Inflorescence subterminal, the racemes usually ternate, simple, mostly erect or ascending axillary in the 2 or 3 upper nodes of the branchlets, 13-28 cm long, 1-2 cm wide, loosely many-flowered; peduncles slender or stout, 4-7.5 cm long, minutely puberulent or glabrate; rachis glabrous to minutely hirsute or puberulous; pedicels slender, 0.5-1.5 mm long, puberulent or minutely hirtellous; bracts and bractlets absent;
