the same color on both surfaces, entire or obscurely repand above, the 
apex rather abruptly acuminate, the base usually broad, rounded or sub- 
truncate, and with two glands either on the margins at the juncture with 
the petiole, or on the petiole itself ; basal nerves 5, the outer shorter pair 
from the very base of the leaf, the inner and longer more prominent pair 
leaving the midrib a short distance above the base and extending to 
beyond the middle, the lateral nerves above the basal ones two or three 
on each side of the midrib, ascending, prominent, anastomosing, the 
reticulations distinct, rather lax; petioles 2.5 to 4.5 cm long. Bacemes 
in the upper axils, solitary, in flower 2.5 to 3.5 cm long, few-flowered, in 
fruit somewhat longer, densely gray-pubescent, the pedicels 5 to 8 mm 
long, longer in fruit. Petals and sepals scarcely distinct, and irregularly 
arranged, the sepals 4 or 5, ovate, acute or slightly acuminate, 10 mm 
long, 6 mm wide, densely pubescent outside, strongly imbricate, the outer 
two or three entirely free, the inner two or three more or less united 
with the petals and usually staminiferous ; petals 10 to 15, similar to the 
sepals, and like them densely gray-pubescent, of equal length but narrower, 
gradually narrower inwards, the innermost ones linear and only 1 to 1.5 
mm wide, all more or less imbricate and all connate below. Stamens 
indefinite, inserted on the base of the petals and on the inner sepals; 
filaments very slender, elongated, very slightly united at the base, 6 to 
10 mm long; anthers minute, longitudinally dehiscing, less than 0.5 mm 
long. Ovary free, densely gray-pubescent, slightly stipitate, ovoid or 
ellipsoid, narrowed at both ends, 1-celled, with 5 parietal placentae, each 
bearing numerous ovules; style simple, terminal, glabrous or slightly 
pubescent at the base, 2 to 4 mm long; stigma minute, subdisciform or 
obscurely 3-lobed, not larger than the st}de. Fruit crustaceous, indeliis- 
cent, ovoid or ellipsoid, 1.5 to 2 cm long, apiculate, densely gray-pubes- 
cent, obscurely longitudinally ribbed ; seeds many, obovoid, often irreg- 
ularly compressed, black, shining, the testa crustaceous, the albumen 
fleshy. Barely flowers are found with an imperfect ovary which is nearly 
glabrous, and contains no ovules.

November, 1907, in forests at an altitude of about 600 m, in flower: Province 
of Rizal, Bosoboso, For. Bur. 2005 Ahern’s collector, November, 1904, with nearly 
mature fruits: Province of Bataan, Lamao River, Williams 531, January, 1903,

This new genus is somewhat anomalous, but seems to be most closely allied 
to Oncoha Forsk., differing in its hermaphrodite flowers, its inner perianth lobes 
smaller than the outer ones, the stamens slightly united and inserted on the 
petals and sepals, its racemose inflorescence, etc. In its perianth characters 
it seems also to approach Pyramidocarjms Oliver, of Africa, but is quite different 
from that genus in other floral characters. 
The above new genus is dedicated to Major George P. Ahern, Director of 
Forestry for the Philippine Islands, in commemoration of his active interest in, 
and strong support of botanical investigations in the Archipelago during the 
past nine years.
