This is clonal material from a plant originally from N.W. of Damascus on the eastern slopes of the Anti-Lebanon range, close to the type locality of damascena. Though it does not fit the description in Mathew’s Iris book, it does fit the later A guide to species Irises.
The flower is huge, some 15 cm in diameter. The standards are whitish with thin, dense grey-lilac dotting, the falls are of deeper, violet-brown with more intense spotting and a blackish signal patch in the centre. Our clone, grown in pots reaches about 35 cm tall.
