(Plate LXXVII)

Coarse, soft-woody herbs, at anthesis 6-20 dm tall, at first monopodial, distally branching, becoming shrubby in age, appearing glabrous up to the inflorescence but the purplish-brown tuberculate young stems, the stipules, and leaf-rachises (or some of them) thinly pilosulous with scattered weak spiral hairs up to 0.2-0.6 mm long, the old wood becoming brown and furrowed, the foliage green, the leaflets somewhat bicolored, smooth above, beneath paler, faintly penni-nerved, densely punctate; leaf-spurs 1-1.6 mm long; stipules linear-caudate or linear, (3) 4.5-10 mm long, at least thinly pilosulous distally and ciliolate; intrapetiolular glands spiculiform; post-petiolular glands prominent, mammiform or prickle-shaped; leaves shortly petioled, the main cauline ones 5-11 cm long, with pale, punctate, narrowly thick-margined rachis and 5-9 (10) well-separated pairs of elliptic-oblanceolate or -obovate, abruptly acute or short-acuminate, flat, dorsally keeled leaflets up to 1-1.8 cm long, the margins often minutely gland-crenulate distally, the terminal leaflet stalked, scarcely smaller than the last pair; peduncles 0-1.5 cm long, the first of each major axis often surpassed by several smaller ones terminal to lateral branchlets; spikes racemiform, moderately dense, ovoid-oblong becoming cylindroid, without petals (but including bracts) 14-18 mm diam, the pilosulous axis becoming 2.5-14 (17) mm long; bracts persistent, lance-caudate, 5-10 mm long, the navicular body in profile (0.6) 0.8-1.3 mm wide near base, narrowly pale-margined, green or livid and glabrous dorsally, tapering distally into a livid, ciliolate or glabrate tail nearly as long or longer than the body; pedicels 0.2-0.5 mm long; calyx 5.3-7 mm long, pilose or pilosulous with fine ascending spiral hairs up to 0.6-1.6 mm long, the tube always thinly so and sometimes glabrous, (2.7) 3-4.6 mm long, slightly recessed behind banner, the yellow or castaneous ribs becoming salient, the flat membranous intervals charged with 1 row of large, elliptic, often irregularly confluent blister-glands, the triangular-acuminate, gland- spurred teeth subequal or the dorsal one a little the longest, 2.7-3.4 mm long (0-1.2 mm shorter than tube), the ventral pair shorter and broader; petals greenish-yellow turning sordid or dull brownish-rose, the banner marked with a lobed greenish eye and charged on back of blade with a tuft of hairs, usually (like the keel) gland-tipped but otherwise glandless, the epistemonous ones perched much below middle of androecium (2-3.5 mm above hypanthium); banner (7.5) 8-10.4 mm long, the stout 3- gonous claw 4.5-6.3 mm, the broadly ovate, slightly recurved, shallowly hooded blade 3.2-4.4 mm long, 3.2-4.6 mm wide, callous but open at base and the lobes incurved and adherent to form lateral pockets; wings 5.3-6.9 mm long, the claw 1.6-2.9 mm, the oblong-ovate blade 4-5.3 mm long, 1.7-2.5 mm wide; keel 7.4-8.8 mm long, the claws 2.8-3.8 mm, the elliptic or obovate-elliptic blades 4.5-5.3 mm long, 2.9-3.5 mm wide; androecium 10-merous, 9-11 mm long, the longer filaments free for 2.4-3.2 mm, the connective minutely gland-tipped, the anthers 0.55-0.65 mm long; pod ± 3 mm long, obliquely obovate in profile, hyaline and glabrous in lower 2/3, thence thinly papery, hirsute, gland-sprinkled; seed olive-buff becoming castaneous, ± 2 mm long. — Collections: 10 (o).
