Characteristics

Prostrate or decumbent, several-stemmed, probably perennial, 10-30 cm high. Stems herbaceous to woody, up to 30 cm long, 1-  in diam., viscid, with a double indumentum the first of which is lanuginose or pubescent with curved or straight hairs, most of which are gland-based, and the second is composed of numerous long straight erect gland-based hairs, with stalked and sessile glands. Leaves opposite; those of a pair sometimes subequal; petiole with the same indumentum as the stem, 0.4-0.6 x as long as the blade, 9-15 mm long, sometimes geniculate at the apex, sometimes flattened at the base; stipules subulate to acicular, 7 mm long, reddish, frail, with the same indumentum as the stem but sometimes less dense; blade simple, ovate, broadly ovate or orbicular, 1-1.5 x as long as wide, 15-30 x 10-20 mm; emarginate or obtuse at the apex; cordate at the base; crenate to bluntly serrate at the margin; on both sides velutinous, lanuginose or pilose with gland-based hairs, sometimes also granulose beneath, with numerous sessile glands; main veins subpinnate, impressed above and prominent beneath. Inflorescences axillary, 1-flowered, 30-60 mm long; peduncles and pedicels slender, with the same indumentum as the stem; peduncles 0.2-0.5 x as long as the pedicels, 3-15 mm long; pedicels 15-25 mm long, geniculate under the fruit; involucral bracts 2 per flower, subulate, with the same indumentum as the stem. Sepals green, free, narrowly ovate, 2.7 x as long as wide, 8 x 3 mm, outside sericeous or lanuginose, with sessile glands, inside glabrous or hairy, with 3 parallel main veins, margin ciliate; mucro terete, 2-4 mm long, greenish, sericeous, with a globuliferous pocket of resinous granules at the base. Petals obtriangular, 1.2-1.4 x as long as wide, 15-20 x 14mm, 2-2.5 x as long as the sepals, 2 x as long as the stamens, creamy, venation purplish-grey, with scattered sessile glands, with 5 main veins; outside glabrous; inside obscurely villose; winged, obscurely ciliate and obscurely hairy at the base; sinuate at the apex. Stamens monadelphous, arranged in a cup-shaped column around the pistil; groups basally connate for 1.5 mm; filaments of each group basally connate for 2.5 mm; filaments in the central stamens 8 mm and in the lateral 6 mm long, terete and recurved at the apex, glabrous inside, hairy outside; an ovate, rimmed gland-cavity is situated on the outer side of the base of each group; anthers oblong, all equal, 2.4 x 1 mm, subintrorse. Pistil 7 mm long; obovoid, 2.5 x 1.5 mm, hyalino-pubescent; beak longitudinally grooved, 3 mm long, pubescent in the apical part, tomentose and with stalked glands in the basal; stigmas clavate, blackish and obscurely hairy outside, margin 0 bscurely crenate, apex acute. Fruit 43-45 mm long; mericarps 11 x 2 mm and beak 33 mm long; mericarps narrowly obovoid, hirsute, obliquely domed at the apex, hirsute outside, hispid inside where the tail detaches from the beak-axis; these stiff hairs copper coloured and long at the tail's base, forming a crest. Seed narrowly obovoid, 6 x 2 mm, villose. The one specimen with flowers and fruit was collected in June and the other with only flowers in December.
