small, in fascicles in the axils of the leaves or of the scars of fallen 
leaves, sub-sessile or shortly pedicelled. Calyx of 5-6 imbricate, 
usually orbicular and obtuse segments. Corolla campanulate, or 
tubular-campanulate, with 5 or rarely 6 lobes, the lobes imbricate. 
Stamens as many as the corolla-lobes and opposite to them, attached 
to the tube or at its base ; filaments linear, usually short ; anthers ovate 
or lanceolate ; staminodes alternating with the stamens, lanceolate. 
Ovary usually villous, with 5 or fewer cells ; style cylindric ; stigma 
small ; ovules erect, placentas axile. Fruit an ovoid or globose fleshy 
berry, 5- or less-seeded, usually with one seed only. Seeds compressed, 
generally solitary ; testa hard, crustaceous, usually shining ; hilutn 
oblong or linear ; embryo erect, cotyledons flat or thickened, in fleshy 
albumen ; radicle short, inferior. — Disteib. About 60 species, mostly 
of tropical regions in both hemispheres, a few only extratropical in 
South Africa or Australasia.

1. Sideroxylon malaccense, Clarke in Hook. f. FI. Br. Ind. III. 
537 (1882). A large tree, reaching 40 to 60 feet in height ; branches pale 
brown ; ultimate branchlets ferruginous-pubescent, as are the leaf-buds 
and young leaves. Leaves coriaceous ; often, not always, crowded 
towards the ends of the branchlets ; obovate-oblong, rounded or shortly 
acute at apex, somewhat cuneate at base ; deep-green above, pale 
bluish-green beneath, yellow when dry, densely rusty-pubescent beneath 
when young, glabrous on both surfaces when old except for rusty hairs 
on the midrib and main-nerves beneath ; 6 to 8 in. long, 3 to 4 - 5 in. 
broad ; midrib very thick and prominent ; main-nerves 8-14 pairs, very 
prominent, starting at about an angle of 60° with the midrib, parallel at 
first, ultimately arched upwards ; reticulations not prominent, obliquely 
joining the main-nerves ; petiole 1 to 1*5 in. long, thick, enlarged at 
base, bordered above by the slightly decurrent margins of the blade. 
Flowers fasciculate, shortly pedicelled, in the axils of the leaves, above
