ORCHIDACE^ 



Structurally the specimens on which my description is based 

 appear to belong to Omcea. From Omcea micrantha Bl. they differ 

 in the several flowered inflorescence. The floral structure, how- 

 ever, is very similar to that of Blume's species. The general habit 

 of the plants suggests Microsaccus Wenzelii, but the leaves are 

 much narrower perpendicularly and not so crowded. From dried 

 specimens the leaves appear to have been deeply sulcate both 

 above and beneath.

92. ASCOCENTRUM Schltr. 



Dr. R. Schlechter has proposed the new genus Ascocentrum 

 to receive those species which are allied to the following spe- 

 cies formerly ascribed to Saccolabium: S. aurantiacum Schltr., 

 S. curvifolium Lindl., S. ampulaceum Lindl., and S. miniatum 

 Lindl. Saccolabium as at present understood is closely related 

 to Sarcochilus, from which genus it is distinguished chiefly by 

 the footless column. In the Philippines Saccolabium is repre- 

 sented by*?, confusum Ames, S. luzonense Ames, S. sarcochiloides 

 Schltr., and S. Vanoverberghii Ames.
