two on each peduncle, continuing long in perfection, and of the 

 purest white. Sepals, as is usual in this genus, coalesce at the 

 base, and form a sort of cup ; the upper one lanceolate, and pro- 

 longed for an inch into a slender awn ; the lateral sepals wider, 

 and joined together much further than the upper one, and end- 

 ing in short, slightly decurved awns. Petals oblong, slightly 

 sharp-pointed, curved inwards about the length of the lip. Lip 

 very small, oblong, acute, emarginate about the middle on either 

 side, with three nerves down its centre, of which the two lateral 

 ones are somewhat elevated.
