A hoantifnl species ohnracterized by the shining hairs on the stipe and the 
shilling white or metallic scales on the under surface of the segments. 
Tliis is the species tliat I had previously identified" as A. lepifera J. Sm., but 
1 am now convinced that it is a distinct species. The short description of 
A- lepifera J. Sm., given by RooJcer^* is qiiite insufficient from -which to identify 
Smith's species, except that it appears to be near, if not identical with A. to- 
mentosa (Blume), as Ghristensen supposes in his Index Filieum 44, or perhaps 
the same as Cyathea Loheri C^hrist. A. calocoma is distinguished from A. 
l<itehrosa, with which it shares the character of the costal and costular scales, 
by its whitish scales and by its basal segments being free and attenuate toward 
Ihe base, as well as by the marked glaucescence of the frond. In A. latehrosa 
I have never observed the exceptionally long scales which are shining, silvery or 
somewhat golden in color and strongly pointed, 4 to 5 cm. in length, sucU as are 
found in A. calocoma. It is a delicate species with trifurcate nerves and a very 
rugose rachis. 
Var. congesta {Alsophila lepifera var. co^gesta Christ in Bull. Herb. Boiss. 
6 (1898) 137). 
This variety is identical with the type in having the same very large basal, 
scarious, silvery, subulate, 5 cm. long scales which are 4 mm. wide below,
