the streets of Mexico. Why get such a hat on the last day of your trip? Well, to be honest, these plasticised straw hats are not that comfortable when first bought. I’m not quite sure if they need some gentle heat treatment to get them to fit the shape of individual heads – mine seems to be larger than the head of the average Mexican. ‘We know!’ I hear you shout.

This one, and those collected on previous trips will join a gallery of New World (+ South African) head gear on the wall of the Conservatory that was completed in the UK last year and will act as a reminder of the good times enjoyed. I might even wear them when the odd occasion demands that I stand out in a crowd.

With two SatNavs competing for the honour of who could get our destination the nearest (Ian claimed that I had told mine to go to the wrong place, but when I checked the most recent destination, it matched the coordinates that he had given me for the Hotel) we eventually arrived safe and in one piece. Of course, the Gods had to show their displeasure with our leaving by displaying a few thunderbolts, a distant rumble and a light rain just at the time that we had to unpack the car and walk the luggage three blocks to our hotel, through busy shopping streets. No way Jose! I could imagine another flight home with my back ceased up. Fortunately Cliff agreed to driving back to the Hotel, unloading all our luggage, leaving me on guard duty while Ian and he took the car back to the car park.

To distribute the weight of the luggage, I was wearing my bright orange winter sport jacket, leaving other guests no doubt wondering where the Dutchman had put his speed skates. The ensemble was topped off with the newly acquired sombrero. No one dared to take a photo, but I must have looked a picture – including beads of sweat on my forehead.

Tomorrow morning, a taxi collects me at 9:15 for the ride to the airport, from where I catch a flight to Newark (USA) and from there fly on to London Heathrow where Angie will meet me and whisk me straight off to Dover for a Channel Crossing and a drive to Cologne, to visit her Dad who is unwell. That means no Internet contact until I get back to home in the UK on Monday.

It has been a great trip – thanks to Cliff and Ian’s efforts – we must do it again sometime! (Plans exist for a trip to Peru in October 2014, after I get back from the Australian Convention in Brisbane.)

Who said life was dull!?

Today was the last full day’s cactus hunting, we went back towards Bellavista, where we went the first full day to see the southernmost Thelo - T. hastifer. They were in bud then. First I had some stops marked for Ariocarpus kotschoubeyanus ‘elephantidens‘ and at the first (S3133)  it turned out that we had stopped here on that first day to let Ian take some pictures of Yuccas that he liked the look off. Cliff and I didn’t even get out of the car. Today, we ignored Yuccas and put our noses to the ground, to find thousands of Arios!

Our next stop, again for ‘Kots’, turned out to be just 1.3 km away, so we kept that for the way back.
On to a stop first reported 10+ years ago for Turbinicarpus  pseudomacrochele.(S3134) We’ve not had much luck for Turbs ‘proper’ and despite the three of us spread over a hill side for some 90 minutes in the blazing heat, we found none. Cliff was back first to the car – to find the only turb, in flower, right next to the car. We all photographed it from every different angle and moved stones around to make it look like a different plant, but we all know it was just the one. Typical.  Flower colour? You guessed it.

 Much to our surprise, T. hastifer was also here – I thought that it came from just one location, and here it was also in flower, so no need to go back to our original site - quite a long walk from car park to plants.

And back to the Ariostop that we had given a miss (S3135)  on the way up. We were distracted by hundreds of Thelocactus leucacanthus, with yellow flowers, as the main ssp should have.

We also found another thousand or more kots ssp elephants, I’ think my appetite has been satisfied for a while. MUST go back one year to see them all in flower! Late September, early October. 2015 is pencilled in. Coming? [Now in May 2014, as I tidy up the Diaries, we're getting ready to book our flights for Mexico 2014 pt 2 in October 2014 - just could not wait. The original trip planned for that time slot, a Matucanathon in Peru, has been pushed back until we have got this out of our systems.]
Tomorrow is just a 240 km drive to the airport & hotel (just a bit more than Pichidangui – Santiago.
Next morning I catch my flight early (take a taxi) while Cliff & Ian have to hang around until early evening – they arrive Thursday around 16:00 hrs, when we should be doing battle with Brussels’ traffic.

Early this morning, the clocks in the UK changed to Summer Time, so in theory, it’s ‘safe’ for me to go back home. I fly out of Mexico City on Wednesday, so excellent timing before it gets too hot here. The following weekend, the clocks switch to Summer Time in Mexico.

Manuel, our host in Hotel Boca Sierra (highly recommended if you are passing through, especially when all the building work in progress has been completed. Toilet seats would be nice!) is also keen on cacti – there is a small Rebutia muscula in a pot at the bar – the discussion focused on whether it is alive or not. Manuel insisted on showing us a habitat (S3130) for Lophophora diffusa, taking us along a poor track that was OK for his Nissan pick up, but tough going for the tyres of the Jeep Patriot.  We get the impression that these plants are quite common and given the right substrate and aspect, any stop will do to see these plants. Thanks for showing us these plants, Manuel! There was an interesting Agave too, sure to be in John Pilbeam’s latest book, with a name.

Next we returned to yesterday’s stop where Ian had found large numbers of L. diffusa and also some Strombocactus disciformis, but with the road cutting wall being in the shade at that time and in failing light, we had come back today to photograph the dozen plants in sunlight and look for some more. We did – at least a thousand of them! Ian (who else) managed to find the only plant in flower; well done again!

Strombocactus disciformis

‘What?!’ , I hear you say: ‘Another white flowered plant?’ Yes, but as these plants often grow in the shade, they still seem to be able to interest pollinators (although none seen).

On the flat, we found many clumps of Thelocactus leucacanthus – many of them looking quite beaten up, but others in bud or in flower. In this area north of Vizarron it is ssp. schmollii that occurs abundantly over the hillside. It differs from ssp. leucacanthus by having magenta flowers and the plants kindly obliged by showing them, proving that not all cactus flowers here are white.

But for me, the Strombos remained the stars of the day. I also have to compliment the Mexicans on MEX120, a wonderful asphalt road, with bits recently updated, taking out a few bends where the old road can still be entered for an easy car-park and hassle free photography.

The other bonus, staying in Hotel Boca Sierra, is that they make and sell all sorts of the local marble and alabaster ornaments. Ian has been ogling the alabaster eggs for his Mum, who has a huge collection of these. I could also not resist a few items (I wonder how much my luggage will weigh in at….. )

Tomorrow we might take another look at Zimapan to see if Thelocactus hastifer – in bud soon after we arrived, has sprung into flower yet.

We started off with a search of Turbinicarpus rioverdensis and Thelocactus hexaedroforus. We met a very nice Mexican, Ramon, who had spent some time in Washington State and who spoke very good English. We asked permission to walk past his house and through the allotments of the small community to reach the GPS coordinates. Sure, do you want me to show you? I know where the cacti grow, he offered. So do we, thank you very much. And so we walked the supposed 300 m past his house, through the allotments and found: no cacti at all. Hmmmm. Should we go back and ask for Ramon’s help? Then Ian (again) came up trumps, thanks to a single plant in flower. Cliff and I had soon joined him. And as always, find one plant and soon you find a dozen, all in a small area.

When we got back to the car we thanked Ramon and showed him the pictures. Wow! he said. These small plants grow here?! I never knew. So we saved ourselves quite a bit of time by turning down his services as a guide. Anyway, half the fun is finding plants that play hide & seek with you, even if it seems unlikely that you will find anything in a particular spot. Another new taxon for me on my tick list!
We’re in Vizarron, in the State of Quaretaro, within a day’s drive of our first night in mainland Mexico, in fact we passed by here from that first night’s hotel. Were booked in for two nights with tomorrow planned as Strombocactus Day. We cheated and actually, unexpectedly, found some on the last stop (S3129) of the day, near the town. Although the light was poor, I still managed some OK images, but we’ll go back to do it properly. Another ‘first time tick!

And in between, another tick, this time for Lophophora diffusa, so another great day, but getting into that ‘going home soon’ frame of mind. I bought a pair of moccasins made out of goat skin, hand crafted by a local craftsman in the high street. Should last me a lifetime, once my toe has healed.

I spent a good part of the day winding Ian up about the fact that in a week’s time he’ll have spent his first day back at work. But the real point is that there are still six glorious days to see cacti in habitat and a lot more images waiting to be snapped to remind us of the marvels that we’ve seen.

We started the day just 5 km or so from the Premier Hotel, Rio Verde, where on 3 March 2011 Eunice and I had searched and found Turbinicarpus lophophorioides and Coryphantha maiz-tablensis. Then the plants were very shrivelled up and difficult to tell apart. Nothing had changed much, including our inability to distinguish the two taxa – may be we were only seeing the one and did not tell which one it was! We resolved that if it was pulled into the ground, it was T. lophophoroides, else it was C. maiz-tablensis. Areoles & spine clusters were almost identical, all quite different from plants in my collection. But just as back home, it seemed that these plants were short-lived.

Next we went off to another 2011 stop. This time I was confident that we’d park the car and just walk straight up to the first electricity pylon where we’d turn left to find Ariocarpus retusus ssp scapharostrioides plus lots of other cacti. All the land marks ticked all the boxes – but there was just one aspect missing – the cacti! May be it was at the second pylon, or may be the third? By the time Ian had made it to the fourth pylon there was an enthusiastic wave from him – he had found them. By then, Cliff had given up in the heat and had returned to the car but this time with me as the key holder. As usual Cliff likes to do his own exploring and although I had shouted as loud as I could each time that we were moving on to the next pylon, he claimed not to have heard. He was not best pleased when we returned, but as all who have travelled with him will confirm, he is usually the last to return to the car, so I have had to wait many times.

Our next stop (S3124) was for Lophophora viridescens, just a quick 30 minute stop, near San Francisco. It took me just five minutes to gain the opinion that the conditions were wrong to find Lophos here, too dry in the open places, lots of cacti among the shrubbery and ceroids, but too much annual vegetation to spot tiny plants beneath them. The others confirmed my opinion 30 minutes later. Plants found include Coryphantha maiz-tablensis, Cylindropuntia leptocaulis, Echinocereus enneacanthus, Mammillaria sp. Myrtillocactus geometrizans, Stenocereus (Rittercereus) pruinosus and Tillandsia recurvata.

The next stop (S3125) was for the giant 3 meter tall Platy – Echinocactus platyacanthus that Eunice and I had first seen in 2011. Then, she had been on one side of the hill while me and the giant were on the other. I made three attempts to balance my camera on another platy and use the timer to take a picture of me and the giant – I failed. This time Ian obliged. As I walked up to the giant I was reminded of the opening number on Eric Clapton’s 50th Anniversary Concert at the Royal Albert Hall, where Angie had taken me for my 60th birthday: ‘Hello, old friend!’  In my alternative nomenclature system for individual cacti seen in habitat, this becomes PK#4 – Lanky (syn. Tally and Giant).

As in 2011, I probably took more images of Astrophytum myriostigma in flower here than on the rest of the trip put together. There was also a small plant that I first thought was Coryphantha maiz-tablensis, but as they got larger towards the top of the hill it was clearly a Thelocactus, presenting us with the problem of which one – T. hexaedrophorus was a candidate (but not recorded from this area), which would add another tick in the Thelo-list – but is it? And if so, which form? I’ll have to check what I called it in 2011, if indeed I recorded seeing it (I did not – or may be as a Coryphantha sp?). I’ve settled on T. tulensis based on information from literature.

We had passed all these stops yesterday and had bounced all this way again just to see these great plants. Then the plan had been to take the highway to Rio Verde and while I was having a snooze the plan got changed so that we ended up bouncing along a variable quality track. Then, we stopped in a hamlet where Ian bought two family size bottles of Cola and the elderly lady pointed out that there was a deposit on these plastic bottles. At the time we thought: ‘ yeah, what ever!’ Today he was able to return the empties.

Tomorrow we head south again.

Today was going to be a driving day, so I nestled into my ‘home’ for the last few weeks (back seat as Cliff had assumed the driver’s role, Ian the navigator role with me as director to specific locations guide) and closed my eyes – the quickest way that I know to make time pass by quickly.

When I woke up, we were bouncing along a rather rough track. What had happened? Change of mind, as we were making such fast progress, but on a road with little opportunity to stop, that Ian had found an alternative route that had turned out to be a little longer and significantly slower than had been planned, but still got us to Rio Verde in daylight, where we found a triple room at the Premier Hotel.

We made a number of stops along the track, but the images have already been backed up on my plug in HD, so the full details will have to wait until I review these Diary notes and fill in the blanks or make some corrections in weeks to come.

So here they are:

S3117: west of Ruta Federal 101, near Jaimes: Coryphantha sp, Cylindropuntia leptocaulis, C. sp., Echinocereus pentalophus, Ferocactus histrix, Mammillaria compressa, Myrtillocactus geomatrizans, Opuntia microdasys, O. sp., Tillandsia recurvata

Echinocactus platyacanthus - S3120

‘Fatty’ -Echinocactus platyacanthus – S3120

I have to admit to becoming really fed up with the names of my favourite plants changing continuously. I try to keep up, for the sake of good communication in the Diaries, in presentations and in articles, but names change faster than I can keep up with if Cactaceae Systematics Initiatives are to be believed.  Trouble is that at presentations I learn that most people still hang on to Backeberg names – no problem but it would be such a help if we could all stick to one, stable set of names. You may have noticed that in attempt to do this, Angie and I have started our own naming system, starting with ‘Smiler’ for a crested Copiapoa cinerea ssp columna-alba that we go and see each time that we pass through the Pan de Azucar National Park in Chile. After parking the car, Angie is able to walk straight through a field of 1,000 + columna-alba, straight up to the plant, so it certainly meets the criterion of being ‘distinct’, and yet there is no intention to suggest that botanically / taxonomically it is a different taxon.

Here is my second plant in this naming system (PK#2): meet ‘Fatty’ (a.k.a. ‘Michelinmanii’). Cliff’s pressence in the picture is purely to illustrate that there is no truth in the opinion that cactus explorers are the biggest threat to plants in habitat. We could not move most, even if we wanted to! In the ‘old system’ it is still known as Echinocactus platyacanthus. Tomorrow we’ll meet PK#3.

S3121: Disocactus sp, Fouquieria splendens

Disocactus sp - S3121

Disocactus sp – S3121

The plant above looks remarkably like ‘Aporocatus flagelliformis’ that we used to grow at the Holly Gate cactus nursery in the 1990s, except those plants tended to have their flowers nearer the base of the stem, rather than at the end like this one. Holding the branch to prevent the stem swinging in the breeze produced evidence that the plant had the same glass-wool like spines that I’d have in my fingers after repotting a few hundred plants for Terry Hewitt.

The track seemed familiar – was it the same track that Eunice Thompson and I had followed in the opposite direction in 2011? Yes, it was, but how did we miss the plants that we saw this time? That time we picked up a puncture and ended up buying a new tyre in Ciudad Victoria. This time we had no such dramas and promised to go back the next day to revisit some of the stops made in 2011.
