New Guinea and the Bismarck Archipelago. 
There are apparently several other species of the genus represented in the 
materials before me, but most of the forms not classified are represented by 
flowering specimens only. As it is practically impossible in many cases definitely 
to determine, in the absence of fruit, whether the plant being dealt with is a 
Derris or a Millettia, I have refrained from describing any of these forms, with 
the hope that eventually additional material will be secured that will enable 
us satisfactorily to place the forms now represented only by flowering specimens. 
The generic name Derris Lour. (1790) is here retained in accordance with the 
list of nomina conservanda of the Vienna Botanical Congress. O. Kuntze has 
referred all the species to Pterocarpus, and Taubert has adopted the genus Deguelia 
Aubl. (1775). Two other earlier names are Salkan Adans., and Solori Adans. 
(1763), the latter two being synonyms of Derris, as shown by Prain, and not 
referable to Dalbergia, where they have been placed by most authors. 
DOUBTFUL AND EXCLUDED SPECIES. 
DERRIS DISCOLOR Benth.; Ceron Cat. Pl. Herb. (Manila) (1892) 67. A species 
of doubtful status from Sikkim and Silhet. The Philippine record is probably 
due to an erroneously identified plant; it was based on a specimen from Balabac 
Island, Vidal 2665. 
DERRIS FERRUGINEA Benth.; Ceron 1. ¢. 66.. The Philippine record is based on 
Vidal 2576 from the Province of Isabela, Luzon, a specimen of which is in the 
Kew Herbarium; this specimen is very similar to D. mindorensis Perk., but is 
slightly more pubescent. Material collected in Mindanao, Bolster 356, 406, in- 
sufficient for accurate identification, may be the same as Vidal’s specimen. 
Whether or not the Philippine material is referable to D. ferruginea Benth., T am 
unable to determine at present. That species is supposed to extend from the 
eastern Himalayan region to Burma. See D. mindorensis Perk., above.
