cheetialia erectiora, inferne latiora, marginibus recurvis reflexisve. Theca 
in pedunculo elongato, cylindracea, erecta, operculo dimidio breviore, pe-

Caulis 2-6 lineas altus. Folia 1-1} lineam longa, gramineo-viridia, 
inferne pallide fulvo-fusca, sicca crispata. Pedunculus 6—9-linearis. Theca 
lineam longa. 
The habit of this species is somewhat peculiar, and it may
