Title: Sedum from Macedonia
Post by: Great Moravian on January 26, 2017, 01:04:42 PM

I am not able to identify this Sedum from the Republic of Macedonia
photographed by Marek Chaloupka in 2014.
[attachimg=1]
Leaves are coloured and papillate as in Sedum laconicum but
totally differently shaped.
[attachimg=2]   juvenile plant
[attachimg=3]   adult plants
Variability or mix of two species.
Your suggestions please.

The narrower leaves probably belong to juvenile Sedum hispanicum.

I asked Ray Stephenson (Sedum Society) and he thought it might be a form of S. grisebachii.

I note Urs Eggli in the Illustrated Handbook of Succulent Plants: Crassulaceae mentions that grisebachii is highly variable and has been recorded in Montenegro  indeed there is a distinct form  S. grisebachii var. horakii .  I hope that helps.

Thanks. According to the publication mentioned by you, Sedum grisebachii should possess leaves green
and not glaucous, these papillate solely at tips and not troughout.
So I conclude, from the information given by you, that the inflorescences and the leaves in the centre
of the third image may belong to Sedum grisebachii var. horakii whereas
the glaucous leaves papillate troughout belong to Sedum hispanicum.
