Flowering from April to October; fruiting from July to next January.
Dactylicapnos lichiangensis is close relative of Dactylicapnos leiosperma, but differs from the latter in seeds echinulate (vs. smooth), sinus between basal pouches to 1 mm deep (vs. basal pouches ca. 2 mm deep).
Dactylicapnos lichiangensis is occurring in SW Sichuan, SE Xizang, C and NW Yunnan of China, India.
Climbers, summer annual. Stems 0.5-2 m long, branched, angular, with a tiny taproot. Petiole 8-18 mm long; leaf blade glaucous abaxially, green adaxially, oblong-ovate in outline, 2-5 cm long (tendril excepted), with 3 alternate often reflexed stalked pinnae; rachis terminating in a long thin branched cirrose tendril; primary leaflets once or twice ternate; ultimate leaflets ovate to lanceolate, 3-30 mm long, 2-13 mm wide, base broadly cuneate, margin entire, apex acute or obtuse, with a small ± curved mucro. Inflorescence 1-3-flowered; peduncle 5-20 mm long (rarely more) in fruiting stage; bracts linear-lanceolate, 2-8 mm long, ca. 0.8 mm wide, irregularly lacerate. Pedicel 5-10 mm long, apically thickened and ± papillose-scabrid along ridges in fruit. Sepals 4-6 mm long, ca. 1 mm wide, with broader deeply dentate base and narrowly oblong to linear apical part. Corolla pale yellow, oblong, 12-16 mm long, 4-4.5 mm wide, slightly broader at base; outer petals slightly saccate at base; sinus between basal pouches (i.e., where pedicel is inserted) to 1 mm; apices of outer petals only slightly diverging, bullate, mucronate; blade of inner petals ca. 1/4 as long as petal, with dorsal crest prolonged beyond apex proper 1-1.5 mm; nectary sigmoidally curved, tapering to a fine short tip. Stigma squarish, 2 apical corners with small stigmatic papillae, basal papillae conspicuous, hornlike reflexed-prolonged. Capsule green, linear-oblong, 3-6 cm long, 2-3 mm wide, not constricted between seeds, with thin flat valves that leave a persistent replum behind upon falling, 10-27-seeded. Seeds black, dull, rounded-reniform in outline, 1.7-2 mm long, densely echinulate, with small rounded elaiosome. Self-compatible.
Growing in forest margins, shrubs, slopes, limestone scree, roadsides; 1700-3300 m.
