Herbs perennial, prostrate, 5-40 cm tall. Stems multibranched, erect, procumbent, or ascending, appressed pubescent. Petiole ca. 1 mm; leaf blade linear or linear-lanceolate, 10-20(-27) × 2.5-3 mm, membranous, 1-veined, both surfaces glabrous or sparsely hairy, base attenuate, margin entire, apex shortly acute. Racemes opposite to leaves or supra-axillary, 1-3 cm, rather few flowered; rachis filiform, 1-3 cm. Pedicel ca. 1.5 mm; basal bracteoles 2, caducous, lanceolate. Flowers 3.5-4.5 mm. Sepals 5, persistent, green, ciliate; outer sepals 3, ovate-lanceolate, ca. 2 mm, apex acuminate; inner sepals 2, obovate to falcate, ca. 3 mm, apex acute, aristate, ciliate. Petals 3, connate at base, yellow; lateral petals broadly obovate, ca. 2 mm; keel cucullate, nearly as long as or slightly shorter than lateral petals, apex with 2 fascicled appendages, each fascicle deeply lobed at apex. Stamens 8, lower 2/3 united, forming an open staminal ciliate sheath and split in upper 1/3 into 8 free filaments; anthers ovoid. Ovary obovoid, ca. 1 mm, winged, ciliate; style curved, apex hooklike; stigma in hook. Capsule obovoid-ellipsoidal, ca. 3 mm, ca. 2.5 mm in diam., narrowly winged, ciliate, apex notched. Seeds black, ovoid, ca. 3 mm, white pubescent; strophiole ± cucullate, 3-lobed, lobes membranous. Fl. and fr. unknown.
Erect to prostrate, usually much-branched herb, sometimes woody at base, up to 40 cm high. Stem terete, set with short, curved hairs. Leaves lanceolate to linear-lanceolate, 5-50 by 1-5 mm, subsessile, mucronate, with recurved margins, shortly hairy, 1-nerved. Racemes usually supra-axillary, the free part 0.5-2 cm long. Bracts usually persistent, minute, ciliate. Flowers (3.5-)4-5 mm long, yellow or dull orange, with green and partly red alae. Sepals lanceolate, acuminate and with a short mucro, cilio-late, alae asymmetric, 5-nerved. Upper petals slightly to distinctly shorter than the keel, spathulate, inside hairy in basal half; keel with 2 bundles of shortly incised appendages. Ovary quadrangular with rounded edges, stiffly hairy in upper part along the margin; style strongly curved in apical part, subapically strongly reflexed with the stigmatic lobe inside. Capsule shorter than the alae, usually asymmetric, usually broadly elliptic, 3.5-4 by 2.5-3.5 mm, notched, narrowly winged, the wings with both short curved hairs as well as with long stiff hairs. Seeds ellipsoid, at micropylar side with an unequally 3-lobed aril, black, hairy.
