 Some new species and varieties of Biiiai* 



For a number of years the writer has contemplated publishing 

 a revision of the musaceous genus Bihai. Inasmuch as this has 

 been much delayed, it has been thought wise not to withhold the 

 publication of the several new species which have come to light 

 in the course of the work. In order to enable the student rightly 

 to place the new species among the old a key to all the species 

 is also given. The preparation of this in turn has involved the 

 revision of the subgenera and minor groups which is herewith 

 presented. 



Intrageneric Relationships. — In previous treatments the species 

 have been grouped under two subgenera, which under somewhat 

 varied characterizations included respectively the large species 

 and the small species. The first of these to receive a name, 

 Taeniostrobus , was founded by Kuntze on his B. imbricata. Baker, 

 however, ignored Kuntze's name and included this species under 

 his own subgenus Platychlamys, with B. Bihai as type, which was 

 taken as synonymous with Taeniostrobus by Schumann and 

 replaced by it. The narrow bracted species were thrown together 

 b\- Baker under the name Stenochlamys (type B. psittacorum) and 

 this was adopted by Schumann. While one recognizes a more or 

 less natural subdivision of the genus around these types there 

 are no characters by which it can be so divided without tearing
