A plant of the Urticaceae family, the whole-leaved fire hemp tree.
Morphological Characteristics
The whole-leaved fire hemp tree, also known as the whole-leaved fire hemp or the whole-margined fire hemp tree. An evergreen shrub or small tree, 3–7 meters tall; branches spreading, stout, slightly fleshy toward the upper part, gray-green, sparsely covered with prickly hairs.Leaves are leathery or stiff papery, with variable shapes: elliptic, elliptic-lanceolate, oblong, or obovate-lanceolate, rarely rhombic, 10–45 cm long and 5–20 cm wide, with an apex acute to long acuminate; the base is cuneate, rounded, truncate, or deeply cordate; the margin is entire, undulate, undulate-rounded-toothed, or irregularly shallowly toothed;nearly glabrous on both surfaces or sparsely covered with spiny hairs along the veins on the underside; lenticels fine and punctate, particularly prominent on the upper surface; with pinnate venation; 8–15 pairs of lateral veins, the lowest 1–2 pairs arising nearly straight and extending to the margin, while the pairs above are arcuate and interlaced near the margin; veins distinctly raised on the underside;Petiole 2–10 cm long, sparsely covered with soft hairs and bristles; stipules nearly leathery, ovate-lanceolate, 1.5–2.5 cm long, brown, with fine hairs on the outer surface.Inflorescences are dioecious, panicle-like, with relatively short branches; the rachis and branches are covered with spiny hairs, which are denser on the corymbs; male inflorescences are 5–10 cm long; female inflorescences are 10–20 cm long, with corymbs lacking an enlarged fleshy receptacle. Male flowers are nearly sessile, 1.2 mm long when in bud;The perianth consists of 4 segments, sparsely covered with fine hairs and small spines on the outer surface; there are 4 stamens; the rudimentary pistil is obovate, approximately 0.5 mm long. Female flowers are pedicellate; the perianth consists of 4 segments, fused to the middle, of unequal size—the 2 lateral segments are triangular-ovate, nearly 1 mm long, while the 2 dorsal and ventral segments are narrowly ovate and slightly shorter, with fine punctate stalactites and sparse small spines on the outer surface;The stigma is filiform, erect, and 2–3 mm long. The achene is long-stalked, pale green when fresh and turning purplish-black when dry; it is pear-shaped and flattened, 5–6 mm long, with a slightly oblique apex that abruptly narrows into a short beak-like tip; the persistent stigma is curved and bears wart-like projections on both surfaces. Flowering occurs from fall through the following spring; fruiting occurs in fall and winter.
