Morphology General Habit

A small shrub 1.2–4.5 m. tall, often with swollen pithy floating stems similar to A. elaphroxylon but without spines.

Morphology Stem

Stems densely hispid with golden-brown tubercular-based glandular hairs.

Morphology Leaves

Leaves 16–32(–40)-foliolate; leaflets oblong, 1–3.5 cm. long, 0.4–1.2 cm. wide, rounded and mucronulate at the apex, obliquely rounded at the base, ciliate on margins and main nerve beneath, ciliate-serrulate towards the apex, otherwise glabrous; petiole and rhachis together 7–14(–22) cm. long; petiolules 1 mm. long; stipules ovate or elliptic, 8–10 mm. long, 3.2–5 mm. wide, acute, not appendaged, densely ciliate, soon falling.
