This new Iris is one of the many novelties which have 

 been discovered lately by the Russian collectors in the 

 mountains of Turkestan. It was sent home alive to St. 

 Petersburg by Dr. Albert Regel, after whom it was named 

 by his father. The only wild specimen we possess in the 

 Kew Herbarium was gathered by Felisson in 1877. In 

 habit it most resembles I. pallida of our old familiar 

 European types, and it has the same scariose spathe-valves. 

 It is interesting botanically, because it possesses a rudi- 

 mentary crest and a fully-developed beard down the claw 

 of the outer segments of the perianth, so that it forms a 

 connecting link between the sub-genera Pogoniris and 

 Evansia. Our drawing was made from specimens fur- 

 nished by Professor M. Foster, F.R.S. In England it 

 flowers towards the end of May. 



Desoe. Bootstoch stout, shortly creeping. Leaves ensi- 

 f orm, slightly glaucescent, one and a half or two feet long, 

 above an inch broad. Inflorescence a lax panicle over- 

 topping the leaves, with five or six heads ; spathe-valves 

 ovate, ventricose, the outer scariose at the flowering-time, 

 except in the centre towards the base ; pedicels very short. 

 Flotvers bright lilac ; perianth-tube under an inch long, 

 narrowly funnel-shaped, greenish ; outer segments obovate- 

 cuueate, reflexing, two inches long, under an inch broad, 



OCTOBEB 1st, 1888.
