Dendrochilum Loheri, as indicated above, is a near ally of D. 

 venustulum (Ames) Pfitz. It is also closely allied with D. stricti- 

 forme (Ames) Pfitz., from which it is readily distinguishable by 

 means of its very dissimilar labellum. The flowers are much larger 

 than those of Z>. venustulum and are borne in loose racemes, and 

 the narrow leaves and different habit are quite distinctive, while 

 the reniform apical lobe of the labellum overlaps the lateral lobes, 

 — a characteristic which I have not noted in D. venustulum. The 

 specimens on which my description is based were collected by 

 A. Loher. I found them mounted on the same sheet with D. cin- 

 nabarinum in the United States National Herbarium. I have 

 marked the specimen on which D. Loheri is based no. 461 A 

 {D. cinnabarinum was distributed by Loher under the num- 

 ber 461). 



Though additional material from the Philippines may break 

 down the distinctions between D. venustulum and D. Loheri, 

 which I now regard as specific, the specimens thus far studied do 

 not make such a result seem probable.
