Don't know if this the same as T. krainzianus f. minimus but it does look like the juvenile stage of that. you can see 5 years old pictured below

Are these seedlings? How old? Is it safe to assume that they are naturally cylindrical, not etiolated?

Might be something obvious like M. elongata.

it looks very simailar to a Escobaria leei that I have.

I would go with James on this one

Alex

These are cuts from a grafted one in Myrtillocactus, I don´t have pictures of the mother plant but they are clumping and cilyndrical and mine are not ethiolated. I have not seen the flowers. He has a tag of some kind of M. gracilis, but it could be something else. Escobaria sneedii ssp leei is a good option. Thanks for the advice.

Alfonso,

Do you think yours is similar to this one?
{{gwi:493102}}

Then you almost can read which species it is and I'll tell you later what you have to expect with it.

Jordi

Oops, silly me. I read too fast so didn't see the word "Mammillaria" in yoor original post but just saw the word "gracilis" so I was thinking Turbinicarpus!! lol

Now I'm not so sure what your's are.

Hey Alfonso, congrats!!, that is a beautiful little plant it's Pygmaeocereus densiaculeatus, (to the splitters) which is now called Haageocereus lanugispinus as in Jordi's pic. Other pygmaeocereus are still remain with the genus name pygmaeocereus.
I love these little cereoids, they are such tiny plants, I had a crested form of this at one stage, and would love to get my hands on onther.
Check out this link, I think it will help.
Pygmaeocereus

Cheers mate, CP

Hello All,

I recently sent this explanation to a Peruvian aficionado:

.... here are photos of my plant, which according to Fr. Ritter's description and pictures in his 4 volume book 'Kakteen in Südamerika' certainly is Haageocereus lanugispinus..
For a long time this taxon erroneously had been called Pygmaeocereus densiaculeatus due to Backeberg's generic misplacement in 1966.
Ritter found that taxon already in 1957 in a tiny area north of Pativilca in the flat coastal zone near or at the boarder line of Depto. Lima and Ancash.
In his book he finally described it by the name which had been used before as nom. nudum in the nursery of his sister H. Winter.

Hoping that at least somebody might be interested in the history of this species.

Jordi

BTW, CP, grafted crests of it are waiting for you in my GH.

Is it possible to get seeds of H. lanugispinus anywhere? or non-grafted plants?

Tom

Thank you for your ID, and your information. I am going to wait until grows bigger and began to clump.
Alfonso

Some months later and this is it
Clumping on it´s base

Saludos

Here is a link that might be useful: {{gwi:493097}}

Bear in mind that 'mammilaria gracilis' is a subspecies of mammilaria vetula

positively lascivious, Alfonso. lol - jo
