 tia. Sepalum dorsale valde concavum, in caudam filiformem con- 

 tractum, totum sepalum cum cauda usque ad 8 mm. longum, 

 margine longe hirsuto, extus vix puberulum, infra caudam con- 

 cavo-ovatum. Petala lineari-triangularia, circiter 5 mm. longa, 

 margine pubescente flavido et hirsuto, ad apicem in caudam seti- 

 formem, elongatam, producta. Labellum linguiforme, insequali- 

 ter crescentiforme a latere visum, carnosum, obtusum, glabrum, 

 circiter 3 mm. longum. Gynostemium 1.5 mm. longum, in pedem 

 2 mm. longum productum, antice bialatum alis utrinque in 

 lobum obtusum productis. Anthera integerrima. 



Except for the color of the flowers, similar to Bulbophyllum 

 Cumingii. The arms of the column are very short, hyaline, and in 

 dried specimens membranaceous, and very obtuse. The hairs on 

 the upper sepal attain a length of 2 mm. The elongated seti- 

 form tips of the upper sepal, which is about 2 mm. long with sev- 

 eral hairs originating from it, suggests B. trisetuvi, but from that 

 species the details of the column easily separate B. stramineum. 

 Palawan, Lake Manguao, E. D. Merrill 9567, May, 1913. Epiphytic on 

 mangrove trees and on dry forest slopes up to 500 meters. Flowers deep 

 straw yellow.
