Characteristics

Shrubs slender, amongst bush and restios. Branches few, somewhat lax, slender, glabrous, smooth, leaf scars not prominent, dichotomously branched. Branchlets few, slender, short, somewhat erect, glabrous, hidden by the leaves. Leaves 5.5-8.5 mm long, 1.4-2.0 mm broad, lanceolate, obtuse, glabrous, opposite, decussate, imbricate, erect, sessile, reddened; abaxial surface smooth with few indistinct gland dots to either side, with the midrib rounder and somewhat translucent; translucent margins ciliate becoming eciliate. Inflorescence terminal; flowers 12 mm diam., white with the pedicel about 2.5 mm long, usually in groups of two opposite pairs. Bract 7.2 mm long, 2.2 mm broad, leaf-like at base of pedicel. Bracteoles two, 5 mm long, 1.5 mm broad, oblong, halfway up the pedicel, glabrous except for a few hairs on the lower part of the midrib; apex purplish, thickened; margins ciliate, broadly translucent, one or two indistinct gland dots towards the inner side. Calyx lobes five, 5.2-5.8 mm long, 2.6-3.0 mm broad, elliptic, obtuse-apiculate, glabrous, reddened above, ciliate, gland dots in two rows above, margins broadly translucent. Petals five, 1.5 mm long overall; limb 5 mm diam., orbicular, apiculate, glabrous, snow-white, spreading; claw 6 mm long, 1.7 mm broad above, 0.7 mm broad at base, glabrous, bulged inwards at the throat where a more or less round coloured patch can be seen. According to Miss Esterhuysen 'Claws of petals olive-green below, purple-red-brown above, bordered with dull off-white, and form a very conspicuous centre'. Staminodes five, 0.6 mm long, glabrous, narrowing above to a globose apical gland 0.2 mm diam. Filaments five, 2 mm long, glabrous, acicular, erect. Anthers five, 1.8 mm long, 0.7 mm broad, somewhat pinkish; apical gland about 0.15 mm diam., globose, very short stipitate. Pollen 62 µ long, 32 µ broad, oblong. Disc obvallate, exceeds the ovary by a long way closing slightly over it, level on top, pale green. Stigma 0.6 mm diam., capitate, disc-shaped. Style short, glabrous, erect. Ovary 5-carpellate, 8 mm diam., glabrous; apices 2-lobed, scabrid. Fruit and seed not seen.
