obtu?C' : nerves '> on each side of the midrib, pi-ominont, sharply ascend- 

 ing, sliglitly curved, obscurely anastomosing, usually brown when dry in 

 contrast to the pale lower surface of the leaf, the reticulations fine, 

 distinct: petioles 5 to 10 mm long, often slightly pubescent. Flowers 

 small, 5-merous, the pistillate ones solitary, axillarv, on 3 to 4 mm long 

 pedicels; sepals free. iml)ricate, ovate, 2 to 4.5 mm long, tlie inner two 

 much larger than the outer ones, pubescent; petals suborbicular, 3 mm 

 in diameter, membranaceous, lounded, ciliate; ovary ovoid, 2 mm in 

 diameter, densely pubescent, 1-celled with three parietal placentae, the 

 ovules numerous; stigmas 3, spreading, flattened, 2 mm long. Staminate 

 flowers small, in very short paniculate racemes, the inflorescence slightly 

 pubescent, axillary, solitary, about as long as the petioles; sepals 5, 

 free, ovate, acute or acuminate, the two inner ones lai'ger than the outer, 

 about 3 mm long in bud, outside ferruginous-pubescent; petals 5, ovate 

 or rounded, membranaceous, ciliate. each witli a large orbicular, ciliate 

 scale at the base, about 1 mm in diameter; rudimentary ovary none; 

 stamens 5; filaments stout, tapering upwards, 1 mm long, glabrous; 

 anthers 1 mm long, about O.fi jnm long, the connective rather broad. 

 Fruit pyriform, indehiscent, the pericarp crustaceous, rather brittle when 

 dry, densely brown- or ferruginous-pubescent, when mature about (J 

 cm long, the base much narj'owed ; seeds about 8 in each fruit, ellipsoid 

 to narrowly ovoid, often irregularly compressed, 1.5 to 2 cm long.

Tliis species is closely allied to H. venenata Gaertn. of Ceylon, but differs in 

 its less niunerously nerved and entire leaves, and in its fruit being strongly 

 narrowed at the base, and pyriform in shape. 



Although the Cejdon flora is not especially closely allied to that of the Philip- 

 pines, and although the Flacourtiaceae is not strongly represented in either region, 

 this family contains a striking series of species peculiar to the two, including 

 the above wliich is manifestly closely allied to Ht/dnocarpus venenata Gaertn., a 

 species confined to Ceylon; the genus Osmelia with but four known species, two 

 closely allied ones confined to the Pliilippines, one in Celebes, and one in Ceylon; 

 and tlie genus Trichadenia, previously a monotypic one and confined to Ceylon, 

 hill of which a second species has now been found in T>uzon.
