"Acanthocalycium kuehassii"

[eddytrain]

Hello,

This plant was sold as an Acanthocalycium kuehassii, but that doesn't exist...
An idea about the real name ?

Thanx,
Eddy

acanthocalycium glaucum?

[phil_SK]

It does exist but it was published as a Lobivia and it isn't spelled quite right, which is why your search may be struggling! Walter Rausch published it as Lobivia kuehhasii, in honour of Franz Kühhas, in 1990. It's arguably no more than a form of Acanthocalycium thionanthum (the normal ssp rather than ssp glaucum, despite its slightly glaucous epidermis).
Mine for comparison:

As Phil says it does exist. Piltz in his seed list again spelt it with a single "h" and says:-

"A. kuehasii Sa. Famatina, (southern form of A. glaucum)"

It is now getting difficult to distinguish between Acanthocalycium and Lobivia because the once clear-cut spiny tipped scales on the flower tube of Acanthocalycium seem to blend more and more into Lobivia as the tubes get hairier. I had a couple of plants from Roger Ferryman where it is hard to decide if they are Acanthocalycium or Lobivia and like kuehhasii they have been tentatively put in both genera in the past. The hymen where the stamens arise in the flower throat is also not diagnostic since some Lobivia's possess that too.

The original characteristic of almost naked tubed Acanthocalycium flower with the dead tipped spiny scales on the flower tube.

Lobivia/Acanthocalycium ex Ferryman. May in fact be kuehhasii from Famatima?
