bracteis ovato-lanceolatis, 2 ad 2.5 mm longis, calycis segmentis 
anguste lanceolatis, acuminatis, 6 ad 7 mm longis; corolla alba, 
12 mm longa, extus leviter pubescens, tubo sursum ampliato; 
capsulis oblanceolatis, 1.5 cm longis. 
An erect branched herb 30 to 40 cm high, the younger parts 
sparingly pubescent, the branches terete, glabrous or nearly so, 
usually dark greenish when dry, the branchlets distinctly pubes- 
cent, often compressed or obscurely angular. Leaves of each 
pair equal or but slightly unequal, oblong, membranaceous, 
olivaceous, shining, 5 to 9 cm long, 2 to 3.5 cm wide, with 
numerous cystoliths, glabrous on both surfaces, the margins 
entire or very obscurely undulate, the apex obtuse to ‘subacute, 
base usually obtuse, sometimes acute ; lateral nerves about 6 
on each side of the midrib, prominent; petioles 2 to 6 mm long, 
somewhat pubescent. Cymes axillary, short-peduncled, rather 
few-flowered, the peduncles sparingly pubescent, up to 8 mm 
long. Bracts ovate-lanceolate, acuminate, 2 to 2.5 mm long, 
the pedicels 1 to 2 mm long. Calyx segments 5, narrowly lan- 
ceolate, acuminate, somewhat pubescent, 6 to 7 mm long. Co- 
rolla white, about 12 mm long, the lower 4 mm of the tube 
cylindric, about 1 mm in diameter, then somewhat inflated and 
slightly pubescent, the whole tube about 9 mm long; the larger 
lobe 4.5 mm long, about 3 mm wide, cleft, the lobules oblong- 
ovate, 2 mm long, the smaller lobe 3-lobulate, the lobules oblong 
to oblong-elliptic, obtuse, 3 mm long, the middle one slightly 
broader than the two lateral ones. Filaments glabrous; an- 
thers about 1.5 mm long, one cell attached slightly above the 
other. Capsules oblanceolate, glabrous or slightly pubescent, 
about 1.5 em long, 2.5 mm in diameter, the sterile basal part 
6 to 7 mm long. 
MINDORO, Paluan, Bur. Sci. 39761 Ramos, April, 1921. In 
dry forests at low altitudes. A single specimen collected on 
Mount Maquiling, Laguna Province, Luzon, by forestry students 
in November, 1918, represents the same species. 
A species apparently most closely allied to Hallieracantha 
aequifolia (C. B. Clarke) Merr., differing in numerous char- 
acters and readily distinguished by its much shorter petioles.
