Characteristics

Decumbent to prostrate, many-stemmed, suffrutescent, approximately 10-25 cm high. Roots woody and sometimes tuberous. Stems herbaceous to woody, up to 50 cm long, 1-3 mm in diam., with a double indumentum the first of which is pubescent with curved hairs and the second is composed of few to many long erect straight gland-based hairs, sometimes with stalked glands, always with sessile glands Leaves alternate at the base of the main stems, opposite towards their apices and on the lateral branches those of a pair often unequal, the smaller leaves with lateral branches and/or inflorescences in the axil; petiole with the same indumentum as the stem or sometimes with the short indumentum lanuginose, 0.3-0.6 x as long as the blade, 8-20 mm long, flattened at the base; stipules acicular to subulate, with the same indumentum and glands as the stem or velutinous, 5-11 mm long, reddish; blade very narrowly angular-ovate to narrowly angular-ovate, rarely narrowly ovate in the basal leaves, 3.5-6 x as long as wide, mostly folded upwards along the midrib, 20-45 x 5-10 mm, acuminate and mucronate or toothed at the apex; truncate at the base; unevenly serrate at the margin; the teeth with short and long straight erect hairs and furthermore, often thickened by globular pockets of resinous granules; above granulose, obscurely to moderately sericeous and, furthermore, often also with scattered long straight erect gland-based hairs, with sessile glands; beneath lanuginose or velutinous with scattered long straight erect often gland-based hairs on the main veins, densely granulose and pubescent or sericeous in between the veins, with numerous sessile glands; main veins pinnately arranged, impressed above, prominent beneath. Inflorescences axillary and terminal, 1-2-flowered, 50-105 mm long. Peduncles and pedicels slender; the peduncles with the same indumentum and glands as the stem, 15-35 mm long, 0.7-0.8 x as long as the pedicels; the pedicels with a double indumentum the first of which is lanuginose, curved-pubescent or sericeous and the second is composed of long erect gland-based hairs, with numerous stalked and sessile glands, 20-40 mm long and geniculate under the fruit; involucral bracts 2-3 per flower, very narrowly ovate to very narrowly obovate, with the indumentum of the pedicels. Sepals narrowly ovate to ovate, green, free, 2-3.5 x as long as wide, 10-15 x 4 mm; outside with the indumentum and glands of the pedicels and with the long hairs, furthermore, even more dense; inside glabrous, with 3 parallel main veins; margins ciliate; the mucro terete with a globular pocket of resinous granules and a tuft of hairs at its base, 2-3 mm long, greenish, with the same indumentum as the sepals. Petals obtriangular, 2-3.5 x as long as wide, 20-30 x 10-20 mm, 2-3.5 x as long as the sepals, 2-2.5 x as long as the stamens, white or yellow, with venation purplish-brown, with 5 main veins, outside glabrous or rarely obscurely villous, with sessile and subsessile glands, inside obscurely villous, winged, obscurely ciliate and hairy at the base, obscurely crenate or entire at the apex. Stamens monadelphous, arranged in a cup-shaped column around the pistil, groups basally connate for 1.5-2.5 mm; filaments of each group basally connate for 2.5-4 mm; filaments in the central stamens 9-10 mm and in the lateral 7 mm long, apically terete, obscurely hairy inside, more clearly so outside; a narrowly triangular or triangular, rimmed gland is situated on the outer side of the base of each group or on the receptacle outside each group; anthers oblong, equal or subequal, those of the long filaments slightly larger, 2.5-3.5 x 1.3-1.4 mm, subintrorse. Pistil 10-12 mm long; ovary broadly obovoid, 2 x 2 mm, hyalino-hirto-pubescent; beak longitudinally grooved, 5-7 mm long, pubescent, and also with stalked glands in the basal part; stigmas linear to clavate, 2-3 x 0.4-0.6 mm, outside sparsely hairy and blackish, obscurely crenate at the margin, acute or acuminate at the apex.. Fruit with the mericarps 9 x 2 mm and the beak 45 mm long; mencarps narrowly obovoid, hirsute, obliquely domed and reticulate at the apex; the tad hirsute outside, hispid inside where the tails detach from the beak-axis; these stiff hairs somewhat longer at the tail's base, forming a crest. Seed obovoid, 5 x 1.5 mm, glabrous.
