obovate, about equally narrowed to the slenderly acuminate apex 
and to the acute base, 8 to 10 cm long, 3.5 to 5 cm wide, the 
margins prominently and acutely apiculate-serrate except in the 
lower 1 cm and the margins of the acumen which are entire; 
nerves 7 or 8 on each side of the midrib, distinct, anastomosing, 
the reticulations lax; petioles furfuraceous-pubescent, about 2 
mm long. Inflorescence terminal, slightly pubescent, solitary, 
including the peduncle up to 13 cm in length, each bearing one 
or two, rather many flowered, 2 to 3 em long spikes. Flewers 
white, the bract orbicular-ovate, irregularly toothed, 1.7 to 2 
mm long, rounded. Pistillate flower: Ovary narrowly ovoid, 
somewhat narrowed at both ends, about 2 mm long, glabrous. 
Staminate flowers: Antheriferous scale 3-partite, the lobes ob- 
long, rounded, the central one about 4 mm long, 1.2 mm wide, 
bearing an oblong, 1.2 mm long, 2-celled anther, the lateral lobes 
about as wide, one-half as long, each bearing a 1-celled anther.

Probably as closely allied to Chloranthus henryi Hemsl. as to any other 
species. It is distinguished, however, by its pubescent branchlets and 
lower surfaces of its smaller leaves, its inflorescence reduced to 1 or 2 
spikes, and its smaller flowers. From its closest Philippine ally, C. philip- 
pinensis Merr., it differs in its much smaller, pubescent, shortly petioled 
leaves, and its larger flowers.

ARISTOLOCHIA Linnaeus 
ARISTOLOCHIA LEYTENSIS sp. nov. 
Species A. tagala et A. mindanaensis similis et affinis, differt 
floribus multo majoribus, usque ad 8.5 cm longis. 
A slender vine, nearly glabrous, the branches brownish when 
dry, glabrous, deeply sulcate. Leaves ovate, membranaceous, 
glabrous, of about the same color on both surfaces, somewhat 
shining, 14 to 17 cm long, 8 to 10 cm wide, entire, the apex 
acuminate, the base deeply and prominently cordate, the sinus 
about 2 cm deep, 1.5 to 2 cm wide, often obovate, the basal lobes 
rounded; basal nerves 3, the lateral pair soon forked, and 
its lower branches soon forked again, the lateral nerves above 
the base about 3 on each side of the midrib, prominent, the re- 
ticulations very lax; petioles 4 to 7 cm long, glabrous. Racemes 
axillary, solitary, the rachis slender, slightly pubescent, about 
3 em long, each raceme bearing about 6 flowers, not all de- 
veloping at one time, each flower subtended by an ovate-lanceo- 
late, acuminate, slightly pubescent bract, the pedicels minutely 
.
