After much consideration I have determined upon regarding the plants re- 
ferred to this genus as distinct from both Spiranthes and Pelexia. From the 
former they differ in their large showy flowers, great coloured bracts, and 
the want of calli at the base of the lip; from the latter in the former cir- 
cumstance, and in their rostellum being peculiarly hard and horny, remain- 
ing as a rigid spine upon the apex of the stigma, after the pollen masses 
have fallen away. Moreover, the plants referred to Pelexia have a lip 
which is dilated, not contracted, at the end.

Although closely akin to S. orchioides, this seems really distinct in its 
short pyramidal inflorescence, and especially in the form of its lip, which 
has a patch of hairiness near its middle, both on the outside and inside.
