Eriosyce & Copiapoa ID

Post by toson »

there're all in 4 inch spots.

1. the seller told me it's eriosyce senilis coimasensis, i do have another coimasensis with yellow spine, if this one is coimasensis or not?

2. Maybe eriosyce vexata or sth. else looks over-nutrition.Huge body with short roots and weak sticks.

Eriosyce villosa & Eriosyce paucicostata ?
If your cacti mess in your job just forget about the job.

The flowers on the first one certainly look like my coimasensis.

thanks, pinkish red flower means they live in the south of Atacama desert near Talal just like eriosyce taltalensis.

1: Does indeed seem to be correct
2: I would agree with 7george that it is probably paucicostata
3: I'm not too familiar with Copiapoas, but that could easily be a cinerea, maybe the variety "minicarpa" - apparently they only develop the white wax when exposed to intense sunlight.

All Neoporteria sensu stricto flowers are virtually the same with the inner petals surrounding the filaments and anthers, only really differing in size in the different species.

Looks OK for coimasensis to me, as all the senilis group (senilis, nidus, multicolor, gerocephala) are variable in their spination.

I would also agree the other one is probably the green bodied form of paucicostata.

Glad to see U & Dave made the same conclusion on coimasensis, in fact i have different coimasensis from different sellers .How about this one full of golden spines ? it's my first 'coimasensis' which looks like eriosyce sociabilis maybe it is! :D

You may find these articles on the generic confusion surrounding Eriosyce and Rimacactus of interest. You need to scroll right down towards the end for them.

You give me too much credit, I just checked against the photos on Llifle.

As for the second possible coimasensis, if the colours of the spines in the photo are accurate to real life then it doesn't fit in with Ritter's or Katterman's description of coimasensis.

Taken from p1041 of Ritter's Kakteen in Sudamerika Book 3 - Chile (the Google translated)
Spines very variable, greyish brown, greyish-yellow or greyish-black, more rarely gray-pink, the Rst. always brighter than the Mst. until almost white, when they are very fine; St. often finely needle-shaped, especially the Rst., Often stronger; Mst. Always stronger than the Rst. and sometimes thick and pretty; Rst. 15-30, on old heads often half out of the way, radiating laterally in younger plants, around the ar., Straight or slightly bent towards the body, 1-4 cm long, depending on the specimen; at the top of the ar. sometimes a few more fine short sts can be added; Mst. Ca 8-20, some of them in semi-sandy position, but of strength and appearance of the remaining Mst., Diverging, straight or more often curved, usually 2-4 cm long, sometimes up to 7 cm.

Taken from p113 of Katterman's Eriosyce (Cactaceae): The genus revised and amplified
32.2. E. senilis subsp. coimasensis (Ritter) Kattermann
Spines straight to curved, thin, needlelike, greyish to blackish, radials 15-30, 10-40 mm, centrals 8-20, 20-40 mm.


I was going to post a little ramble about Eriosyce, but I'll save that for another post when I have more time and energy :lol:
