PHILIPPINE PHYLLANTHINJE. 85 



minutely tubereulate ; staminal column extremely short, the filaments 

 united, the 4 anther-cells forming a broken ring around the apex and 

 dehiscing horizontally, surrounding a minute rudiment of the ovary : 

 female flowers solitary or paired, borne on pedicels 12-28 mm long; 

 perianth-segments 6, similar to those of the male, 3 mm long; glands 6, 

 oblong or oblaneeolate, 1 mm long, almost free but united at the base to 

 a very shallow ring which completely surrounds the ovary ; ovary globose, 

 very obscurely pubescent, 1 mm in diameter, 6-lobed, 3-celled; styles 3, 

 free, forking into 2 slender lobes about 0.5 mm long almost immediately 

 above the ovary: capsule white, depressed-globose, 8 mm in diameter, 

 glabrous, horny in texture, 6-lobed, 3-celled; seeds 4 mm long, outer wall 

 of the testa composed of horizontal fibres, easily ruptured and giving 

 the appearance of brownish pubescence or minute tubercles. 



A shrub 1-3 m high, the branches grayish or brownish, terete, some- 

 what striate, more or less pubescent : leaves borne on pubescent petioles 

 less than 1 mm long, the lamina chartaceous, rhombic-ovate to elliptic, 

 2.5-4 cm long, 1.3-1.8 cm wide, or some of the leaves smaller, equilateral 

 or strongly inequilateral and acute or rounded at the base, the margins 

 slightly recurved and ciliate, the apex mucronate, the upper surface 

 green, glabrous, the under glaucous, pubescent especially on the veins; 

 lateral veins on each side of the midrib 4-6, anastomosing well within 

 the margins; stipules lanceolate or linear-lanceolate, 2 mm long, acumi- 

 nate, pubescent.

This species forms with P. blancoanus, P. stipularis, P. mindorensis and P. 

 leytensis, a very natural group, all showing the same arrangement of stamens 

 and styles, and having a minute rudiment of the ovary at the apex of the column 

 formed by the short united filaments.
