NEW OR NOTEWORTHY PHILIPPINE PLANTS, VIII. 175 
Apparently scandent. Branches terete, grayish, slightly striate, slightly 
zigzag, the leaf-bearing branchlets more or less densely pubescent with 
short brownish hairs. Leaves oblong, 11 to 17 cm long, 4.5 to 6.5 em 
wide, chartaceous, shining when dry, above entirely glabrous, beneath 
somewhat hirsute-pubescent with short hairs on the midrib and primary 
nerves, the apex shortly and sharply acuminate or merely acute, the base 
sagittate-cordate, the auricles broad, rounded, the sinus somewhat obtuse, 
about 1 cm deep, the auricles somewhat surrounding the stems but free 
from them; basal nerves two or three pairs, the lower pair or pairs short, 
the upper pair reaching to about the middle of the leaf, the primary 
nerves above the basal ones 3 or 4 on each side of the midrib, anasto- 
mosing, the reticulations lax; petioles pubescent, less than 5 mm long. 
Inflorescence axillary, solitary, simply racemose, the rachis 1 to 1.5 cm 
long, pubescent, the pedicels about 3 mm in length, each opposed by an 
ovate-lanceolate, acuminate bract, the lower ones 6 mm long, the upper 
gradually shorter. Flowers 4 cm long, the basal 4 mm ovoid, narrowed 
and tubular above, the tube about 16 mm long, 2 to 2.5 mm in diameter, 
the upper portion expanded, the lip pubescent, lanceolate, acuminate, 
about 2 cm long, 3 mm wide. Column very obscurely lobed. Anthers 
6,1 mm long. Fruit (immature) obovoid, 1.5 em long. 
BaBUYANES ISLANDS, Dalupiri, Bur. Sci. 10656 McGregor, August 20, 1909. 
A species manifestly allied to Aristolochia tagala Cham., but at once distin- 
guished by its differently shaped leaves, which are pubescent on the nerves beneath, 
very short petioles, dense racemes, and quite different flowers.

PISONIA Linn. 
Pisonia gammillii sp. nov. 
Arbor glabra, inflorescentiis exceptis, circiter 10 m alta; foliis oblongo- 
ellipticis, in sicco chartaceis, nitidis, breviter acuminatis; basi inaequi- 
lateralibus, acuminatis, usque ad 20 cm longis; inflorescentiis laxis, ter- 
minalibus axillaribusque; floribus hermaphroditis; staminibus 12 vel 13, 
breviter exsertis. 
_ A glabrous tree, except the inflorescence, unarmed, about 10 m high, 
the trunk 40 cm in diameter. Leaves mostly opposite, oblong-elliptic, 
ample, 17 to 20 em long, 8 to 10.5 cm wide, when dry chartaceous and 
somewhat shining, apparently somewhat fleshy when fresh, entire, the 
apex shortly acuminate, the base acuminate-decurrent, inequilateral ;
