the younger lateral ramuli with a ring of rusty hairs at their insertion. Leaves 

 rather coriaceous, oblong-elliptical or elliptical, acute or acuminate ; base 

 slightly narrowed or cuneate at the petiole, glabrous, shining above, 2£-4 in. 

 long, H-2 in. broad ; petiole 2-3 lines. Flowers in rather broad, dichoto- 

 mous, many-flowered, terminal cymes, 2-3 in. across, on a peduncle of |-1 

 in. ; pedicels £— | in. with the calyx rusty-tomentose. Sepals ecarinate. 

 Stamens about 8 in each phalange. Ovules 6-9 in each cell of the ovary.

Flowers regular, dioecious, polygamous or hermaphrodite. Sepals 2-6, 

 imbricate or in decussate pairs. Petals 2-6, rarely more, usually much im- 

 bricated or contorted. Male fl. : Stamens usually indefinite, hypogynous ; 

 filaments free or variously connate, monadelphous or in as many phalanges 

 as petals ; anthers various. Female fl. : Staminodia various. Ovary 1-2- 

 Go-celled ; ovules 1, 2, or indefinite, axile or erect from the base of the ca- 

 vity, rarely parietal {Allanblackid) ; stigmas as many as cells of the ovary 

 or variously consolidated, sometimes peltate, entire, sessile, subsessile or with 

 more or less elongate style. Fruit usually baccate, indehiscent with a fleshy 

 or pulpy pericarp. Seeds large, exalbuminous ; embryo of a large radicle 

 {tigella) with small or obsolete cotyledons or of thick conferruminate or free 

 cotyledons and very short inferior radicle. — Trees or shrubs abounding in a 

 yellow or greenish juice. Leaves opposite, coriaceous or submembranous, 

 rarely verticillate, usually exstipulate. Flowers axillary or terminal, solitary 

 fascicled subracemose or panicled, white yellow or red.

 lobes alternate with the phalanges, deeply tuberculate-corrugate on the upp er
