Characteristics

Shrubs probably up to 1 m tall, arising from a single stem at base. Branches fairly straight, glabrous, dark brown, smooth with transverse leaf scars becoming double-lipped when old. Branchlets fairly numerous, slender, straight, erect, glabrous, tinged with red. Leaves 26-32 mm long including petiole about 1.5 mm long, 1.2-1.3 mm broad, linear, acute-subulate, glabrous, spreading-erect, alternate; margins narrowly translucent, minutely serrulate with erect sharp points; adaxial surface flat; abaxial surface rounded, multi-gland-dotted to either side of the midrib. Inflorescence solitary, terminal or axillary, sessile, pale pink or white. Bract 4.5 mm long, 0.9 mm broad, linear-lanceolate, subulate; margins ciliolate, broadly translucent below, rolled in above; adaxially very sparsely pubescent along the midrib; abaxially glabrous, gland-dotted, midrib prominent below. Bracteoles two, 3.3-3.4 mm long, 1.1 mm broad, lanceolate, subulate; margins ciliolate, broadly translucent below, rolled in above; adaxially sparsely Pubescent along the midrib; abaxially glabrous, gland-dotted above. Calyx lobes five, 3.5 mm long, 1.4 mm broad, oblong, subulate above with a long sharp Point; margins ciliolate, broadly translucent below, rolled in above; adaxially sparsely pubescent towards the midrib; abaxially glabrous, gland-dotted above. Petals five, 6.3-6.5 mm long overall, 2.7-3.0 mm broad, elliptic, apiculate, glabrous, eglandular, without any translucent margins; claw 2.7 mm long, connate with the staminode with an elevated groove running 0.6 mm up above the apex of the staminode. Staminodes five, 2.3 mm long, connate with the claw of the petal except at the apex which is tipped with a small gland. Filaments five, becoming 2 mm long, erect, glabrous. Anthers five, 0.6 mm long, 0.5 mm broad, yellow; apical gland small, somewhat pointed. Pollen 30 µ long, 21 µ broad, ellipsoid. Disc obvallate, exceeds the ovary, equals the top of the stigma at first, fairly narrow and level on top. Stigma 0.5 mm diam., depressed globose, sessile at first. Style erect, glabrous, becoming 1 mm long, persisting. Ovary 5-carpellate, 0.8 mm long, 0.8 mm diam., glabrous; apices globose with an immersed gland. Fruit 5.0-5.5 mm long, 4.5 mm diam., glabrous, gland-dotted; horns 1 mm long, incurved-erect, with an immersed gland facing outwards at the tip. Seed 3.3 mm long, 1.5 mm broad, black, shining.
