MERRILL. 
matic, woody rootstocks, the stems brown, angled and sulcate 
when dry, with about 5 nodes. Leaves 4, whorled at the apex 
of the stem, membranaceous, broadly obovate, 12 to 15 cm long, 8 
to 9 cm wide, slightly shining, the lower surface paler than the 
upper one, the apex prominently and sharply acuminate, the base 
acute, margins sharply and rather finely serrate, the teeth more 
distant below, the basal margins quite entire ; nerves about 9 on 
each side of the midrib; petioles about 1 cm long. Inflorescence 
terminal, about 15 cm long, slender, the peduncle about 7 cm long, 
the branches opposite, usually 4 in two pairs, the lower ones about 
6 cm long, the internode 2 cm long or less. Anther-scale about 
2.5 mm long, divided nearly to the base into three lobes, the 
lateral lobes a little shorter than the middle one, oblong, obtuse, 
the middle one with a 4-locellate anther, the laterial ones with 
2-locellate anthers ; anthers about 1 mm long, half as long as the 
lobes or less. Fruit unknown. 
Luzon, Province of Cagayan, Abulug River, Weber 1582, January, 1912, 
growing in forests, altitude about 250 m, the roots said to be fragrant, and 
the fruits white, although none of the latter were preserved. 
A species manifestly closely allied to Chloranthus henryi HemsL, of 
China, apparently differing chiefly in its smaller flowers, which are about 
one-half as large as in Hemsley’s species. In habit, general appearance, 
vegetative characters, etc., the Philippine plant very closely matches a 
specimen in the Herbarium of the Bureau of Science, representing 
Chloranthus henryi Herns!., collected by Farges in Su-tchuen; the only dif- 
ference appears to be in the flowers. I had at first determined the Luzon 
plant to be the same as Chloranthus oldhami Solms-Laub., a species known 
only from Formosa, and of which the flowers are unknown. That species, 
however, is described as having its leaves subsessile, which does not apply 
to our plant, nor are the leaves of our species crenate-dentate throughout, 
the lower 2 to 4 cm of the margins being quite entire.

A shrub about 2 m high, the branchlets, petioles, and the lower 
surface of the leaves, especially on the nerves, rather promi- 
nently villous with rather short, pale, spreading or somewhat 
appressed hairs, the older branches terete, glabrous or nearly
