It is possible that this fern may be a very small form of A. glabra; 

 the upper part of the leaf resembles very much the outer part of a pinna 

 of that species, still I believe that it is specifically distinct. I am con- 

 vinced that it is not identical with the South Chinese A. podophylla Hook., 

 as Christ suggested. This is said to have black basal scales and a 

 muricate stem. The rows of sori in A. kohchangensis are not shaped 

 like an inverted V as in A. glabra, and its much reduced lower pinnæ 

 and pinnulae are a character not mentioned in the descriptions of A. glabra 

 and A. podophylla to which I have access. A. dubia Bedd. is an allied 

 species, but according to description and figure rather different. Cyathea 

 Bonii Christ, referred by Christ himself to A. podophylla, is according 

 to the description very near to our species, but Christ describes the pinnæ : e 

 basi dilatata late lanceolatis.

This species, common from Japan through tropical Asia and Poly- 

 nesia, has been collected fairly frequently in later years in South Brazil and 

 adjacent countries. Probably it has been introduced there and escaped 

 from gardens.
