Amphicosmia Walkera, Moore. Mr. Moore places this plant in the genus AmiMcosmia, distinguished from Cyathea by the involucres 
being half cup-shaped ; but Mr. Thwaites, who has noticed living specimens, informs me that the involucre is very variable, and ranges 
between Cyathea and true Alsoi)hila.

often again divided obtuse, involucres sub-cylindrical and quite sunk, the mouth more or less spreading, obscurely 2-lipped, receptacles 
exserted.

I have lately found this species abundant on the Western slopes of the Nilgiris, 3,000 feet elevation.

divisions, broad lanceolate, the segments all acute, linear simple or forked, involucres superaxillary on short segments, partially sunk, short,
