RYPAROSA Blume 
RYPAROSA ACUMINATA sp. nov. 
Arbor, ramulis adpresse hirsutis, inflorescentiis $ elongatis, 
dense adpresse ferrugineo-hirsutis ; foliis oblongis, subcoriaceis, 
tenuiter acute acuminatis, usque ad 22 cm longis, basi acutis, 
subtus pallidis, nervis utrinque 3 vel 4, curvato-adscendentibus, 
prominentibus ; racemis $ axillaribus, solitariis, usque ad 30 cm 
longis, floribus numerosis, breviter pedicellatis, sepalis petalisque 
circiter 3 mm longis. 
A tree, the branchlets and the leaves on the midrib and lateral 
nerves on the lower surface appressed-hirsute, the staminate 
racemes densely ferruginous appressed-hirsute. Leaves oblong, 
subcoriaceous, 12 to 22 cm long, 3.5 to 7 cm wide, the upper 
surface pale-olivaceous, smooth, shining, the lower pale, sub- 
glaucous, the base acute, the apex slenderly and acutely acum- 
inate, the acumen 1 to 2 cm in length; lateral nerves 3 or 4 
on each side of the midrib, prominent, curved-ascending, the 
reticulations distinct; petioles 1 to 1.5 cm long. Male racemes 
axillary, solitary, 15 to 30 cm long, apparently floriferous 
throughout, but the lower flowers caducous. Pedicels pubescent, 
about 1.5 mm long. Sepals three, elliptic-ovate to elliptic, 2.5 
to 3 mm long, appressed ferruginous-hirsute. Petals 5, mem- 
branaceous, oblong-ovate, acute or somewhat acuminate, some- 
what pubescent, the basal scale densely ciliate, about 1 mm in 
diameter. Staminal column glabrous, 2.5 to 3 mm long, slender, 
somewhat thickened upward ; anthers five, 1 mm long, forming a 
depressed-globose head. 
Sarawak, Baram District, Miri River, Hose 501, January, 1905. 
The second species of the genus to' be reported from Borneo, readily 
distinguished from the other described forms by its slenderly and sharply 
acuminate, few-nerved leaves. Hose 430 possibly represents Ryparosa longi- 
pedunculata Boerl., a Javan species, but the flowers are quite too young to 
warrant a definite determination of it.

The above specimens are apparently referable to Capitaine’s variety, 
which is here transferred to Rinorea anguifera. Medusa anguifera Lour., 
FI. Cochinch. (1790) 406, supplies the oldest specific name for the species.
