272 CLI. IRIDEX. (J. D. Hooker.) (Iris. 
The Himalayan species of Iris are very imperfectly known ; good specimens and 
drawings are much wanted, with descriptions from the living plants. 'The common 
I. Xiphion of Europe and the East advances into Affgbanistan, but has not Wee 
collected in British India, and Prof. Foster informs me that he suspects that e 
European and Eastern I. Sisgrinchium, L., a species with the filaments united Zi 
low, occurs in the Punjab. Itis a native of Affghanistan. The character of bear 
and crested sepals is artificial and inconstant in this genus. 
* Rootstock a coated bulb or corm (Xiphion).
