6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 65 



recurved apices of the dorsal scales and lacking altogether the fine 

 silky white covering described as characteristic of C. ornatissima. 

 Their structure is equally distinctive, the cells being mostly large, 

 widely pentagonal or hexagonal, with yellowish sclerotic partition 

 walls and large lumina, contrasting in a very pronounced way with 

 the finely lineolate scales of C. ornatissima. The rhizome scales are 

 very different also, as may be noted from the description, the divari- 

 cate-flexuose tips and strongly toothed margins of C. Incarum being 

 characteristic.
