about 3 mm long. Ovary ovoid, glabrous; styles 3, entire, 0.5 
mm long. Capsules subglobose, about 1 cm long. Seeds about 
6 mm in diameter. - 
PANAY, Antique Province, Culasi, Bur. Sci, 32424 McGregor 
(type), June 3, 1918, in forests, altitude about 300 meters. The 
same species is represented by Bur. Sci. 26228 McGregor from 
the vicinity of Paete, Laguna Province, Luzon, June, 1915. 
This species is not closely allied to any other known Philip- 
pine form and differs from the other species of this section 
in its axillary inflorescences. It is easily recognized by its lax 
inflorescences and its distinctly 3-nerved leaves, the basal nerves 
usually extending to near the middle of the leaf. 
TRIGONOSTEMON LAXIFLORUS sp. nov. 
Frutex, partibus junioribus et subtus foliis plus minusve pu- 
bescentibus; foliis oblongis ad oblongo-lanceolatis, circiter 25 
cm longis, perspicue acuminatis, basi acutis, nervis utrinque 
circiter 18; inflorescentiis ¢@ tenuibus, laxis, axillaribus, usque 
ad 30 cm longis; floribus paucis, longissime pedicellatis; brac- 
teis foliaceis, lanceolatis, 1 ad 1.5 cm longis; sepalis oblongis 
ad oblongo-ovatis, acuminatis, ut videtur accrescentibus, 7 ad 
11 mm longis; ovario ovoideo, pubescente; stylis 3, brevibus, 
partitis. 
A shrub, more or less pubescent. Branches terete, glabrous, 
about 4 mm in diameter, the younger parts somewhat pubescent. 
Leaves oblong to oblong-lanceolate, about 25 cm long and 7 cm 
wide, narrowed below to the acute base and above to the 
conspicuously acuminate apex, the margins obscurely and dis- 
tantly undulate-crenate, the upper surface glabrous, dark-oliva- 
ceous when dry, the lower surface paler, rather softly pubescent 
on the midrib, nerves, and reticulations, and with similar but 
more scattered hairs on the epidermis; lateral nerves about 18 
on each side of the midrib, prominent; petioles 3 to 4.5 cm long, 
pubescent when young, soon becoming glabrous. Pistillate in- 
florescences slender, lax, rather few-flowered, long-peduncled, 
pubescent, up to 30 cm long, the branches few, rather short, each 
bearing from 1 to 3 very long-peduncled flowers, the branches 
subtended by lanceolate, 1 to 1.5 cm long, leaflike bracts. Ped- 
icels 2 to 5 cm long, thickened upward, usually with a small 
linear-oblong bracteole. Sepals 5, oblong to oblong-ovate, acu- 
minate, sparingly pubescent, apparently somewhat accrescent 
and persistent, 7 to 11 mm long, 2.5 to 5 mm wide. Disk 
glabrous, with 5, rounded, orbicular-ovate lobes. Ovary ovoid, 
rather densely cinereous-pubescent; styles 3, about 1.5 mm long,
