By H, N. Ridley, C.M.G., F.R.S., late Director of Gardens, S.S. 



DiPLOSPORA LASIANTHA, Sp. UOV. 



A shrub, branches slender, brown-velvety; leaves lanceolate 

 to elliptic lanceolate, slightly oblique, shortly cuspidate, shortly 

 narrowed at the base, 14 cm. long, 3.5 cm. wide; above, 

 subglabrous, not polished except the midrib and margins, 

 which are hairy ; beneath dotted over with hairs, nerves 

 8 pairs, slender, ascending, midrib hairy ; petiole, 5 mm. hairy. 

 Stipules lanceolate acuminate, velvety hairy. Flowers, 3-4 

 sessile, axillery. Calyx velvety with short obtuse lobes. 

 Corolla 4 mm. long, tube short, lobes four ovate, acute, all 

 hairy except the glabrous inner face of the lobes. Stamens 

 exsert in a cone from the mouth of the tube, hairy. 



A very distinct plant in its small leaves and hairy corolla. 



Argostemma tenue, sp. nov. 



A succulent herb with a basal tuber, stem 6-10 cm. long, 

 slender; leaves subterminal3, one lanceolate long acuminate, 

 base cuneate, thin, glabrous, pale beneath, 14 cm. long, 2.5 cm. 

 wide, very shortly petioled, nerves very fine, ten ; two below 

 it, small unequal lanceolate obtuse, 8-10 mm. by .2 to 4 mm. 

 Panicle lax, base, 2.5 cm. wide, bracts short foliaceous 4 mm. 

 long. Branches slender. Calyx short campanulate, with 

 rather large 4-lobed limb. Corolla lobes 4, lanceolate acu- 

 minate 4 mm. long, very narrow. 



Stamens very narrow, forming a narrow elongate cone as 

 long as the corolla, long beaked. 



Ne-dv A. verticillatum, but the leaves are reduced to one 

 long and two very small ones, and the inflorescence and 

 flowers are very much smaller.
