A small, erect, slender, much branched plant 10 to 20 cm high, 
most parts more or less ferruginous-furfuraceous. Leaves nu- 
merous, linear, 1.5 to 4 cm long, 2.5 to 6 mm wide, obscurely 
undulate, equally narrowed to the acute base and the somewhat 
acuminate apex, the upper surface dark-olivaceous when dry, 
the lower pale, ferruginous-furfuraceous; nerves about 6 on each 
side of the midrib, reticulations obsolete; petioles 2 to 5 mm 
long ; stipules pubescent, linear-lanceolate, acuminate, 3 mm long. 
Flowers terminal, solitary, their pedicels about 2 mm long, the 
bracteoles linear, 2 mm long. Calyx-tube somewhat globose, 
the teeth linear, 1 mm long. Corolla-tube cylindric, 3 mm long, 
the lobes oblong, obtuse, about 2 mm in length. Fruit com- 
pressed, about 3 mm long and 5 mm wide, somewhat ferruginous- 
furfuraceous.

A very striking species, characterized by its very narrow leaves, solitary 
flowers, and ferruginous-furfuraceous indumentum. 
ARGOSTEMMA Wallich 
ARGOSTEMMA STENOPHYLLUM sp. nov. 
Planta parva, erecta, simplex, 8 ad 12 cm alta; foliis lanceo- 
latis ad oblanceolatis, chartaceis, in siccitate subnigris, usque 
ad 6 cm longis, obtusis vel acutis, leviter furfuraceis; floribus 
solitariis vel binis, 5-meris, circiter 8 mm longis, sepalis obtusis, 
petalis longe acuminatis. 
A small, erect, unbranched plant 8 to 12 cm high, the stems, 
lower surface of the leaves along the midrib, and pedicels some- 
what furfuraceous-pubescent. Leaves lanceolate or oblanceolate, 
chartaceous, dark-colored when dry, 2.6 to 6 cm long, 2.5 to 7 
mm wide, narrowed at both ends, the apex obtuse or acute, base 
acute or decurrent-acuminate, the lower surface a little paler 
than the upper, lateral nerves up to 10 on each side of the 
midrib, not prominent; stipules oblong-ovate, about 3 mm long; 
petioles 2 to 4 mm long. Flowers 5-merous, terminal and in the 
upper axils, white, solitary or in pairs, the pedicels 5 to 15 mm 
long, often elongated in fruit. Calyx outside rather densely 
pilose, including the teeth 4 mm long, the teeth oblong, obtuse, 
about 2 mm long. Corolla-lobes lanceolate, long-acuminate, 6 
mm long, slightly pilose. Anthers yellow, 6 mm long. 
Luzon, Province of Laguna, San Antonio, Bur. Sci. 20566 Ramos, March 
10, 1913, on rocks along the river. 
A species allied to Argostemma wallichii Walp. and A. solaniflorum 
Elm., distinguished, however, by its very narrow leaves.
