Acmadenia burchellii Dümmer

Shrubs about 0.3 m tall. Branches slender, fairly straight; bark dark brown, somewhat roughened with sloping leaf scars. Branchlets fairly numerous, erect, slender, straight, glabrous, leafy, angular when dried with a sharp ridge decurrent from each leaf base. Leaves 6-8 mm long, on younger plants up to 10 mm long, 1.4-1.6 mm broad on one side, complicate when dry, lanceolate, acute, glabrous, sub-sessile, erect, imbricate, opposite, apex with a small mucro hooked inwards; margins ciliolate, broadly translucent; adaxial surface pubescent towards the apex; abaxial surface glabrous, gland dots scattered. Bracts two, opposite, 8 mm long, 3 mm broad, lanceolate-elliptic, acute, sessile; apex with a small callus, sacculate, adaxially pubescent; margins ciliolate, broadly translucent; abaxial surface glabrous, sharply ridged, minutely gland-dotted, rather more remote from the bracteoles than usual. Bracteoles two, 7 mm long, 3 mm broad, elliptic-lanceolate, acute, sessile; apex with a small callus, sacculate, pubescent inside; margins ciliolate, broadly translucent: abaxial surface glabrous, sharply ridged, minutely gland-dotted. Calyx lobes five, 8 mm long, 2.6-3.2 mm broad, elliptic-lanceolate, acute; apex with a small callus, somewhat sacculate, pubescent inside; margins ciliate, broadly translucent; abaxial surface glabrous with many small gland dots. Petals five, 14-5.5 mm long overall, glabrous; limb 8.5 mm long, 4-4.5 mm broad, elliptic, acute with small scattered gland dots, brilliant pink, spreading: claw 7 mm long, 1.5 mm broad above, 0.7 mm broad below, midrib prominent. Staminodes five, 1.3 mm long, 0.33 nun broad below, tapering, apex glandular, glabrous, purplish. Filaments five, becoming 1.8 mm long, acicular, glabrous, purplish. Anthers 1.8 mm long, 0.8 mm broad; apical gland minute, sessile, globose. Pollen 49 µ long, 26 µ broad, oblong. Disc obvallate, narrow, exceeds the ovary and stigma by a long way at first. Stigma 0.6 mm diam., capitate, depressed globose. Style becoming 1.7 mm long, glabrous, rather stout. Ovary 5-carpellate, 0.9 mm long, 0.8 mm diam., glabrous; apices globose, somewhat retuse. Fruit 5-carpellate, 7 mm long, 5.5 mm diam., glabrous, very few gland dots, remaining more or less hidden within the persistent calyx lobes; horns reduced to a mere point, erect, less than 1 mm long. Seed about 4 mm long, black, shining; aril small, white.
