S. borisii - unvalid name

According to Urs Eggli Sukkulenten Lexin - Crassulaceae the name S. borisii is no longer correct.

S borisii Degen & Urumov, 1915 =

= S. ciliosum fa. borisii (Degen & Urumov) H. Jacobsen, 1958 =

= S. ciliosum var. borisii (Degen & Urumov) P. MItchell, 1979 =

= S. ciliosum subsp. ciliosum

This plant ia a species and not a cultivar so it's name should not be written as:

Borisii

or

S. ciliosum "Borisii"

which suggest the cultivar is in question.
