Argyreia purpuricarpa Elm. n. sp. 



A shrubby climber; stem twining, numerously branched 

 toward the top, terete, 2.5 cm. thick, flexible; wooddy tissue 

 very soft, porous, without odor or taste, white except the 

 reddish brown central mass; bark relatively thick, dull brown 

 and scaling in dry irregular plates, fibrous, latericius except 

 the epidermis; branchlets forming dense interlaced masses, 

 smooth, yellowish brown and puberulent on the younger ones, 

 the leaf bearing short tips densely cinereous and nearly erect. 

 Leaves horizontal, alternatingly crowded, leathery, dark green 

 above and strigose in the young state but soon bearing glab- 

 rous, elliptic or obovately elliptic, entire, broadly rounded 

 at apex, base broadly obtuse or obtusely rounded, the large 

 lamina, 12 cm. long by 7 cm. wide at the middle, frequently 

 smaller, the nether side slenderly strigose at least in the 

 younger leaves, very unequally brown on the two sides in 

 the dry state; petiole 2 cm. long, oppressed pubescent, grad- 

 ually thickened toward the buse; midrib very prominent 

 beneath especially toward the base, similarly canescent, gla- 

 brous and fluted on the upper leaf surface; lateral nerves 

 5 to 7 pairs, comparatively minute, ascending and gradually 

 curved toward the distal ends, equally visible from both sides, 

 reticulations none. Fruits ascending, solitary from the leaf 

 axils; peduncle 1 cm. long at least, stout, subsulphureus 

 pubescent, easily falling and leaving large excrescent scars, 

 persistent, nearly livid us and glabrous on the inner side, 

 covered externally with oppressed yellowish gray hairs, the 

 outer of the 4 to 5 segments larger and a trifle thicker, 

 2 cm. long by 1.25 cm. wide below the middle or smaller, 

 acute to acuminate, the short apical points frequently reflexed, 

 ovate to ovately oblong, deeply concavo convex at or below
