Characteristics

Suffrutex, bushy, much branched from base; branches and branchlets suberect or ascending, stellate-pubescent or pubescent with short, patent, gland-tipped hairs, sometimes with stellate hairs intermixed, rarely with a few simple patent hairs as well. Stipules from under 1 mm to 4 mm long, up to 1.5 mm broad, subulate to deltoid-oblong. Leaves petiolate, blade elliptic, oblong or obovate-oblong, acute or more often broad at the apex and 3-toothed, up to 27 x 14 mm, upper leaves sometimes narrowly elliptic, entire and acute, 6-20 mm long, 3-4 mm broad, stellate-pubescent on both surfaces, more densely so on the lower, sometimes some gland-tipped hairs present and very minute scales; margins usually crenate-dentate at least in upper portion, upper leaves often entire; petiole 1.2-10 mm long. Inflorescence axillary, 1-flowered; peduncle stellate-pubescent or with usually gland-tipped, patent hairs, about 6-22 mm long, 2-3-bracteate at apex, sometimes with a fourth lower down on peduncle; bracts 1-2 mm long; pedicels 3-7 mm long, pubescent like the peduncles. Calyx lobed to beyond the middle, stellate-pubescent without, often intermingled with gland-tipped hairs, especially on margins of lobes; tube about 2 mm long; lobes deltoid-acuminate, about 5.5 mm long. Petals pink or off-white with a pair of oblong, deep pink patches on lower half of inner face, oblong-cuneate, about 6 mm long, lobed about midway, lobes ciliate and some pubescent on inner face of petal, lower half with inrolled margins. Stamens with hyaline, obovate-elliptic filaments, about 4 mm long, ciliate on the shoulders; anthers acute, about 5 mm long, ciliate, overlapping the filament for 1.5 mm. Ovary stipitate, stellate-pubescent, stipe 1-2 mm long; styles about 6 mm long. Capsules densely stellate-pubescent, about 6 mm long, 5 mm diam., truncate at apex with 5 pairs of horns about 1.5-2 mm long) at apex of sutures.
