And so the car continued north, making a first stop of the day (S3828) at Quebrada El Leon, to see Copiapoa leonensis and Eriosyce (Thelocephala) odieri subsp. krausi (Ritter) Ferryman.

Plants extremely dehydrated, looking black (Copiapoa). As usual, the Thelocephala are hidden below ground and apparently less affected by the lack of water, so far. The Copiapoa leonensis still look like C. mollicula. When I have shown images to audiences in presentation in the UK, they thought that the plants were C. mollicula.

Despite the shriveled and blackened appearance of the plants, I take the Eulychnia that we saw to be E. breviflora, until at the beginning of the trail into the hills there were signs along the lines of the BCSS signs at Pichidangui, that suggests that this is Eulychnia breviflora subsp. tenuissima, I believe credited to Helmut Walter.

Next we stopped at the Orbicular granite exhibit (S3829), a rare geological feature, a plutonic rock type which is usually granitic in composition.

S3830 was past km 910, our usually stop to see Copiapoa calderana, but this time shot by, due to lorries hot on our tail! Good move Ian!

We took the next turning east, signposted to El Moreno, not a name that I’m familiar with, but probably a mine, 56 km inland. We made some stops around km 10 and found more Copiapoa leonensis and some C. calderana I assume, again, ID made difficult due to dryness.

And finally, on to the last stop before the hotel (S3831), at the stop that we christened ‘Hoot the Virgin’, as there is a monument here that now has small statues of presumed virgins on display. As Chilean drivers come by, they hoot their car horns, requesting a blessing. Ian and Al soon understood as the cars passed by!

And guess what, again the scene was extremely dry. We did find small plants of Copiapoa calderana var. spinosior – it seemed there has been more regeneration here during the last five years than elsewhere with quite a few small single headed plants the side of a large orange.

Were staying two nights in Hotel Aqua Luna, where we stayed before 2015, opposite a Chinese restaurant at the time. In 2015 the hotel had been badly affected by the floods. There was mud right up to the ceilings on the ground floor! Now everything is cleaned up and refurbished. There is a new Chinese restaurant three blocks into town, on the left hand side of the road. These last few details for Ian who is playing catch up with us.

Tomorrow we’ll see how the Pan de Azucar is standing up to these drought conditions and if Smiler has survived.

PS The server here is not uploading my jpeg files tonight – will try later.

I quite like days where we did not see much – there is just less to write up in the Diaries.

Ian and Al were keen to see the area where on previous (much wetter) occasions I had seen Euphorbia copiapina in flower. Sure, so we took the turning from R5 to Barranquillas where in 2004 the world had suddenly turned purple, with billions of Portulaca grandiflora in flower; with beetles stuffing themselves with pollen and with the sky filled with birdsong from birds feeding on the beetles. As I was taking pictures of this scene, my hands soon started to itch due to my allergy to Euphorbia latex.

In 2019 things were very much drier, resulting in no images of plants:

S3826: along the road from R5 to Barranquilla
No flora or fauna to observe. In 2004 this was a purple mass as far as the eye could see!

The second stop of the day was on Morro Copiapo where eventually we found our usual stop. It seems that a large are of rocks and hillside had been removed to be used for building materials to create new beach villages.

There were very few cacti to see. Many dead Eulychnia breviflora, a few still standing up and one with a flower and four buds! We eventually found a few clumps of Copiapoa marginata. This is the neo type of the Genus Copiapoa. Is this global warming at work?

Finally the top challenge of the day: find Eriosyce (Thelocephala) odieri – again, this is its type locality: One plant found!

S3826 Eriosyce (Thelocephala) odieri

Tomorrow we move on to Chañaral. Ian Woolnough’s group, the Magnificent Seven, report landing safely in Chile and should catch up with us in Taltal in a few days time.

Technically we made four stops today with the last stop at the cake shop on the corner of the old R5 and the road to Vallenar, but as I took no photos here, I have not allocated a Stop number.

For the first stop of the day, (S3822) we headed north along R5 and turned east at the difficult to see sign to El Donkey. This is now a good salt track. We briefly hit the beginnings of a pea-souper fog as experienced in 2003, but it lifted quickly, producing a bright sunny day, again at the expense of the fauna and flora. The Eulychnia were simply too dry to give an accurate ID but so far from the Ocean it has to be E. acida. These plants practise stem-sacrifice at times of extreme drought. They also demonstrated spine sacrifice with bald stems surrounded by piles of long spines. Not sure that this is a good idea on their part as the spines are useful to catch fog droplets and direct them to the plants root. I was bluffing about my ability to find the location for Copiapoa coquimbana subsp. andina having only been there on three previous occasions, the last one five years ago! Of course, I had brought my Garmin Nuvii SatNav along, but the wrong one – this one had my US and Mexico data on while the one with my Chile data is still in England!

Never mind, the location where I had been shown them by Rudolf Schulz appeared in due course along the side of the road and sure enough,we were able to detect clumps of Copiapoa on the lower part of the hill. We walked over for closer inspection and I managed some nice pictures.

Copiapoa coquimbana subsp andina

On another occasion, with Bart & Marijke Hensel, we were taken to another location and another and another, but the track that we had been on could not be found this time.

We wasted a bit of time trying to find the turning but then decided to head back via the Parque Nacional de Challe to see if we could improve on yesterday’s hunt for Eriosyce (Thelocephala) challensis. Checking back in the hotel last night it transpired that we had been on the wrong hill, 790 meters from the coordinates where we had found them in the past. It took about an hour to get to the ‘next’ hill but once again, it was very dry, so the chance of finding them was slim.

I saw Al lying flat on the ground and took a picture while composing the heading ‘BCSS Editor lies down on the job’ when he suddenly jumped up, did a little dance and called over: ‘Got them!’ And sure enough, he had found them, hence the stop at the cake shop where we had promised to pay for the cake of the first person to find the plant!

As usual, finding one leads to finding more.

As our special bonus we drove on in the direction of Carrizal Bajo where I knew of a population of Copiapoa dealbata – again, fewer in number and soon to become smaller still, as there were signs of a tunnel being built, presumably to stop the road from flooding.

Left: Ian; right Copiapoa dealbata at km 60 on road from R5 to Carrizal Bajo.

We took a good number of images before I allerted the others about the possible closing time of the Vallenar Cake Shop. Great how quickly everyone was back in the car.

PS Decided to go back to the Pizza restaurant on the Plaza, which was full of a happy family orientated crowd with lots of flag and banner waving people, all smiling, chanting and lots of pogo jumping. Ian and I bought a flag each in order to blend in. Got back safely to Hotel Atacama on Sereno.

S3817 was at Quebrada Barracota, along the Huasco to Carrizal Bajo road. The Copiapoa could be seen from the car but we needed a stop for an ID – Copiapoa echinoides.

S3818 at Quebrada Mala was an old favourite, first our group photo in 2001 very close to the Pacific Ocean, but since then along new improved tracks farther inland. Ian just did not know which clump to photograph first!

As always, we asked ourselves and speculated how old these plants were!

Al taking a close up – Copiapoa dealbata

S3819 was time for a little culture: The Carrizal Bajo Library – it looks as though they replaced the old bus with a new(er) model!

We turned east and headed towards Vallenar. If we just made a short stop in the Llanos de Challe National Park, we should be in time for a treat at the Cake Shop at the Vallenar Crossroads, opposite the Copec station along R5.

In the Park, I was sure that we needed to climb the first low hill after entering the Park, driving past the ranger’s station at the northern entrance. Wrong! Back in the hotel it transpired that we should have climbed the second hill. Never mind, we would pass here again. Extremely dry!

Yes, I know, they are a little (a lot!) out of synch, but it will all fall into place in time.

The plan for today had been to climb in a panga and be taken to two of the islands (Isla Choros and Isla Damas) in the Penguin Biosphere Reserve, north of La Serena. Cabanas, shops and the boats taking paying guests were were all in resting mode after partying during the recent Halloween festivities and the excitement and tension of the recent civil unrest. Many Chileans seem to have stayed at home to protect their property (?). Ruta 5 was practically empty.

After a cold night we woke up to the sight of flags flapping in the wind – not what we wanted to see! When we arrived at the harbour it was confirmed: too windy to make the trip!

OK, so over to Plan B: show my compadres ‘my’ Eulychnia chorosensis. Even in the poor light and their dehydrated state, they still looked like interesting, attractive plants.

Some years ago, Angie & I risked driving from Punta Choros across a barely marked track on very soft sand, but in a Toyota Hilux built for such challenges, to Carrizalillo. Now this was very easy on a smooth newly tarmacked road that would put most UK roads to shame. We finally found a shop open where we could buy some chocolate to replace breakfast this time.

The top quality tarmac continued all the way to Domeyko. Our second stop today was 17 km before R5 at the site for Copiapoa domeykoensis, said to be a giant form of C. coquimbana, in the north of that plant’s distribution area.

We hit R5 at Domeyko and headed north for Vallenar, where we missed the turning to our favourite cake shop and ended up on the road to Huasco. Never mind – cake would have to wait until later!

At Maitencillo we turned left on the track to Ojo de Agua for the third stop today for Eriosyce thelocephala lembckei. It really was very dry and the Eulychnia, Copiapoa coquimbana and Miqueliopuntia looked like shadows of their former selves. No Thelocephala found, although I feel sure that they were there, buried in the sand, laughing at us. Perhaps a but farther along? We we passed a sign to El Mirrador, offering a magnificent view? but now over chicken farms! All the previous plants mentioned were found, but no T. lembckei. I could hear the cakes calling my name at the R5 cross roads, so we continued back. Ian requested a quick look at a very similar layby with all the usual suspects and after some searching he waved to the car and begged us over. He had found Thelocephala lembcki, as small and hidden as I have ever seen them. Well done, Ian! Once we had spotted one plant, some two dozen more were readily found, but it is that first plant that matters!

For the 6th stop of the day I wanted to take us to the traditional Eriosyce napina site in view of the monster power station that burns oil pellets and spreads cancer among the people of Huasco. This has always proved a popular spot but this time there were wooden poles wrapped in barbed wire that blocked the road and it seemed that office buildings at the power station were still smouldering having been burned down, presumably by rioters.

We decided not to hang around in case of trouble and returned to Vallenar where this time we successfully made Stop 7 of the day: the cake shop!

We’ll be here for two – three more days so you may get a few more Diary updates.

We managed to squeeze five people into the car as we had promised to give Carlos a lift to La Serena. The social unrest and public strikes had taken their toll on public services, with buses running while they could rather tan to a regular timetable. None of us were too certain where we were going, but just before I thought that we’d soon be out of town, Carlos asked to be dropped off and we continued our journey, at least until the Copec station for fuel and of course, a hot dog!

We didn’t see much of the Cuesta due to the Camanchaca that sounds a lot more interesting when you read about it than when you are driving around in it! We had made the exit to Los Choros before we knew it. (S3805) There seemed little point at looking for Eriosyce riperia in this drought, the plants would be well hidden, pulled down into the soil by their contractile taproot. Soon after the turn we stopped for a leg stretch. A lot had changed since our first stop here on 24 June 2003, when it gained my location reference L0202, although all the cacti reported then were still seen today: Copiapoa coquimbana, Cumulopuntia sphaerica, Eulychnia acida, with somewhat hairier buds than ‘normal’ E. acida, and Miqueliopuntia miquelii.

S3805Copiapoa coquimbana

By 2007, the then newly described Eriosyce (Thelocephala) napina subsp. riparia had been added to the list, but time constraints stopped us today to search for it.

Next stop S3806 will always be known to me as JA001, Juan Pablo Acosta’s first recorded cactus stop. The scenery, from the top of a low hill, down the dry Rio Choros is great and creates many angles where it forms the backdrop for the cacti that grow here. Again, it was striking how dry the plants were. The Eriosyce here is called E. (Horridocactus) simulans as it closely resembles the Copiapoa coquimbana (Ritter’s C. pseudocoquimbana) that is grows alongside with. Except that today there were no flowers or fruits to differentiate between the two taxa.

The Eulychnia has a low, upright growth, not procumbent like E. chorosensis, but the hypanthium is bristly, just like E. chorosensis. Another mystery Eulychnia! A transitional form or a different taxon? It’s all happening in this area!

S3807 was a stop for a herd of some dozen guanacoes and later joined by a family ? pack ? of foxes. We tend to carry some bread roll remnants, left over from breakfast and they were very happy with this sudden meal! Only when we drove on did we see the request not to feed the animals, in Spanish of course, as inappropriate food for animals under stress could kill them! We hope that they are all OK.

(S3807) Zorro chilla

We arrived at the port of Punta Choros that seemed deserted. Under the overcast skies the shacks looked impoverished. All the pangas seemed to be in. There was a bit of a breeze, too heavy to take passengers to Isla Choros and Isla Damas where Humboldt penguins build their nests under the stems of Eulychnia chorosensis. Perhaps tomorrow? Come at 8:00!

We found cabanas to sleep four and, after a walk through the village found a restaurant that was open (or did it open specially for us?)

Fingers crossed that tomorrow’s weather will allow us to make the boat trip!

The last time I stayed in Guanaqueros on 27 November 2013 and before, in 2 January 2009, we visited the seaside resort of Totoralillo, the one south of Coquimbo, rather than the one north of Pichidangui, is was surprised to see the unusual hypanthium on the local Eulychnia. Was this a ‘sport’? But I also found similar plants at Playa Blanca and Tarambola.

So what is so different? An important means of differentiating between different species of Eulychnia lies in their hypanthium. E. acida has a naked hypanthium, covered in scales with just small insignificant bristles emerging from between the scales . E. breviflora on the other hand is covered in long, honey coloured wool. As you can see in the images to the right, the hypanthium of the plants that grow here is a mixture of the two, with the lower part covered in long wool but the upper half of the hypanthium clearly displaying the acida-like scales.

During the 2009 visit, this phenomenon occurred on ripe fruits and the long hairs readily rubbed off. I had not seen E. breviflora fruits in such an advanced stage of ripeness. Is this what happens in all Eulychnia fruits?

But this time, the hypanthium was that of a bud, not a ripe fruit. Flowers appear at the shoulder of the stems (cf. lateral for E. acida and apical on E. breviflora).

Eulychnia hybrid acida x breviflora?
Eulychnia cv April Fool’s Joke.

‘Should we start thinking of a new taxon?’ Ian and Al asked. I smiled. ‘Not until I have looked up the Latin for ‘1st April”

We went back to the cabanas so that I could roughly plan what we were going to do during the next few days. Suddenly there was a rumbling noise and the cabana began to shake. The fridge started to walk across the room. Then everything was quiet again. We had just experienced a 6.8 strength earthquake! But that is quite a regular occurrence in Chile! We saw no obvious damage – everything that was going to break, fall over or get knocked down already has!

Tomorrow we drive to Los Choros.
