Characteristics

Shrubs to 1 m tall, dense, rounded with many stems arising from a single rootstock, apparently able to coppice. Branches numerous, erect, glabrous, stout, tough, more or less clustered; bark dark brown, rough with circumferential leaf scars. Branchlets numerous, erect, slender, thinly deflexed, villous, green, clustered. Leaves 5-9 mm long (including the petiole 1-1.3 mm long), 1-1.3 mm broad, narrowly lanceolate, somewhat obtuse with a blunt callus at the apex, glabrous, recurved-erect, alternate; margins narrowly translucent, at first villous-ciliate becoming eciliate; abaxial surface rounded, gland-dotted to either side of the mid-rib and along both margins. Inflorescence solitary, terminal or axillary, subtended by two or three reduced leaves, one bract and two bracteoles; flower 7.5 mm diam. with petals white, soon delapsing. Bract 2 mm long, 0.6 mm broad, linear-lanceolate, narrowed above; apex with a red callus; margins densely crisped ciliate; adaxially densely crisped pubescent; abaxially glabrous and gland-dotted above, somewhat pubescent below. Bracteoles two, 1.5 mm long, 0.6 mm broad, lanceolate, obtuse; apex with a blunt callus; margins crisped ciliate, translucent below; adaxially somewhat pubescent; abaxially rounded, gland-dotted above, pubescent below. Calyx lobes five, 1.7 mm long, 1.1 mm broad, elliptic, glabrous, ciliate, translucent, apex minutely callused, gland-dotted on the midrib above. Petals five, 3.6-5 mm long overall, 1.9-2.9 mm broad, orbicular with the apex truncate or emarginate, white, glabrous, faintly veined, gland-dotted to either side of the midrib; claw about 2 mm long narrowing to the base. Staminodes five, 1-1.3 mm long, 0.3-0.4 mm broad, fusiform, narrowed below, apex gland tipped, glabrous. Filaments five, becoming 1 mm long, somewhat fusiform, glabrous. Anthers five, 0.7-1 mm long, 0.6 mm broad, yellow; apical gland globose, incurved, minutely stipitate. Pollen 38-40 µ long, 18-20 µ broad, ellipsoid. Disc obvallate, slender, exceeded by the ovary, hidden from above by the swollen filaments and staminodes. Stigma 0.2 mm diam., capitellate. Style glabrous, slender, deflexed at first, becoming erect, 1 mm long. Ovary 5-carpellate, 0.7 mm diam., glabrous, lumpy with oil glands. Fruit 5-carpellate, 5 mm long, 5 mm diam., glabrous, gland-dotted, green, purplish above, deeply divided, hornless, apices emarginate. Seed 3.5-4.1 mm long, 1.7 mm broad, black, shining; aril black.
