Morphology General Habit
Suffrutex or a 2–5-stemmed shrub up to 1.6(2.5) m high; stems erect, straight, 2–3.5 mm thick at the base, terete, simple to few-branched, rarely much branched, shortly hairy, more sparsely so towards the base, with hairs patent, whitish to ferruginous.
Morphology Leaves
Leaves opposite or 3-whorled; lamina 1.7–15.5(20) × 1.2–7.5(6.8) cm, sometimes unequal at the same node, longer than the internodes, elliptic to lanceolate, rarely obovate, acute to acuminate or tapering attenuate at the apex, sometimes nearly caudate, long attenuate-cuneate towards the base, tapering into a subpetiole, entire or usually coarsely and irregularly serrate-dentate to pinnatilobed with 1–7 teeth or lobes on each side, the teeth large, broadly triangular and acute to subobtuse, or small, short and acute in smaller leaves, the largest teeth or segments sometimes 1–2-dentate, the blade membranous, usually slightly discolorous, drying darker mainly above, shortly pubescent with scattered thin hairs above, more densely so beneath mainly on the nerves; petiole usually not distinct from the narrowly attenuate leaf base; short branchlets sometimes present with 1 to few pairs of small, entire or few-dentate leaves.
