This species also approaches very closely to C. Cumingii, but is distinguished by its 

 tessellated leaves and dwarf habit. I have never observed in any other species of 

 CJiiisqiicfi two perfect flowers in the spicule, although Xees observes that they are some- 

 times found in C. tenella.

This a))])roaches very closely to C. aiiiUna, which is very ])rol)al)ly only an alpine form 

 of this species. It is also nearly allied to C. Cumingii; and I am unable to assign any 

 good distinguishing character to C. brcriglumis of Philijipi. Tlie latter appears to be a
