ORCHIDACE.E 



ish, tinged with lavender-purple. The carinae of the labellum ex- 

 tend onto the middle lobe, the lateral ones terminating in mi- 

 nute rounded wart-like protuberances. Toward the base and mid- 

 dle of the labellum the lateral carinae are much higher than 

 elsewhere. The middle carina is represented by a thickening of 

 the mid-nerve until it reaches the mid-lobe on which it termi- 

 nates in an erect plate nearly 4 mm. high. In this respect the 

 general appearance of the middle carina recalls Z>. conanthum.

Dendrobium (§ Rhopalanthe) polytrichum Ames in Phil.

The use of the stems of this species in decorative work in weav- 

 ing recalls the similar use of Dendi^obiuvi utile J. J. Sm. in the 

 Moluccas where the stems enter into the fabrication of small 

 articles such as cigar pouches.

 (1912) 1577. 



The original specimens of this species were secured by A. D. 

 E. Elmer on Mount Giting-giting on the island of Sibuyan. 

 Why the specific name mindanaensis was given to it I am un- 

 able to explain. The only material I have seen, aside from speci- 

 mens recently received from Panay, is that which constitutes 

 the type in my herbarium. I have not received any specimens 

 from Mindanao that are referable to the Sibuyan plants. In June 

 1919 A. Martelino and G. Edano collected on Mount Sahbong- 

 bong, Capiz Province, Panay, and among other orchids they se-
