ORCHIDACE.E 



Leyte, Dagami, C.A. Wenzel 0182, August 22, 1913. Epiphyte in for- 

 est, 60 meters above sea level. Palawan, Luzon. 



76. SARCOCHILUS R. Br. 



Of the nine species known to be natives of the Philippines, six 

 are endemic. By some authors Sarcochilus and Thrixspermum 

 have been regarded as congeneric. The modern tendency is to 

 keep them distinct. The chief difference between them is found 

 in the labellum, which in Sarcochilus is movably articulated with 

 the column, while in Thrixspermum it is rigidly attached. The 

 sac of the labellum in Thrixspermum has a wide opening, and 

 is not, as a rule, terminated by a more or less porrect anterior 

 utricle. 



Although Sarcochilus calceolus Lindl. was originally reported 

 as a Philippine plant, I have not included it in this list, as there 

 is an element of doubt about it. S. calceolus is common at Singa- 

 pore, and it is not improbable that the Cuming plant described 

 by Lindley was collected there and not at Manila. 



Sarcochilus compressus Reichb. f. in Walp. Ann. 6 : 498 has 

 been reported from the Philippines. 



Sarcochilus croceus Lindl. in Bot. Keg. (1846) 32 : sub t. 19 

 was described from a single leaf and a flower bud sent to Lindley 

 by Messrs. Loddiges. I have been unable to recognize it among 

 the specimens I have examined.
