Usually an erect bushy shrub very variable in size and habit, reaching 2 metres under protection but frequently reduced to 25 cm in exposed situations. Branchlets more or less densely strigose, with or without a fine white pubescence. Leaves alternate, 8-15 × 6-12 mm, petiolate, orbicular, ovate, or elliptical, membraneous or thick, margins generally serrate, glabrous except for a fine pubescence along the upper surface of the midrib. Flowers solitary and axillary, very rarely crowded towards the tips of branch lets forming a leafy raceme. Pedicels up to 6 mm long or more, strigose and/or pubescent. Corolla seldom pubescent within. Fruit red, pink, or white, berry-like, 4-6 mm in diameter.
Usually an erect shrub up to 1 metre high. Branchlets with a fine pubescence, but bristles completely absent. Leaves alternate, 8-14 × 5-10 mm petiolate, orbicular or orbicular-oblong, extremely thick, apex obtuse, margins bluntly serrulate or crenulate, teeth armed with bristles in the younger leaves, both surfaces completely glabrous, or a few bristles on the upper surface of the midrib, veins very conspicuous on the lower surface. Inflorescence a solitary terminal raceme, rarely one or two lateral racemes also present. Peduncle pubescent. Corolla pubescent within.
An erect or scrambling shrub up to 1.5 metres high. Branchlets more or less strigose, with or without a sparse pubescence. Leaves alternate, 10-20 × 6-12 mm, petiolate, oblong-elliptical, elliptical, or elliptical-orbicular, extremely thick, apex acute but not mucronate, margins bluntly serrulate or crenulate, teeth armed with bristles in the growing leaf, but bristles deciduous, making teeth appear rounded, upper surface with or without a sparse pubescence along the midrib, lower surface completely glabrous, veins very conspicuous. Inflorescence of axillary racemes, sometimes crowded together at the ends of branches. Peduncle and pedicels sparsely pubescent. Corolla pubescent within.
A small depressed or prostrate shrub. Branchlets up to 20 cm long with usually only the terminal 5 cm leafy, strigose. Leaves alternate, often bronze-coloured, 6-10 × 3-8 rom thick, margins crenulate or bluntly serrulate, both surfaces glabrous, veins conspicuous. Flowers solitary and axillary. Pedicels usually very short, about 1 mm long, strigose, but usually completely concealed by the bracts. Corolla usually pubescent within. Fruit red, pink, or white, 8-12 mm in diameter.
Branchlets usually trailing, strigose but not pubescent. Leaves orbicular or sub-orbicular, apex obtuse, teeth armed with long, persistent bristles up to 2 mm long. Pedicels strigose only.
Branchlets often forming dense matted patches, more or less strigose and often with a sparse very short pubescence. Leaves 6-9 × 3-6 mm (sometimes smaller in exposed plants), obovate to elliptic, apex usually acute, margins bluntly serrate, teeth sometimes armed with bristles when very young, but bristles deciduous leaving short spikes, veins very conspicuous, usually impressed. Pedicels usually both strigose and pubescent.
Ramuli strigosi saepe sparse brevissime pubescentes. Folia obovata ellipticave, apice acutiusculo marginibus obtuse serratis, dentes setis deciduis armati, venis conspicuis. Pedicelli strigosi pubescentesque.
A large shrub, 1 to 3 metres high. Branchlets without pubescence or setae. Leaves opposite, 25-60 × 15-30 mm, length seldom more than twice the width, sessile or almost so, cordate, ovate or ovate-oblong, very thick and coriaceous, mucronate at the obtuse apex, margins slightly thickened, bluntly serrulate, teeth mammilate, upper surface with or without a fine pubescence along the midrib together with a few bristles (or their bases in older leaves), otherwise glabrous and glossy, lower surface densely strigose, especially on the veins of young leaves, only the hair bases remaining on older leaves. Inflorescence of axillary and terminal racemes, the latter often compound forming broad terminal panicles with opposite spreading branches. Peduncle and pedicels glabrous. Corolla glabrous within.
A large shrub, 1 to 3 metres high. Branchlets pubescent and usually densely strigose, especially near growing tips. Leaves alternate, 20--40 × 6-12 mm, length usually three to four times the width, petiolate, oblong-lanceolate, elliptic-Ianceolate, or oblanceolate, thick but not excessively so, mucronate at the acute apex, very acute at the base, margins more or less thickened, bluntly serrulate, teeth armed with bristles in the growing leaf, but bristles deciduous leaving short spikes, upper surface with pubescence and a row of bristles. along the midrib, lower surface sparsely or densely strigose, veins conspicuous. Inflorescence of axillary and terminal racemes, often crowded at the .tips of branches.. Peduncle and pedicels pubescent. Corolla more or less pubescent within.
Leaves usually less than 30 mm long, elliptic-Ianceolate, often fairly sharply serrate. Corolla glabrous.
A small creeping densely matted much-branched shrub, with erect leafy branchlets up to 5 cm long, but mostly less than 3 cm, densely and very minutely puberulous. Leaves alternate, 3-7 × 2-4 mm, shortly petiolate, elliptic or elliptic oblong, extremely thick and coriaceous, almost entire or with 3-4 obscure teeth on either side, glabrous and shining, veins conspicuous. Flowers large and solitary, terminal or both terminal and axillary. Pedicels less than 1 mm long, minutely puberulous, with 2-4 bracts at the base. Bracts broadly ovate, up to 1.5 mm long. Margins of calyx lobes entire and membraneous, inner surface minutely puberulous. Corolla sparingly pubescent within. Stamens as long as the style, filaments 2 mm or more long, ribbon-like, 0.1 mm wide, gradually expanding towards the base, not papillose. Anthers 0.5-0.6 mm long, opening by minute terminal flaps and clefts down the sides, apparently awnless.
Fruticulus depressus, vage ramosus, ramulis prostratis, radicantibus, ramulis ascendentibus dense puberulis. Folia alterna breviter petiolata, elliptica elliptici-oblongave, crassa coriaceaque, glabra, vix serrata. Flores solitarii, plerumque terminales, brevissime pedicellati, calycis lobis integris marginibus membranaceis. Stamina stylum aequantes, filamentis laevibus basim latissimis, antherae inaristatae.
A small shrub of matted growth, main stems slender, prostrate and rooting, with ascending tips up to 5 cm long, but usually about 2 cm long. Branchlets glabrous or with a short dense pubescence. Leaves rather distant, alternate, 2-4 × 0.5-1.5 mm, shortly petiolate, elliptic or linear-elliptic, usually thick but not excessively so, margins with up to three microscopic dentations on either side, glabrous or with a dense pubescence on the upper surface, veins prominent. Flowers large, axillary and terminal. Pedicels up to 3 mm long, glabrous or nearly so, usually with two small basal bracts and two larger upper ones. Bracts ovate, margins ciliate. Margins of calyx ciliate, inner surface pubescent. Corolla glabrous within. Stamens as long as the style and nearly exserted. Filaments ribbon-like, 0.1 mm wide, gradually widening to 0.3 mm at the base, not papillose. Anthers 0.4-0.6 mm long with distinct blunt awns about 0.1 mm long. Fruit a pink globose berry 4--5 mm in diameter, seated in the persistent unchanged calyx.
