irregular, in general oblong and about 4 mm long, somewhat 
irregularly lacerate-toothed near the apex. Anthers 5, inserted 
in the middle of the tube, included, ovate-lanceolate, acuminate, 
base rounded, about 1 mm long. Ovary 1-celled, narrowly ovoid, 
glabrous, 1 mm long, tapering into the 1 mm long style; ovules 
numerous ; stigma somewhat lanceolate, about 1 mm long, slightly 
cleft at the apex. Fruit unknown. 
Leyte, Dagami, C, A. Wenzel 100 . June 5, 1913, climbing on trees on 
forested foothills, altitude about 60 meters, the stem less than 1 cm in 
diameter. 
In some respects the floral characters are intermediate between Wil- 
loughbya and Ckilocarpus; they approach the former, however, more 
closely that the latter, and in the absence of fruit the specimen has been 
described as Willoughbya. The second species of the genus for the Phil- 
ippines.

PREMNA Linnaeus 
PREMNA MEMBRANIFOLIA sp, nov. 
Frutex scandens, partibus junioribus inflorescentiis exceptis 
glaber; foliis membranaceis, oblongis, integris, usque ad 10 cm 
longis, viridibus, nitidis, acute acuminatis, basi rotundatis vel 
subrotundatis, nervis utrinque circiter 6, adscendentibus; inflor- 
escentiis terminalibus, corymbosis, multifloris, pubescens, circiter 
6 cm diametro; calycibus pubescens, bilabiatis, 5-dentatis. 
A scandent shrub about 5 m high, the stem 1 cm in diameter, 
glabrous except the pubescent younger parts and inflorescence. 
Branchlets terete, brownish, sparingly lenticellate, about 2 mm 
in diameter. Leaves very thinly membranaceous, oblong, entire, 
8 to 10 cm long, 4 to 5 cm wide, when dry green and shining on 
both surfaces, the apex acutely acuminate, the base rounded or 
subrounded, the very young ones slightly pubescent on the midrib 
and nerves, soon becoming glabrous; lateral nerves about 6 on 
each side of the midrib, slender, distinct, curved-ascending; 
petioles slender, 2.5 to 4 cm long. Inflorescence terminal, corym- 
bose, rather densely subcinereous-pubescent with very short 
hairs, about 6 cm long and wide, many-flowered. Flowers white, 
the pedicels 1 to 3 mm long. Calyx pubescent, somewhat ovoid or 
long cup-shaped, distinctly 2-lipped, one lip 2-toothed, the other 
3-toothed, the teeth of the former considerably smaller than those 
of the latter. Corolla, including the lobes, about 6 mm long, 
glabrous outside, the tube villous within, 2-lipped, one lip with 
two lobes about 2 mm long and wide, slightly retuse, the other 
distinctly longer and much broader, with a central, suborbicular,
