 ing Iris, native of Oregon. It has solitary 

 rigid leaves 1-2 ft. long, and about ^ in. 

 broad, one side being green, the other 

 glaucous. The angled flower stem is

 of the Caucasus to Persia, about 6 in. 

 high, with 4-6 lance-shaped sickle-like 

 leaves. Flowers in February and March, 

 2-3 in. across, pale yellow ; falls obovate,

 greenish-yellow, except the central orange 



ridge of the falls. The standards are 

 larger than in the type, bent vertically 

 downwards, with edges sharply curled to 

 form a channel. /. assyriaca, with white 

 flowers, closely resembles I. caucasica. 



Culture dc. as above for ' Bulbous 

 Irises,' p. 917. I. caucasica and its vari- 

 eties are of more interest perhaps from 

 a botanical than a garden point of view.
