 Mem. viii. b^, partly. A shrub 3-7 ft. high ; branches slightly sulc'ate, 

 with a broad line of short crisped hairs up each side when young, at 

 length nearly glabrous. Leaves elliptic, oblong-elliptic or oblanceolate, 

 obtusely pointed, obtuse or subcuneate at the base, 1^-4 in. long, J-li 

 in. broad, thinly chartaceous or membranous, glabrous on both surfaces 

 often glaucous below, margins recurved ; lateral nerves 9-10 on each 

 side, looped some distance from the margin, prominent below ; petiole 

 1-1 J lin. long, somewhat fleshy, glabrous; stipules subulate or filiform 

 from a broader and auriculate base, brown, membranous, 1-2 lin. long, 

 margins fimbriate or laciniate. Flowers dioecious, axillary, males 

 several in each fascicle with numerous membranous laciniate bracts at 

 the base, females few or subsolitary. Male flowers : pedicel about

 1 lin. broad, not membranous, glabrous on both surfaces. Disk-glands 4, 

 rounded or subreniform, fleshy, very minutely pitted. Stamens 2 ; fila- 

 ments united into a very slender column ; anther-cells quite separated, 

 very small. Female flowers: Sepals 5-6, very broadly ovate, IJ lin. 

 broad, coriaceous, glabrous. Disk saucer-shaped, fleshy, undulately 

 lobed, glabrous. Ovary much depressed-globose, slightly trilobed, 

 glabrous ; styles spreading stellately over the top of the ovary, bilobed, 

 lobes terete and not at all swollen at the tips. Capsule trilobed, 3 lin. 

 in diam. Seeds 3-sided, convex on the back, 1 lin. long, \ lin. broad,
