Characteristics

Shrubs 250-300 mm tall, slender, single-stemmed below. Branches few, extremely slender, smooth, erect, leafless, reddish-brown, 1-2 chotomous. Branchlets few, filiform, short, rather sparsely leafy, exoderm like snake skin splitting off, arising from immediately below the inflorescence. Leaves 4-5 mm long, 1 mm broad, lanceolate, scabrido-mucronulate, glabrous, 2-fariously gland-dotted, very sparsely ciliolate or eciliate, adpressed erect, alternate margins broadly translucent. Inflorescence terminal, up to 6-aggregate with flowers about 4 mm diam., pure white, contracted at the throat. Bract 1.7-2.3 mm long, 0.6-0.8 mm broad, lanceolate, acute, mucronulate, gland-dotted, glabrous, sparsely ciliolate, margins translucent. Bracteoles two, 1.1 mm long, 0.4 mm broad, lanceolate, mucronulate, glabrous, sparsely ciliolate, margins translucent. Calyx lobes five, 1.8 mm long, 0.9 mm broad, ovate-lanceolate, mucronulate, glabrous, gland-dotted, ciliolate, margins broadly translucent. Petals five, 3.1 mm long, clawed, bent inwards at the throat; limb 2 mm diam., orbicular, glabrous, spreading, pure white; claw 1.1 mm long, 0.7 mm broad, margins above shaggy ciliate. Staminodes five, 0.05 mm diam., an absolutely minute vestigial scale on the outside of the disc. Filaments five, becoming 0.6 mm long after anthesis, glabrous, erect. Anthers five, 0.5 mm long, 0.3 mm broad before anthesis, reddened with a minutely stipitate apical gland. Pollen 28 µ long, 17 µ broad, oblong with a rather thick skin. Disc closes over the ovary to some extent. Stigma 0.15 mm diam., globose, capitellate. Style becoming 0.6 mm long, glabrous, erect. Ovary 2-carpellate, ±0.3 mm diam.; carpels glabrous, bifid at the apex. Fruit and Seed not seen.
