 Luzon. 



62. GEODORUM Jackson. 



Eleven species are apparently distinct. Geodorum is closely allied 

 with Eulophia. Geodorum nutans, the only representative of the 

 genus in the Philippines, is well characterized by the nodding 

 inflorescence of pale pinkish flowers.

63. DENDROBIUM Sw. 



Dr. F. Kranzlin in his recent monograph of the Dendrobiinae 

 (1910) admitted over six hundred species in the seven genera, 

 Dendrobium, Callista, Inobulbon, Sarcopodium, Diplocaulo- 

 bium, Desmotrichum, and Adrorhizon. In Dendrobium, as lim- 

 ited in the monograph, 571 species are given place. If we should 

 adopt the generic groups recognized by Kranzlin, the Philippine 

 species would be distributed among the following: Dendrobium, 

 Sarcopodium {Dendrobium acuminatum Rolfe, D. Lyonii Ames, 

 D. stella silvce Ames), Diplocaulobium (Dendrobium Clemen- 

 sice Ames), and Desmotrichum (Dendrobium chrysographatum 

 Ames, D. Eurorum Ames, D. interjectum Ames, D. pseudocon- 

 vexum Ames, D. puipureo-stelidium Ames, and several other 

 species). 



Dr. R. Schlechter, in Die Orchidaceen von Deutsch-Neu- 

 Guinea, criticizes the Kranzlin monograph severely, and with the 

 exception of Cadetia keeps Dendrobium intact and expresses 

 the opinion that Adrorhizon Hook. f. does not belong to the
