There are apparently several other species of tlie 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 fonns, with 

 the hope tliat 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. 0. 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 sjTionyms of Derris, as shown by Prain, and not 

 referable to* Dalbcrgia, wliere they have been placed by most authors. 



DOUBTFUL AND EXCLUDED SPECIES. 



Derris discolor Benth.; Ceron Cat. PI. 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. c. 06. 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- 

 suflicient for accurate identification, may be the same as Vidal's specimen. 

 Whether or not the Philippine material is referable to D. ferruginea Benth., I am 

 unable to determine at present. That species is supposed to extend from the 

 eastern Himalayan region to Buima. See D. inindorrnsis Perk., above.
