the basal portion of the midrib in the under surface ; the midrib 

 conspicuous, straight; veins erect-patent, slightly curved upwards; 

 veinlets finely reticulated. Corymbs terminal on the branches, rather 

 densely branching, peduncles and pedicels glabrous with caducous 

 bractlets. Flowers dense, short-pedicellate, 9mm in diameter. Calyx 

 5-dentate ; teeth minute, erect, carnose, deltoid, acute or rather obtuse, 

 usually entire, ciliated with curly light-rufous hairs, persistent; the 

 calyx-tube glabrous, depressed obconical. Petals 5, patent, imbricated in 

 the bud, white, deciduous, orbicular or oval, 3-5^ mm long, 3-4 mm 

 broad, mostly eroso-crenulate towards the apex, sometimes emarginate, 

 sessile with the rounded base or shortly attenuated towards the base 

 to form a short claw. Stamens 20-18, shortly exserted above the calyx- 

 teeth, incurved at first, but erect afterwards ; filaments subulate with 

 dilated bases, the outer filaments exceed the inner ones; anthers 

 orbicular, auricled at the base. Disk glabrous but villose with curly 

 hairs only around the beses of styles. Styles 5, slender, terete, 

 erect, closed, lower than the longer stamens, slightly curved outwards 

 at the ends; stigmas somewhat thicker, terminal. Ovary inferior, 

 5-celled, with 2 collateral ascending ovules in each cell. Fruits, when 

 young, smooth, subobovate-globose, shortly attenuated at the base, with 

 old styles and filaments in the concave summit provided with con- 

 nivent persistent calyx-teeth, 8 mm in length, 5 mm in diameter in 

 young ones of our specimens, 5-celled ; young seeds elliptical or oblong,
