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.
Under suitable conditions and without use of pruning, the plants can reach 12-20 m in height, with stem diameter from 40 to 60 cm, and petiolate leaves, alternate and pinnate, with 2-4 pairs of leaflets arranged alternately or opposite in the rachis, with size ranging from 2 to 10.
These leaves with different shapes can be grouped into two distinct categories; the first one is called ovate and includes basal and petiolate leaves, arranged in the form of a rosette, while the second one, the lanceolate, refers to smaller leaves and amplexicaul leaves that emerge after stem elongation.
Imbu were classified as simple (leaf blade is not divided), incomplete (with no sheath), petiolate (brevipetiolate)-with petioles length greater than 15 mm (on average 51,24mm)--and alternately arranged.
The leaves tend to be decussate on the lower stem (with opposite pairs, the succeeding pairs turned 180[degrees]), usually alternate near the stem apex, petiolate, palmately compound (except for small unifoliolate leaves at branch apices), with an odd number (3-13) of coarsely serrate, lanceolate leaflets.
Larger leaf sessile or shortly petiolate, petioles 0.
in having the abdominal base somewhat to strongly petiolate, the first fore tarsomere elongate, the scutum elevated postsuturally, and three spermathecae (one very small, two large) with elongated basal ducts characteristically studded with numerous prominent outgrowths.
Leaves opposite, anisophyllous in a pair, pa pyraceous; larger leaf petiolate, petioles 3-3.
The plant has compound leaves, made up of leaflets which are arranged along with 2 to 6 opposite or sub-opposite pairs of petiolate and subsessileleaflets.
