Shrub or shrublet, 0.1-0.2 m tall, bushy, ericoid, with branches strict, lateral, creeping and rooting at the base. Stems 4-lined when young, soon 2-lined, eventually terete, eglandular. Leaves sessile; lamina 2-9 x 0.5-3 mm, narrowly elliptic or lanceolate-elliptic to linear, concolorous, not glaucous, incurved and proximally slightly carinate, imbricate-appressed, rarely distally outcurving; apex rounded, base narrowly cuneate; venation: c. 3 pairs of main lateral veins, curved-parallel, unbranched except near apex and margin, without noticeable tertiary reticulation; laminar glands pale, linear, sometimes interrupted to punctiform near apex and margin, rarely mostly striiform to punctiform; intramarginal glands spaced, pale only or pale and black. Inflorescence 1-flowered, with flowering branches from scattered axils down stem; pedicels 2-4(-8) mm long in fruit. Flowers 10-27 mm in diam., stellate or usually obconic; buds narrowly ovoid-cylindric, subacute to rounded. Sepals 3.5-8 x 1-3 mm, imbricate or not, equal, ovate to lanceolate or elliptic to narrowly oblong, subacute to rounded, entire; veins 7-9, forked and distally branched; laminar glands pale, all or mostly linear or rarely punctate; inframarginal to marginal glands pale only or pale and black. Petals dark to pale yellow, sometimes tinged red dorsally, 7-15 x 3-6 mm, c. 2 x sepals, obovate-oblong to oblanceolate- spathulate, rounded, apiculus absent or almost so; laminar glands pale, linear, sometimes interrupted distally; marginal glands absent or rarely few, black, prominent. Stamens not obviously 3-fascicled, (13)20-30, longest 4-7 (-9) mm, c. 0.5-0.75 x petals; anther gland amber or black. Ovary 2-3 x c. 1 .5 mm, ovoid, acute; styles 3, 1 .5- 2.5 mm long, 0.5-0.65 x ovary, divergent; stigmas narrowly to scarcely capitate; placentae 3, intrusive parietal. Capsule (5.5-)6-9 x 3.5-5 mm, c. 1.3-1.5 x sepals, ovoid, with valves longitudinally vittate. Seeds orange-brown, 0.5-0.8 mm long, carinate; testa densely linear-foveolate. 2n = 24 (Borgmann, 1964, as H. macgregorii).
