Characteristics

Shrublet, prostrate or creeping, forming mats, 10(-20) cm long. Branchlets elongate, ramose, rooting at the nodes, terete, densely ± longish brownish setulose, reddish when fresh. Leaves alternate (subdistichous), ovate, sometimes oblong, ovate or nearly rounded, apex obtusely acuminate, base rounded or subcordate, ± coriaceous, dark green above, much paler beneath, glabrous above, ± laxly setulose beneath, serrulate, each tooth ending in a longish fine subpersistent bristle, sometimes subentire, margin slightly recurved, (4-) 13 by (3-)5-9 mm, midrib a little impressed above, prominent beneath, nerves 2 (-4) pairs from and somewhat from above the base, inarched and high ascendent towards the edge, subinconspicuous above, raised beneath, transverse veins visible beneath only; petiole setulose, 1-2.5 mm. Flowers solitary in most, but not all upper axils. Pedicels 1-2 mm, provided with 6-7 small triangular-ovate acute ciliolate bracts and bracteoles at and somewhat above the base. Calyx c. 3 mm, deeply 5-partite, whitish green to reddish, lobes ± triangular, acute. Corolla ovoid-urceolate, white or pink, 5-7 by 2.5-5 mm, widest in the lower third, shortly 5-lobed. Filaments linear, slightly hairy, 2 mm; anther-cells oblong, the very short tubules shortly biaristate. Ovary glabrous; style c. 2.5 mm. Fruit blue-blackish or blackish purplish when ripe, succulent, 8-9 mm ø, ± completely including the depressed-globose capsule, which is c. 5 mm ø. Seeds subglobose, apiculate, very small.

Leaves dense; petiole ca. 1 mm; leaf blade broadly ovate or suborbicular, sometimes ovate or elliptic, 5–10(–18) × 3–9(–16) mm, papery or leathery, abaxially densely or sparsely setiferous, usually pale, sometimes red punctate, adaxially glabrous, secondary veins 2 or 3 pairs, secondary and fine veins slightly raised abaxially, inconspicuous adaxially, base obtuse, truncate, rounded, or subcordate, rarely cuneate, margin denticulate-setulose, apex acute, distinctly mucronate. Flowers solitary, axillary. Pedicel ca. 1 mm; bracts ovate-triangular, ca. 1.5 mm; bracteoles 2–4, persistent, stramineous, larger than bracts, carinate, ca. 3 mm, glabrous. Calyx glabrous; lobes ovate, ca. 3 mm, apex shortly acuminate. Corolla white, pink, or crimson, campanulate, ca. 5 mm, abaxially glabrous; lobes often erect, ca. 1 mm, triangular. Filaments spindle-shaped, ca. 1.5 mm, villous, papillate; anthers ca. 1.5 mm, thecae 2-awned. Ovary glabrous. Calyx at fruiting blue-purple or black; capsule globose, 6–7(–9) mm in diam., glabrous. Fl. Jul–Oct, fr. Mar–Dec. 2n = 44.
A shrub which lies along the ground. It develops into a hummock with its twigs woven together. It grows 5-40 cm long. The leaves have short stalks. They are alternate. They are 0.8-2 cm long by 0.5-2 cm wide. They are oval and with fine hairs underneath. The flowers occur singly. They are in the axils of leaves. Flowers are reddish or white.

Environment

In the upper mountain zone, terrestrial on open sunny, rocky places and volcanic debris, on steep crater slopes, not rarely covering the rocks, rarely in ravines within the upper limit of the forest or in ericoid shrub vegetation, occasionally epiphytically there in the moss at the base of the trees, 1300-3500 m, mostly above 2000 m. Rather frequent in Java. Said to be a pioneer plant, holding the loose soil together. Fl. fr. Jan.-Dec.
