NEW AND RARE MALAYAN PLANTS. 13 
branched cyme, pedicels $} inch long hairy. Calyx cupular with 
lanceate obtuse hairy lobes. Corolla 1 inch across, lobes narrow 
lanceolate. Cone of stamens as long thick, shortly acuminate. 
Fruit cupular hairy. 
Johore: Ulu Sayong (Kloss); Negri Sembilan: Bukit Sulu 
(N. Cantley). “Sumpu Kring.” 
Allied to A. johorensis but much smaller. 
The leaves in the Negri Sembilan plant are broader and 
rounded at the tip. 
Argostemma enerve, N. sp. 
Stem creeping ascending 5 to 8 inches glabrous. Leaves un- 
equal, large one ovate lanceolate base rounded or slightly narrowed 
aequilateral at base, glabrous fieshy beneath glaucous nerves in- 
visible on both surfaces margin thickened 24 inches long by 1 inch 
wide, petiole + inch long, small leaf ovate cordate acute 2 t inch long. 
Stipules ane ar obtuse. Cyme solitary terminal 2-4 flowered on 
a peduncle an inch long glabrous with a circle of small bracts about 
half way up. Bracts lanceolate obtuse. Pedicels in flower 4+ inch 
long, in fruit nearly 1 inch long, white hairy. Calyx campanulate 
hairy, with short triangular teeth. Corolla white half an inch 
across lobes lanceolate acute ;4, inch across. Stamen cone as long 
narrow long acuminate curved. Capsule + inch long, campanulate 
densely appressed hairy. 
Negri Sembilan: Gunong Angsi (Feb. 1904) Ridley. 
Resembles A. johorensis and is allied to it, differing in its aequi- 
lateral leaves which are thicker, the nerves being quite invisible, 
the underside white, and its longer and more slender cone of sta- 
mens. In the fruit, form of stipules and smaller leaves it closely 
resembles A. johorensis. 
Argostemma Havilandu, n. sp. 
Stem as thick as a crow quill densely covered with corky reti- 
culations and transverse bars often elevated into flat discs. Leaves 
distinct very unequal, largest lanceolate acuminate base cuneate, 
above smooth nerves invisible drying black, beneath glaucous with 
8 pairs of nerves inarching within the margin 23-3 inches long ? 
inch wide, petiole 4 inch long, small leaf linear or lanceolate linear 
x inch long. Stipules broader lanceolate obtuse. Peduncle 1. inch 
long slender sparingly pubescent. Flowers small white umbellate 
on slender hairy pedicels + inch long, with short linear bracts at 
the base. Calyx tube short lobes ovate obtuse hairy. Corolla in 
bud ovoid obtuse lobes ovate lanceolate obtuse 4, inch long. Sta- 
men column short ovoid, anthers lanceolate broad blunt with curved 
linear appendages. 
Sarawak: Kuching (Haviland, 2958). 
Very curious in the stem which. has fawn colored elevated ridges 
with transverse bars of a corky nature which are often developed 
into flattened irregular discs. The small flowers with short petals 
and stamens are also peculiar,
