Tn my Flora Montana Formosae I doubtfully referred this plant to C. 

 Wightiani. After examining more carefully, I have found that the speci- 

 men is the same as the Philippine form of C. Lesclienaultiana DC. The 

 present plant differs from C. IVigldiana in having fusiformed achenes and 

 thread-like filaments. C. LescJtenanItiana described in KUNTZE'S " Mouog. 

 Clemat. p. 107," has lanceolate leaves, while the Fornmsan plant lias ovate 

 ones.
