than the petiole. Leaves oblong to oblong-lanceolate, attenuated acuminate 

 with an emarginate tip, rounded-obtuse at base, faintly crenate, coriaceo- 

 chartaceous, glabrous, deep green above, light green beneath, minutely 

 pellucid-punctate, 3i-9 cm. long, l|-4^- cm. broad ; midrib prominent on 

 both surfaces ; veins about 5-11 on each side, patulous, curved and connecting 

 above ; veinlets inconspicuous superficially in living specimens but j)romi- 

 nently reticulated beneath when dried ; petiole winged, cuneately oUanceolate 

 to obovate, shortly terete at the base, glabrous, 1-4 cm. long, 4-22 mm. 

 wide. Flower axillary, or rarely terminal, pedicellate, usually solitary or 

 sometimes geminate, about 18 mm. across, odoriferous ; the pedicel about 

 4-18 mm. long, narrow, with laxly placed caducous subulate ciliated scale- 

 bracts. Calyx about 8 mm. across, patent, green, persistent, 5-cleft ; lobes 

 depressed-deltoid, or deltoid, somewhat unequal in size and some of them 

 subulato- deltoid or more or less linear-foliaceous above, a little produced 

 and obtuse, thick, glabrous, more or less concave within, minutely ciliated. 

 Corolla erect-patent, pure white, deciduous ; petals 5, narrowly oblong- 

 spa thulate, obtuse, entire, thickish, sparsely ])unctate externally, about 

 14-15 mm. long, 5^-7 mm. broad. Stamens erect, shorter than the 

 corolla, 16-21-antheriferous ; filaments united into 5 bundles or sometimes 

 sub-tubular with short and free tips, 1 to 5-antheriferous to a bundle, the 

 bundle rectangular-spa thulate, but linear-filiform in that of one-antherifer- 

 ous one ; anther elliptical or oblong-elliptical, introrse, shortly apiculate at 

 top, bifid at base, yellow. Disk annular, entire, glabrous. Ovary somewhat 

 depressed-globose, truncate at top, glabrous, thick-carpeled, 9-11-celled, 

 many-ovuled, about 3^ mm. across ; style erect, lower than stamens, thick, 

 cylindrical ; stigma globose ; ovules minute, horizontal, in 2 rows. Fruit 

 globose, somewhat depressed, 4^-8 cm. across, yellow, often scarcely mam- 

 millated at top and concave in its centre, depressed at base, ammatic, the 

 surface more or less uneven, the oil-glknds sparse and slightly concave; the 

 rind thick, white and spongy interiorly, closed to cells, 9-11-celled, with 

 thin dissepiments ; cells packed with a soft tissue of indistinct fusiform and 

 yellowish vesicles, filled with an acid juice, the axis white and spongy ; 

 pedicel terete. Seeds usually many, oblong-obovoid, often a little com- 

 pressed, smooth, pale-yellowish, about 13-17 mm. long, the rhaphe more or 

 less distinct ; testa firm ; tegmen membranaceous, slightly thicker and rose-
