Argostemma reptans, n. sp. 
A dwarf plant 2 to 3 inches tall with a slender creeping rhizome 
emitting stems at intervals and often forming small tufts in cracks 
in rock. Stems slender corky. Leaves unequal, larger ones lan- 
ceolate subrhomboid equally narrowed to both ends subcoriaceous, 
margins crenulate with short teeth on each crenulation quite gla- 
brous, above grey when dry with the midrib prominent, and “the 
eas usually invisible, beneath a but brown, $-? inch long, 
+ inch wide or less, petiole short 45 inch long; smaller leaf narrow 
Gear lanceolate 1 inch long resembling the stipules, entire. 
Flower solitary terminal on a peduncle 2 = inch long with two very 
small linear, lanceolate bracts half way up. Sepals lanceolate 
acuminate + inch long. Corolla white # inch across, tube very

Kedah: on Gunong Jerai on rocks in the stream near the top 
alt. 3000 feet, June 1893. 
I do not know any species much resembling this pretty little 
plant, the corky transversely wrinkled stem, and the peculiar leaves 
make it very distinct. In some the nerves are quite invisible, in 
others four pairs can be seen, the margin is also sometimes more 
serrate or dentate than crenulate and in one or two leaves I find 
two or 3 sete on the upper midrib.
