ARGOSTEMMA WALL. 
* Leaves scattering, lanceolate to oblanceolate, acute or acumi- 
nate at both ends. 
1. A. solaniflora n. sp. Biennial herb, varying up to 16 
em. high; stems solitary or several, frequently branched, dirty 
white pubescent. Leaves opposite, scattered along the entire 
stem, the pairs unequal in size, membranous, broadly lanceolate 
or oblong, base acute, apex acuminate, subglabrous on the upper 
darker green surface, yellowish pubescent along the midnerve and 
on the 7 to 8 pairs of lateral nerves, the larger ones 7 em. 
long and 2 em. wide, usually upon slender 5 mm. long pu- 
bescent petioles; stipule 3 mm. long, oblong, obtuse at apex, 
membranous. Inflorescence usually terminal, equalling or ex- 
ceeding the leaves, of a few flowered cyme; pedicels pubescent, 
subtended by bracts, about 8 mm. long; calyx cup shaped 
villous, its 5 segments acute; corolla white, rotate, united at the 
base; segments 5, ovate, slenderly acuminate, 7 mm. long, nerved, 
often strigose on the back especially along the margins toward 
the apex; stamens 5, erect, inserted upon the base of the corolla; 
filaments 2 mm. long; anthers 7 min. long, bifid at apex, linear, 
introrse, upper portion without pollen; seeds small, numerous, 
in membranous sacs, smooth, brown when mature, flattened, 5 
mm. across, irregular in shape; style barely exceeding the 
stamens; stigma entire subclavate. 
Type specimen 6211, A. D. E. Elmer, Sablan, Province 
of Benguet, Luzon, April, 1904. It inhabits damp shady 
stream banks. The nodding buds and the flowers have a 
striking resemblance to some species of Solanum.
