A beautiful species characterized by the shining hairs on the stipe and the 
shining white or metallic scales on the under surface of the segments. 
This is the species that I had previously identified 23 as A. lepifera J. Sm., but 
I am now convinced that it is a distinct species. The short description of 
A. lepifera J. Sm., given by Hooker 24 is quite insufficient from which to identify 
Smith’s species, except that it appears to be near, if not identical with A. to- 
mentosa (Blume), as Christensen supposes in his Index Filieum 44, or perhaps 
the same as Cyathea Loheri Christ. A. calocoma is distinguished from A. 
latebrosa, 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 
the base, as well as by the marked glaucescence of the frond. In A. latebrosa 
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, such as are 
found in A. calocoma. It is a delicate species with trifurcate nerves and a very 
rugose rachis. 
Var. congesta (Alsophila lepifera var. congesta 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,
