Western Szech'uan: valley of Tung River, alt. 700 m., May 1904 (Veitch 

 Exped. No. 4063, type). Yunnan: Yuan-chiang, alt. 1150 m., A. Henry (No. 

 13303]. 



This species belongs to the section Danzleria Hiern and is very different from any 

 other recognized species from China. It appears to us most closely related to D. 

 cordifolia Roxburgh (D. montana, ^ cordifolia Hiern), which has leaves usually 

 more or less cordate at the base, longer petioles and peduncles, tetramerous flowers, 

 differently shaped calyx-lobes and corolla and a glabrous ovary. 



This new species is a rare plant in western Szech'uan and has been seen on only 

 one occasion.

 funde 4-partitus lobis ovato-lanceolatis acuminatis erectis 3 mm. longis adpresse

Yunnan : Szemao, forests, alt. 1300-1600 m., A. Henry (Nos. 12984 , 12984 4, 

 9, 13288, fruit, type); Mengtsze, mountains southwest, alt. IBtHrTm., A. Henry 

 (No. 10938). 



This species belongs to the section Danzleria Hicm, and is apparently dis- 

 tinct and not closely related to any other Chinese species. It is characterized 

 by its thin glabrescent, short, petiolate leaves which dry black, by its very short- 

 peduncled tetramerous flowers, by the spreading, narrow calyx-lobes in the female 

 flowers and by its small glabrous fruit. It may be compared with D. mollifolui 

 Rehder and Wilson, described above, which is perhaps its nearest ally.
