A beantiful speeies characterized hy the shining liairs on the stipe and the 

 shining white or inctallic scales on tlie nnder snrface of the segnients. 



This is the species that I liad previonsly identified "^ as .4. lepifera J. Sm., but 

 1 am now convinced that it is a distinct species. The sliort description of 

 A. lepifera J. Sm., given by Uooker " is quite insufficient froni which to identify 

 Hmith's species, except tliat it appears to be near, if not identical with A. to- 

 mentosa (Blume), as Christensen supposes in liis Index Filicum 44, or perhaps 

 the same as Cyathea Loheri Christ. A. culocoma is distinguished from A. 

 kiteirosa, with which it shares tlie 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 tlie marked glaucescenee of the frond. In A. latehrosa 

 I have never observed the exce])tionally long scales wliich 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. congcsta 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,
