A plant of this pretty, evergreen climber was sent to 
Kew from Hong Kong, in 1900, by Mr. C. Ford, I.8.0., 
under the name of Derris Fordii, Oliv. He also sent pods, 
containing imperfect seeds, bearing the same name. It 
was taken for granted that Mr. Ford was familiar with 
the D. Fordii, Oliv. (Hook. Ic. Pl. t. 1771), as it was 
founded upon specimens supplied by him. Last August 
the plant now figured flowered profusely in the Palm 
House, where it covered some square yards of the roof, 
and it proved to be a different species from D, Fordit, but 
identical with specimens in the Kew Herbarium from 
Hainan, collected by Dr. A. Henry (8228 and 8394). 
Another Chinese species of Dervis, from Kwantung, 
identified by the late Dr. Hance with D. oblonga from 
Aprit Ist, 1905,
