This beautiful plant belongs to the group of species formed by I. 

 caucasica Hoffm. and its allies, and seems to be nearest related with 

 I. palaestina (Baker) Boiss. It is chiefly distinguished from that species 

 through its considerably larger purplish flowers, further by its obovate- 

 spathulate interior perianth-segments, etc. I. paiaestina has pale yellow 

 flowers, which are sometimes tinged with lilac; its interior perianth- 

 segments are narrow, linear-lanceolate; besides it has a considerably 

 more southern distribution, extending from Syria and Palestine to Meso- 

 potamia (according to Boissier, Fl. orient., V, 122; its occurrence in 

 Mesopotamia is not mentioned by Baker, Handb. Irid., 45). From the 

 Syrian desert Post has described a variety with blue flowers under the 

 name of var. coerulea (Fl. of Syr. and Palest., 768). I. caucasica, of which 

 I have seen in Boissiers herbarium Armenian specimens from various 

 collectors, having broader, inflate spathes and obtuse stigma-lobes, is still
