the valves oblong, ventricose, I to ij in. long, entirely 

 scariose at flowering time ; pedicel very short. The 

 flowers are dark violet and fragrant ; the perianth-tube 

 under an inch long ; falls obovate-cuneate, 3 in. long, 

 1 1 in. broad ; beard white, tipped with yellow ; 

 standards as long as the falls, orbicular, 2 in. broad ; 

 style arms above an inch long, the crests deltoid. This, 

 Mr Baker thinks, is a hybrid between /. Chamaelris and 

 /. pallida. It flowers late in May, and is known only in 

 cultivation. Cultivation is the same as for the majority 

 of the Pogoniris section.

 Mag., t. 5806, non-Lam. The rhizome is stout, short 

 creeping. The leaves are ensiform, glaucous, and at 

 flowering time 6 to 9 in. long, \ to f in. broad. The 

 stem is one-headed, \ to I ft. long ; the spathes two- 

 flowered, 2 to 2 \ in. long ; valves oblong, green or sub- 

 scariose at flowering time, ventricose ; pedicel very short. 

 The perianth-tube is an inch long, the limb of bright 

 violet purple, 2 to 2| in. long; falls obovate-cuneate, 

 an inch broad, the beard bright yellow ; standards or- 

 bicular, 1^ to \\ in. broad; style branches over an inch 

 long, crests deltoid. A native of Portugal and Morocco, 

 flowering in April. The flowers are fragrant. Is of 

 easy culture. 



The plant called I. biflora gracilis is probably a 

 cross between virescens and nudlcaulis.
