А TRIBE OF LEGUMINOS. 115 
ptoxima, sed folia majora, panicule minores, cum calycibus minus 
tomentelle. 
Hab. Java, Blume (Miquel, 1. c.). 
I have not seen this plant. 
Doubtful Species. 
Pongamia ovalifolia, W. et Arn. Prod. ; Wight, Ic. t. 328, from the 
Peninsula, appears from the figure to have the foliage of the Paraderris 
section, with the inflorescence and flowers rather of Euderris or Bra- 
chypterum. I have not seen the specimen, and the fruit is unknown; so 
that it is impossible to define it accurately, or to judge of its affinities. 
The Peninsula and Ceylon plants I formerly referred to it are certainly 
distinct, and are above described as Derris oblonga. 
Derris acuminata, Miq. Fl. Ned. Ind. i. p. 144 (non Benth.), from 
Java and Sumatra, and D. pubipetala; Miq. 1. c. p. 145, from Java, differ 
from all other species except D. elliptica in their silky vexillum, and 
from that one in many particulars, The fruit is unknown in both; and 
from Miquel's description I should strongly suspeet they may belong to 
Millettia. I have seen no specimens. 
Pongamia corallaria, Miq., is taken up from a rude figure of Rum- 
phius’s. Dalbergia rostrata, Hassk., deseribed by the author from leaves 
only, and which I thought might be those of Derris uliginosa, is enu- 
merated by Miquel as a species of Millettia, with a note of doubt. This 
practice of publishing species from unintelligible figures or imperfect 
specimens without flowers or fruit or other means of future identification, 
far from contributing to the advancement of science, only serves to 
bewilder and confuse. Upon this principle I have passed by some Pon- 
gamias of Wallich’s Catalogue, and other specimens, of which we have 
mere fragments, although apparently representing species of Derris 
distinet from any of the above.
