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.
