S. pumilum from Elbruz, Iran

S. pumilum from Elbruz Nr. 1

A very distinct form collected by Dr. Giuseppi at 3000 metres on Mount Elbruz. Rosettes are about the same as those of the Adyl Su forms. The rosettes are distinctly globular with very fleshy incurved leaves (even in summer), oblanceolate and glabrous except for a few scattered hairs on midrib, margins and apex. The rosettes are a deep green with the outer leaves becomming stained with light red especially so on the apex. Quite a notable feature of this form is the persistent stolons that often grow outward beneath the ground, forming new rosettes quite some way from the parent plant. The inflorescence tends to be smaller than the type with flower petals of a paler colour. Despite being collected at such a great altitude it is quite easy to grow and increases well.

S. pumilum from Elbruz Nr. 2

This form we received from Hugh F.R. Miller with the assurance that it was a plant collected by Dr. P.L. Giuseppi on Mount Elbruz. Dr. R.S. Wale made no reference to this form when describing the various forms of S. pumilum collected in 1935 on the Caucasian expedition. Dr. Gíuseppi - when making reference to S. pumilum states it varied considerably - which appears to be quite different from any forms described by Dr. Wale.

Rosettes sub-globular, dense-leaved and of a dull green colour, the leaves are pubescent with strong marginal cilia. A notable feature is that the leaves are not incurved, but erect or half open, tight set in the rosettes with the inside leaves only a little shorter than the outside ones. The offsets are numerous and carried on short and quite stout almost decumbent stolons. Inflorescence is much smaller than the type and very few-flowered, petals are a rich purple. Cultivation is easy.

Very interesting !

Have you the paper of this expedition ?

No, sorry, I don't.

Thanks Renee

I don't think Mt.Elbruz is in Iran. There is Albroz in Iran that is oftenly mixed with Elbruz

What do you think where was this expedition?
If it was on Caucas, than plants must originate from. Mt.Elbrus (Elbruz)
in Russia, not Iran.
