DOUBTFUL SPECIES. 



D. suBOAENOsus, W. ^ A. Prodr. 249, is a plant from the Western Peninsula, 

 of which the flower is unknown and of which the place is therefore doubtful. It has 

 small ovate acute entire leaflets, many-flowered distiuctly-pedunded racemes, and a 

 narrow linear nearly straight glabrous many-seeded pod 3-4 in. long. 



D. SUB2BQUALIS, Grdh. in Wall. Cat. 5539, is another doubtful plant, of which 

 the flower is unknown, gathered by Wallich in Ava, which has been referred through 

 some confusion to Psoplwcarpus palustris, from which it totally differs. It has slender 

 terete woody suberect stems, with" short deflexed deciduous grey pubescence, caduc- 

 ous stipules, membranous stipellate leaflets with a few adpressed bristly hairs on both 

 sides, the end one oblong subobtase or cuspidate 4-5 in. long, many-flowered short- 

 .peduncled racemes and a 2-3-seeded ligulate flattish pod |-1 in. by ^in., thinly clothed 

 with long adpressed grey hairs, faintly depressed between the seeds.

Twining herbs, with large tuberous roots. Leaves 3-foliolate, stipeUate ; sti- 

 pules fastened aboTe the base. Flmoers rather large, lilac. Calyx teeth shorter 

 than the tube, the two upper connate. Corolla much exserted, the petals equal 

 in length; keel much incurved, but not beaked. Stamens monadelphous, the 

 upper free downwards ; anthers uniform. Ovary substipitate, many-ovuled ; 

 style long, much recurved, flattened laterally, densely bearded round the termi- 

 nal stigma. Pod square, with a distinct wing to each angle, distinctly septate 

 Iwtween the seeds. — Disteib. Species 3-4, aU tropical in the Old World.
