Ornithogalum sigmoideum vs. O. sintenisii
penstemon (Thu, 13 Apr 2017 09:24:59 PDT)

how does one tell the difference between these two short stemmed Mediterranean thogs?
Ornithogalum sigmoideum
Ornithogalum sintenisii
and is “Ornithogalum nanum” one of these?

Plantarium considers O. nanum to be a synonym of O. sigmoideum.
The differences between O. sigmoideum http://www.plantarium.ru/page/image/id/41420.html
and O. sintenisii http://www.plantarium.ru/page/image/id/70751.html aren’t easy to spot; might need a key.
Freyn was the author of both species so there must be differences.
