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, 

 soiTiewhat 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 cm 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, 1913, 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.
