I've been pouring through these pics for a few days now, some awesome porn, some funny pics (like the san pedro eating turtle- in peru even turtles can be shamans :P ), great scenery, and a few puzzles. Like in the Trichocereus in South America\Peru\Lambayeque folder, those are shots from brujos market stalls in peru. Lots of herbs I couldnt identify but correct me if I'm wrong but some of these cacti looks to be a different species of Trich than is whats normally regarded as active and its being sold with active san pedros in multiple stalls. The 15-18 ribbed ones.

Yeah, there was a little debate about those particular plants in a different thread. I'm far from convinced they are Trichocereus at all. Besides the rib number there are a couple other things that make me hold that view, including how the ribs are much more angular than rounded like the obvious T. pachanoi, and how the areoles themselves sort of protrude off the plant towards the tip rather than being slightly sunken.

I suspect they are a species of Armatocereus, but clearly not A. laetus which Wade Davis says is used similarly to San Pedro in areas surrounding Huancabamba, and Carlos Ostolaza claims is "pishcol blanco" and used similarly to T. pachanoi. The only Armatocereus addressed by Anderson that comes anywhere close to that in the photo is A. arduus which is described, among other features, as being 10-13 cm (3.9-5.1 in) in diameter with 8-16 ribs which are 1-2 cm (0.4-0.8 in) high. It can have 1-3 spreading centrals that are 2-10 cm long, and with 6-12 diverging radial spines that are a few millimeters long. If the plants in the above photo are that species then the spines are obviously broken off as with the T. pachanoi spines. A. arduus is "poorly known" and is from the "valley of the Marañón." Now the Rio Marañón's closest point to the town of Huancabamba is about 100 km. But then again the Rio Marañón is about 200 km from Chiclayo.

Anyone have vol. 3 of Ritter's Kakteen in Südamerika (see pages 1271, 1273, A1137)? I think there is a picture of A. arduus in that volume. Otherwise I can't find a picture. I saw somewhere that A. rauhii v. balsasensis was synonymous with A. arduus, but I'm not so sure.

Wow! Those are some fat logs!

+1 that the 16-18 ribbed ones are probably/possibly Armatocereus - I have no suggestion as to which species (and thus I'll concur with M S Smith). The logs in the pic are either de-spined or someone has the ultimate patch (pach) of spineless clones! :drool2:

Armatocereus are beautiful and are on my list of plants to get. Check out these pics here and here - how could you not love'em?

I'm really partial to the matucanensis - such short chunky segments and that delightful silver frosting...... phwoaar!

I dont get it any better. The plant looks thinner than the fatties in the pic but the description fits pretty well. I am going to have a closer look at the description later! bye Eg

Evil, that's strange as the plant in the foreground doesn't look like a Armatocereus at all as it doesn't have the segment growth of an Armatocereus (those in the background do though). This plant in the foreground also looks to have a thicker coat of spines than I would have expected on A. arduus, as well as appearing to have cephalium, something Armatocereus don't have.

Are you positive you are ready the caption right?

Hi Michael, yeah i mean the one in the background. The one on the left is Espostoa Mirabilis. The pic is a little bit confusing but I just tried to get the whole scene on the pic to point out the dimensions. From what i can recognize on this crappy shot, it looks like the colums might be a little bit thinner than the ones in the SS Pic! But it could definately fit. The Description matches perfect. Atm it seems that there is no better pic of Armatocereus Arduus in Ritters Book than this one. But i´ll check my other books too. Maybe there is a nice pic in Backebergs books. bye Eg

EG, my Cactus Lexicon (1976) by Backeberg simply says "A. arduus Ritt. (FR 1060): no description available." I'm a little less concerned about the diameter of the columns in the Ritter picture than I am about the segmentation lengths. There are two different photos in the torrent of the plants in questions, but in neither case can any segmentation be clearly seen.

I had some time to check Ritters description more intensively. Everything fits if there wouldnt be the part with the segmentation. :-) I know the SS-pics from the Cactus-market and none of the plants showed the distinct segmentation that is typical for Armatocereus. I was assuming that it might be possible that A.Arduus does not show such a distinct segmentation but thats clearly not the case. Its rather the opposite. A.Arduus has one of the most distinct segmentations from all the Armatocereus. I have Backebergs six volumed Cactacaea, which might contain more pics than the less voluminous Cactus lexicon. But i doubt that Backeberg printed a pic of a plant that Ritter discovered. They were arguing about numerous Armatocereus species because Ritter declared some of Backebergs "discoveries" as nomen nudum. bye Eg

Anderson, presumably quoting Ritter, says "stem segments erect, gray-green, becoming bluish, 10-35 cm (3.9-14 in) long." The SS picture above and another in the Torrent file don't seem to show the full length of the cuttings so I'm not sure they can be disqualifies as being A. arduus unless we can see the full length. If you look at the picture above you can see at the center bottom of the picture the lower end of one of the column and it does appear to tapper inward quite sharply, but since we can't see the right side of the column we can't tell if the column is actually just bent. If these are segments they are certainly on the long end of the spectrum.

Interesting that no photos of A. laetus, a claimed San Pedro aligned plant, have shown up in some of the market photos. Make me wonder if the plant Wade Davis saw in the market was in fact the plant in these photos (which clearly isn't A. laetus). Certainly the plant in these photos is much more similar in appearance to T. pachanoi than A. laetus.

I hope we can figure this little conundrum out.

I got the pic-pack. It fixed my mood a bit , I am not in one of my best days today...

Seeing plants in habitat is really a delight!!!

Hi everyone

I am currently in Bolivia and heading to Peru sometime in the next month or so

I don't want to sit in internet cafes reading about cacti all day while I'm travelling, but if anyone wants to send me simple instructions on where to go and what to look for, I will attempt to do so and take good photos.

I don't have a strict itenerary, so if something interesting comes up and it is not too far from a place I was intending to go anyway, I can go.

cheers

Download the torrent as it has some fairly good pointers about locations. I would of course suggest you visit the plants of Huarochiri/Matucana, particularly at Catarata de Pala Kala, Antankallo, and the Catarata Huanano. This are but a short trip from Lima. If near Cuzco be sure to visit the Casa de la Gringa. In Bolivia I'd love some exploration for the elusive T. riomizquensis which should be in the region of the Rio Mizque near Cochabamba.

Good luck and the more pictures the merrier.

mutant, glad you got it all. Fantastic eh?

mutant, any info in your Ritter about a more specific region than simply the valley of the Marañón for A. arduus? If I could have something more I'd be in a much better position to find photos.

Hi Guys! As soon as i have a holiday, I will have a closer look. Sometime during the week. Im sure that Ritter wrote something about it. The question is if i´m able to find it fast. I have 6 or 7 books from Ritter but due to my work i rarely have the time to read them. bye Eg

Its seed-buying time and I'm still thinking about that mystery cactus with the pedros in the brujo market :lol:

Ok, that market was in northern peru.. Browningia microsperma is from northern peru, its an Armatocereus relative with 12-20 ribs, 30+ small spines per areole (prolly easy to rub off leaving the areoles naked as in pic) but I cant find many decent pictures.. but if you squint at this one it looks pretty similar, doesnt it

b_microsperma_c_600.jpg

This species used to be called Trichocereus microspermus.

Anyone have a better pic of an adult specimen?
