Vicia longidentata Z. D. Xia.
Herbs annual, (30-)60-80 cm tall. Stem puberulent, rarely villous. Leaves paripinnate, (5-)10-15 cm; stipules semitriangular or triangular-hastate, 2-4(-10) × 6-10 mm, margin 3- or 4-toothed; leaflets (5-)7-11-paired, narrowly oblong to elliptic or obovate, (14-)16-25 × (4-)5-7 mm, membranous, abaxially hairy, rarely both surfaces villous, margin sometimes thickened, apex obtuse or truncate, mucronate; lateral veins dense, obvious; tendril branched. Raceme subequaling (rarely obviously longer than) leaf, (6-)10-14 cm, (8-)10-14-flowered. Calyx campanulate or obliquely so, unequally toothed. Corolla purple or light purple; standard oblong, 11-12 × 4-6 mm, subequaling wings and longer than keel. Ovary fusiform or nearly so; ovules 4(-6). Legume linear, 40-42 × 8-9 mm, glabrous. Seeds 3 or 4. Fl. Apr-Sep, fr. Jul-Sep.
Forests, bush woods, among shrubs, hill slopes, grasslands, roadsides; 2300-3600 m. Sichuan, Xizang, Yunnan [N India (Himachal Pradesh, Uttar Pradesh), Kashmir, Nepal, Pakistan].
Plants in Sichuan with stem shorter (30-70 cm), villous, leaves smaller (5-8 cm), leaflets fewer (5-9 paired), narrowly oblong to elliptic, slightly smaller (1.4-1.8 × 0.4-0.6 cm), villous on both surfaces, and raceme shorter (6-10 cm, longer than leaf) have been called Vicia longidentata (misspelled as "V. longicuspis" in FRPS 42(2): 233, 239, 240, 455. 1998). These characters overlap considerably with those of V. bakeri, with which it seems best, therefore, to unite V. longidentata.
