1 NEW AND RARE MALAYAN PLANTS. 
an inch acTOSs tube very short, lobes very narrow lanceolate linear 
acuminate j'5 inch across at the base white. Stamens in a fairly 
stout acuminate cone as long as the petals. Fruit shortly cupular 
* inch long densely hairy. 
Johore: Tempayan river (Ridley 13270), Sungei Tebrau 
(13207), Mt. Austin; Serom near Batu Pahat.. In low wet forest. 
Apparently confined to South Johore. Distinct in its long 
stem with elongate internodes, often an inch long, narrow corolla 
lobes and hairy capsule. 
A. johorense var. Kelsalli. 
Stems shorter and leaves more crowded, hairy. Leaves lan- 
ceolate subacute base rounded marginal above glabrous nerves visible 
7 pairs, 24 inches long, 14 inch wide, beneath paler nerves elevated 
covered with spreading faite) and scattered hairs between, small 
leives orbicular, glabrous, petiole x inch long hairy. Cymes few 
flowered. Calyx as in type. Corolla lobes slightly broader and 
shorter. Fruit as in type. 
Selangor: Bukit Hitam (Kelsall). 
I hardly care to distinguish this specifically though it differs 
in its hairiness and pale underside of leaf. The hairs are rather 
coarse thick trichomes thickened at the base and narrowed upwards. 
Argostemma denticulatum, n. sp. 
The whole plant twelve inches tall, stem succulent, with inter- 
nodes one inch long. Leaves fleshy lanceolate acuminate narrowed 
at the base, margins minutely denticulate towards the tip, paler 
beneath gious except for a few scurfy hairs on the midrib be- 
neath, 3 to +4 inches long, half to one inch wide, opposite leaf very 
small oblong ovate ;45 inch long, caducous, petiole a quarter of an 
inch long, with several linear bracts at the base, and also at the 
base of the cyme, ;'5 inch long. Flowers about 9 in a compound 
cyme; pedicels 4 inch long. Calyx lobes ovate lanceolate acu- 
minate,;', inch long. Corolla lobes reflexed triangular acute § inch 
long white. Staminal cone } inch long rather abruptly acuminate. 
Selangor: Ginting Sempah, 3990 feet alt. In thick forest. 
This species is allied to A. lanceolatum, Ridl., but is quite 
elabrous, the margins of the leaves minutely denticulate, the oppos- 
ing leaf smaller, and the flowers fewer and smaller. 
Argostemma Klossu, n. sp. 
A dwarf plant 4-5 inches tall, stem hairy, internodes short. 
Leaves unequal, larger one elliptic lanceolate acute or subacute base’ 
rounded ineequilateral above glabrous or sprinkled with hairs, 
back white nerves hairy, and hairs sprinkled over it, 2 inches long 
4 inch wide, petiole ;'5 inch long, hairy, small leaf ovate cordate 
4 inch long. Stipules orbicular rounded, wider but shorter. Pe-
