Species Description - Tree or shrub 4-16 m high; hairs silky, greyish-white to light reddish-brown, up to ca. 0.4 mm long, appressed or spreading; young twigs reddish-brown, densely to sparsely strigose to velutinous. Leaves mainly elliptic, less often oblanceolate, lanceolate, or ovate, 4-22 cm long, 1.7-9 cm wide, 1.8-3.2 times as long as wide, glabrous to moderately covered with appressed or erect hairs on the blades, usually sparsely to densely covered with hairs on the veins; apex acuminate; base acute to rounded; petiole 3-10 mm long, 1-2 mm thick, shallowly or deeply channeled, moderately strigose to densely velutinous; midvein impressed above, prominent below; lateral veins impressed or flat above, prominent below, 5-9 pairs ascending, the venation brochidodromous to eucamptodromous; blades submembranous to subcoriaceous, drying dark reddish-brown, somewhat darker above than below. Peduncles uniflorous or triflorous, 3-15 mm long, 1-2 mm wide, densely strigose to densely velutinous; bracteoles normally caducous before anthesis, linear (rarely foliaceous), ca. 3-10 mm long, densely covered with hairs; Calyx-lobes triangular-ovate to triangular, 4-9 mm long, 4-6 mm wide, 0.8-1.5 times as long as wide, sometimes auriculate, densely velutinous to moderately pubescent; petals suborbicular, ca. 10 mm long, densely pubescent centrally without, usually glabrous within; hypanthium obconic to campanulate, 7-10 mm long, densely sericeous-velutinous; disk ca. 8 mm across, puberulent; stamens ca. 250-400, ca. 4-7 mm long, erect in the bud; anthers ca. 2 mm long, the connective thickened, drawn out into an apiculum often as long as the anther-locules; style ca. 10 mm long, glabrous; ovary 7-10-locular; ovules ca. 7-10 per locule.

Discussion
Campomanesia laurifolia is easily distinguished from others species when in flower by its apiculate anthers. After anthesis it is distinguished by the sericeous-velutinous hypanthium, and rather large flowers, sometimes borne in 3-flowered dichasia.
