and in dried specimens the only trace of coloration retained is 



the characteristic brownish marking found on the labellum of 



Ccelogyne sparsa and several other species of the § Lentiginosae. C. 



Loheri Rolfe (Kew Bull. 1908, 414) appears to be a closely related 



species, but the leaves are much narrower in proportion to their 



length and the disc of the labellum is traversed by five carinas.

39. DENDROCHILUM BL 



Only two other Philippine orchid genera are richer in species : 

 Bulbophyllum with eighty-six and Dendrobium with eighty- 

 three. Dendrochilum has sixty-nine species. 



Dendrochilum bistortum J. J. Smith from Maschate Island has 

 been referred to the Philippines. I have not seen any Philippine 

 specimens that match it. 



Dendrochilum cucumerinum Reichb. f. I know only from cul- 

 tivated specimens. I have not seen any specimens of authentic 

 Philippine origin. 



Dendrochilum grandiflorum Schltr. is known to me only by 

 the description and a flower from the type. 



Dendrochilum longifolium Reichb. f. has been referred to the 

 Philippines by Kranzlin ( Jagor 680), but I have not seen Jagor's 

 specimens.!), longifolium was not originally described from Phil- 

 ippine material. 



Dendrochilum maleolens Kranzl. I know only from the de- 

 scription. 



Reference should be made to Orchidace^e, volume 2, for 

 detailed synonymy and descriptions of Philippine species of Den- 

 drochilum, and for a key to the species described up to 1905. 



At the present time not less than one hundred and forty spe-
