utrinque circiter 12, tenuibus, primariis quam secundariis vix 
magis distinctis; fructibus ellipsoideis, prominente apiculatis, 
glabris, circiter 9 mm longis, seminibus solitariis. 
A scandent shrub reaching a height of about 10 m, entirely 
glabrous (flowers unknown). Branches and branchlets slender, 
terete, smooth, dark reddish-brown when dry. Leaves oblong, 
chartaceous, 7 to 11 cm long, 2.5 to 4.5 cm wide, subequally 
narrowed to the acute base and to the acuminate apex, the upper 
surface dark olivaceous when dry, shining, the lower subglau- 
cous; lateral nerves slender, not prominent, the primary ones 
about 12 on each side of the midrib, slender, anastomosing, 
scarcely more distinct than are the secondary nerves and primary 
reticulations; petioles 5 to 7 mm long. Flowers not seen, soli- 
tary, axillary, and terminal, opposed to the ultimate leaf, the 
fruiting peduncles stout, glabrous, thickened upward, up to 2 cm 
long, the persistent sepals thickly coriaceous, broadly ovate, 
glabrous, 3 to 4 mm long and wider than long, persistent. Fruits 
numerous, ellipsoid, about 9 mm long, prominently apiculate, 
brown when dry, dark purple when fresh, entirely glabrous even 
when very young, their pedicels 2 to 2.5 cm long. Seeds solitary, 
conforming to the fruit in outline but not at all apiculate. 
Palawan, Taytay, Merrill 9277 (type), May, 1913, on forested slopes, 
Taytay-Bantolan trail, altitude about 150 meters. I refer here also Elmer 
12803 from Puerto Princesa, Palawan, distributed as Unona clusiflora Merr. 
A species quite different from Dasymaschalon clusiflorum Merr., especially 
in its habit and in its vegetative characters. It is distinguished by its leaves 
being smaller, thinner, dark-colored when dry, acute, never rounded at the 
base, and by its more numerous, much less prominent nerves, the primary 
ones scarcely more distinct than are the secondary ones and the reticulations. 
MEIOGYNE Miquel 
Meiogyne was proposed by Miquel in the year 1865 s as a mono- 
typic genus, based on Unona virgata Blume Bijdr. (1825) 14. 
Meiogyne, however, was reduced to Unona by Bentham & Hooker 
f. 8 9 the same year, where it has been placed by most later authors. 
Blume himself 10 transferred it to the genus Uvaria, with which, 
however, it has little in common. Hooker f. & Thomson 11 re- 
ferred it to the genus Cananga, chiefly, apparently, because of 
its numerous 2-seriate ovules. King 12 transferred it to the genus
