One Mammillaria and one Coryphantha

Please help me to find the ID of these mammillaria:





i buy it as Mammillaria san-angelensis

and this Coryphantha?





Thanks!

Mammillaria san-angelensis is an old name. It has been "lumped" by Hunt into Mammillaria haageana, and considered by Reppenhagen to be synonomous with Mammillaria elegans, which itself is just a form of Mammillaria haageana. So I think the old name may have been right, but it is really Mammillaria haageana.

The Coryphantha is, I think, a young Coryphantha compacta. It is really quite difficult to identify plants before they have gained their adult spination. As you probably know, this only appears on Coryphantha plants after 5 or 6 years, maybe longer, when usually stronger spines develop, central or radial. This can change the appearnce of a young plant quite a lot. So, lots of caveats on my attept for a name here.

Thank You so much Crhis, as soon as the coryphantha gets bigger, i'll upload another picture

I bought the Mammillaria after seeing a video of her rescue from extinction by Mexican scientists of the Mexico's largest College (UNAM)

Mammillaria San-Angelensis

M. haageana is actually very widespread. The san-angelensis form is from the central volcanic region (Pedregal), and it could well be that the video you saw related to one population being over-run by the ever increasing need for houses, roads etc around Mexico City.

That's exactly what happened, I would like the video had subtitles so you could understand it better. I leave a picture of baby Coryphantha Octacantha. enjoy!

Greetings from Mexico City

Muy hermosas.

I saw C. octacantha just to the north of Pachuca in 2005. I hope to visit there again in April 2012.

Can you post a link to the video - my Spanish is poor, but I can try to understand enough.

It's linked in my previous message:

Youtube - Mammillaria San-Angelensis

The video talks about Tissue Culture!

Thought from picture it looked like M.Ruestii. Also part of the Haageana/Supertexta group.

I think this coryphantha is a retusa (http://www.cactuspedia.info/schede/CORYPHANTHA/Coryphantha_retusa/Coryphantha_retusa/Coryphantha_retusa.htm). Do you have a picture with flower?

Thank You Delandmo but I think Chris is right

42 As soon as it gets a little bigger or show a flower i'll post it, I think mine has a little more straight spines


Here's a picture of a Longiflora. Enjoy it

Nice M. longiflora. I was fortunate to see these in flower in Durango in April 2010, at Coneto Pass, also just off the Mex-40 some distance before El Ciudad, and again a long distance away near the Mex-16 in northern Chihuahua. They look wonderful, and your photo shows this species off to great advantage.

M.ruestii, which is one of the Supertextae series, is considered to be a synonym of M. columbiana ssp yucatanensis, and actually comes from Tegucigalpa, Honduras

Thank You Chris
