DiSTEiB. China and Indo-China. 



Obsekv. Covered by yellowish soft hairs ; leaves trifoliolate, 

 petioles 5 cm. long, leaflets ovate acute 8 cm. long, 3.J- cm. broad, 

 obscurely dentate or nearly entire, lateral leaflets oblique at the 

 base ; panicles few -flowered, peduncles 4-5 cm. long ; sepals 4, 

 ovate, nearly acute, with yellowish soft hairs on the outside, 

 glabrous inside ; stamens many, 12 mm. long, filaments hairy on 

 the margin and outside, quite glabrous on the inside, anthers 

 narrow, glabrous ; achenes hairy, fusiform with two distinct ridges, 

 tails with long hairs. 



In my Flora Montana Formosge, I doubtingly referred this 

 plant to C. Wightiana. After examining more carefully, I have 

 found that the specimen is the same as the Philippine form of 

 C. LeschenauUiana DC. The present plant differs from C. Wightiana 

 in having fusiformed achenes and thread-like filaments. C. 

 LeschenauUiana described in Kuntze's " Monog. Clemat. p. 167," 

 has lanceolate leaves, wliile the Formosan plant has ovate 

 ones.

 serrate ad acumen integro, petiolulo 1 cm. longo, foliolis lateralibus 

 oblongo-ovatis acutis basi oblique rotundatis, petiolis foliorum 6 cm. 

 longis. Flores sœpe solitarii, vel paniculati, paniculis 2-3-floratis,
