14 NEW AND RARE MALAYAN PLANTS, 
Argostemma salicifolium, n. sp. 
Stems to peduncle 8 inches rarely branched, erect hardly creep- 
ing at base as thick as a crow quill glabrous below hairy above, 
nodes close. Leaves lanceolate long acuminate very narrow 6 inches 
long 2 inch wide base shortly cuneate, nerves 20 pairs hardly or 
not visible above, above smooth glabrous keel elevated, beneath pale 
when alive, midrib hairy; small leaves ovate cordate = inch long. 
Stipules oblong obtuse longer and narrower than the small leaf. 
Cyme compound much shorter than the leaf, peduncle slender half 
an inch, glabrous with a whorl of bracts at the base of the branches, 
two bracts linear or lanceolate linear very narrow two ovate obtuse. 
Cyme branches 2 or 3 very slender glabrous, with three small white 
flowers on pedicels + inch long. Calyx short globose campanulate, 
lobes ovate acuminate glabrous. Corolla lobes broad lanceolate } 
inch long, white. Stamens lanceolate in a thick acute cone about 
as long as the petals hardly appendaged. Fruit $ inch long globose 
campanulate glabrous. 
Borneo: Sarawak on Matang (Hullett, Ridley 11751). 
A very distinct plant with the habit of A. Curtisii, King. 
OPHIORRHIZA. 
This genus of herbs occasionally slightly woody is undoubtedly 
a difficult one, as the species seem to run into each other and requires 
careful working up from a large series of Hast Indian specimens. 
They are very abundant and conspicuous all over the Malay Penin- 
sula in deep forest, or on forest rocks. A large number have been 
described from India and the Malay islands, and ten from the 
Malay Peninsula in the Materials. Most of these latter are toler- 
ably distinct but I have not seen O. fasciculata, Don. or types of 
QO. Kunstleri, King. 
~ O. Mungos, L. the type of the genus, is described by King as 
occurring in all the provinces common and variable in size and 
pubescence. The type was described from Ceylon, and I have a 
plant collected there by myself, in fruit, which is undoubtedly 0. 
Mungos, but I have not seen anything actually lke this or agreeing 
with the description of the type in the Peninsula. 
O. discolor, Br. Wall. Cat. 6232a is readily identified alive 
at least by its deep brown leaves. 
O. erubescens, Wall. 6233, is based on a plant from Ava, with- 
out flowers, and King describes it from Perak. What I take to be 
his plant:is one of the biggest in the Peninsula, but if I am correct 
in my identifications the leaves are by no means always glabrous, the 
nerves being minutely mealy pubescent in many plants. The 
flowers are commonly pink, but occasionally white. I include under 
this the following specimens. 
Selangor: Kwala Lumpur (Curtis), Batu Caves (8238, 8585), 
Ginting Peras (7403) ; Perak: Lenggong (14477), leaves glabrous, 
flowers pink, fruit large; Pahang: Kota Glanggi (flowers white) ;
