China : Kweichau ; Le Mans Ilerharium, 226. 



There are two slieets of this species in the Le Mans Herbarium, 

 kindly lent for detcrniination, but the specimens are all so fragmentary 

 that I have been obliged to remove, moisten, and analyse many flowers 

 to determine approximately the form, etc. of their organs. No 

 Iiabitat is attached to either sheet, one of whicli bears a ticket inscribed 

 * No, 226, fleur bleu violette; gousse longuc.' — J. D. Hooker.
