Characteristics

Shrubs up to 0.8 m tall, erect, forming a dense bush single stemmed at base. Branches erect, often dichotomous, slender, with a greyish bark becoming fairly smooth and leafless after about three seasons. Branchlets numerous, erect, slender, somewhat reddened, glabrous, except for some minute puberulence, often in opposite pairs. Leaves 2.8-3.6 mm diam., orbicular, sessile, 4-ranked, opposite, recurved-erect, glabrous, very sparsely and minutely ciliolate; apex with a blunt point; margins narrowly translucent and somewhat denticulate, subcomplicate with a distinct midrib and scattered oil glands; adaxial surface somewhat concave. Florescence terminal, with the white flowers in opposite pairs or fours below which the next years shoots emerge. Bract one to each flower, 2.5 mm long 1.6-2.4 mm broad, ciliolate, leaf-like. Bracteoles two 2.5 mm long, 1.3-1.6 mm broad, elliptic, obtuse, glabrous, keeled, apex thickened; margins minutely ciliolate and translucent below. Calyx lobes five, about 2.5 mm diam., asymmetrically orbicular, glabrous, minutely ciliolate, thickened and spreading at the apex; the margins broadly translucent below. Petals five, 4.5 mm long; limb 1.6-1.8 mm long, 2.2-2.5 mm broad, sub-orbicular, glabrous, pinkish-white; claw 2.5 mm long, 1.5 mm broad narrowing to 0.8 mm below, more or less translucent, transversely bearded above, ciliate, a few hairs down the prominent midrib. Staminodes five, vestigial, a minute gland about 0.1 mm long at most, situated low down on the outside of the disc. Filaments five, at first 0.5 mm long becoming 1.8 mm long after anthesis and placing the discharged anther outside the perimeter of the claws. Anthers five, 1 mm long before anthesis, reddish-orange, with a minute apical gland. Pollen 50-55 µ, long, 28-30 µ broad, oblong. Disc minutely punctate, dark green, closes somewhat over the ovary, exudes nectar. Stigma 0.6 mm diam., globose, capitate. Style becoming 1.2 mm long, glabrous, erect, persisting. Ovary 5-carpellate, each carpel with a gland clasped at the apex and minute spiky lumps along adjacent edges. Fruit 5-carpellate, 5.5 mm long, about 3.8 mm diam., glabrous, smooth; carpels with about 6 gland dots along the margins and a few very short hairs above; horns 1 mm long or less, erect, clasping a small gland at the apex, equalling the persistent stigma. Seed (from Williams 2025) 2.7-3 mm long with the white aril produced a further 0.6 mm, 1.5 mm broad, black, shining.
