trunk, forming very dense, hemispheric masses 8 to 10 cm in 
diameter. Receptacles obovoid, often more or less compressed- 
angular by pressure of contiguous ones, 10 to 12 mm in diameter, 
green, glabrous or nearly so, the umbilicus about 3 mm in 
diameter; peduncles slender, 1.5 to 2 cm long, with three small 
bracteoles at the apex. Fertile female flowers numerous, their 
pedicels up to 1.5 mm in length; perianth short, sheathing the 
pedicel below, truncate, about 1 mm long. Ovary ovoid, 1.5 
mm in diameter; style lateral.

A species manifestly closely allied to Ficus rubrovenia Merr., and very 
similar to that species, differing in its somewhat appressed-hirsute, not 
glabrous, branchlets, and its very coarsely lobed-toothed, not merely undu- 
late leaves. 
FICUS RIVULARIS sp. nov. § EHusyce. 
Frutex circiter 4 m altus ramulis minute puberulis exceptis 
glaber ; foliis alternis, lanceolatis vel anguste lanceolatis, leviter 
falcatis, usque ad 25 cm longis, utrinque angustatis, apice longe 
tenuiter caudato-acuminatis, basi acutis, integris, subcoriaceis, 
laevis, subtus albido-punctatis, nervis utrinque circiter 20; recep- 
taculis axillaribus, solitariis, obovoideis, 1 ad 1.5 cm diametro, 
pedunculatis, bracteis circiter 2 mm longis. 
An erect, nearly glabrous shrub about 4 m high. Branches 
terete, slender, reddish-brown, glabrous, the younger branchlets 
somewhat puberulent. Leaves alternate, subcoriaceous, lanceo- 
late to narrowly lanceolate, 12 to 25 cm long, 1.5 to 3 cm wide, 
somewhat falcate, narrowed at both ends, the apex very slenderly 
caudate-acuminate, the acumen up to 4 cm in length, minutely 
apiculate, the base equilateral, usually acute, rarely slightly 
obtuse, minutely cucullate on the upper surface, the margins 
quite entire, somewhat revolute, the upper surface smooth, gla- 
brous, shining, rather pale or somewhat olivaceous when dry, 
the lower surface somewhat paler, or brownish, distinctly white- 
puncticulate under a lens; lateral nerves about 20 on each side 
of the midrib, rather distinct, anastomosing, the ultimate retic- 
ulations distinct, angular, about 1 mm in diameter; petioles 5 
to 10 mm long; membranaceous, deciduous, linear-lanceolate or- 
narrowly lanceolate, acuminate, 1.5 to 2 cm long. Receptacles 
axillary, solitary, obovoid, 1 to 1.5 cm in diameter, glabrous, 
somewhat narrowed at the base into a very short pseudo-stalk, 
their peduncles slender, 5 to 10 mm long, with three, ovate, 
obtuse, 2 mm long bracts at the summit. Gall flowers very num- 
erous, in general obovoid, sessile or shortly pedicelled, about 2.5
