ORCHIDACE.E 



In the Philippine Islands the yellow stems of this plant are 

 used for purposes of ornamental weaving. In the economic plant 

 collection of the Bussey Institution of Harvard University there 

 is a riding whip the handle of which is covered with interwoven 

 strands taken from the stems of Dendrobium crumenatum and 

 from a species of fern, probably from Lygodium circinnatum 

 (Burm.) Sw. 



Dendrobium Schuetzii Rolf e in Orch. Rev. 19 (1911) 224; 

 in Bot. Mag. (1913) t. 8495. 



A specimen of this species from the Province of Surigao in 

 northwestern Mindanao, where it was collected in company 

 with D. Dearei Reichb. f., is in my herbarium. Although D. 

 Schuetzii was originally published without exact localization, the 

 geographical origin being given as the Philippine Islands, it is 

 now known to be a native of Mindanao. Dendrobium Sanderae 

 Rolfe, a near relative of Z). Schuetzii, is a native of Luzon, where 

 it has been found in the Province of Benguet and in Bontoc 

 Subprovince. Dendrobium Dearei is represented in my herba- 

 rium by specimens from Mindoro, and from Dinagat Island, a 

 small island just north of Mindanao.
