Description: Perennial herbs with distichous leaves, plant form clump, height less than 2 m (about 176 cm tall), has green stilt root, 7-8 plants per clump, 8-9 pairs of leaves per plant.
Leaves alternate, spiral or distichous; petiolate or subsessile, presence of pulvinus; extrafloral nectaries absent or present, convex, sessile or stipitate, located between the pairs of leaflets or on the petiole; leaflets 1-many pairs, papyraceous to coriaceous, elliptic to oblong, lanceolate to obovate, apex acuminate, rounded to mucronate, base oblique.
Leaves 3 to 15 per plant, leaf sheaths reddish, glabrous, conduplicate, equitant and distichous, subcoriaceous to chartaceous, elongate, with about 50 distinct nerves, 5-9 cm long x 0.8-10 cm wide; base of leaf blades gradually passing into the petiole, petioles slender, 1.5-10 cm long, glabrous, narrowled toward the apex; leaf blades subcoriaceous, lanceolate, 5-13 cm long x 1-1.3 cm wide, glabrous on both sides, sparsely verrucose along the veins on the lower surface, with 12-15 secondary veins, the base attenuate, the apex long-acuminate, acumen ca.
In the laboratory, from each quadrate, leaves were removed from 15 shoots in distichous order of insertion and separated into the various categories defined by Giraud [18].
The oldest groups of this subtribe with a distichous phyllotaxy (e.g.
Basal leaves distichous, up 55 cm long, (4-)5-pinnatisect, ovate, thick, divisions often whorled, lobes linear to linear-lanceolate, mucronulate.
The leaves typically are distichous and may be 3-25 cm long and 2-8 mm wide with a basally pilose adaxial surface and a glabrous to pubescent abaxial surface (Freckmann & Lelong 2003).
The leaves may be small to medium sized, simple, alternate, spiral or distichous, broadly elliptic and pubescent.
The leaves are produced in a distichous phyllotaxis, but when the meristem is transformed to a reproductive meristem, its first lateral structures (branches) are produced in a spiral; this shift has been investigated extensively in maize.
