POGONIRIS 135 



feature, and this may be recognised at once by its very 

 obtuse leaves. The rootstock is robust and shortly 

 creeping. The leaves are pale green, ligulate, obtuse, 

 the largest 6 to 8 in. long at flowering time, and I in. 

 broad. The stem is a foot long, bearing one terminal 

 head and one sessile cluster below ; the spathe-valves 

 are oblong, vefy ventricose, 2 to 3 in. long, pale green 

 at flowering time ; pedicels very short. The perianth- 

 tube is short, limb sulphur yellow ; falls obovate- 

 cuneate, 2 in. long, by an inch broad above the 

 middle ; beard orange yellow ; standards as long as the 

 falls, cordate orbicular, with short, narrow claw ; style 

 branches pale yellow, an inch long ; crests deltoid, 

 irregularly toothed on the outer edge. This very 

 distinct species was discovered by the late Lieutenant- 

 Colonel Henry Lake Wells in the Province of Mazan- 

 deran, on the south of the Caspian Sea, and by him was 

 sent to Kew. It grows there on a south border, 

 apparently doing well.
