Content

Description

Tree 3-15 m tall, young stems ferruginous-hirsute-tomentose. Leaves paripinnate or imparipinnate; petiole plus rachis 9-30 cm long, hirsute; petiolules 1-3 mm long, hirsute; leaflets (3) 6-10, alternate or less often opposite, chartaceous, the adaxial surface glabrous, with puberulent midvein, the abaxial surface sparsely hirsute, especially along the prominent venation, oblanceolate, elliptic or oblong, 6-18 × 3.5-6.5 cm, the apex acute, acuminate, or apiculate, the base slightly to strongly asymmetrical, cuneate to obtuse, the margins straight or slightly revolute, serrate, with mucronate teeth. Thyrses 5-20 cm long, paniculate, tomentose; dichasia simple or compound; bracteoles lineate, 2.5-3 mm long. Sepals hirsute, elliptic, 1.2-2 mm long; petals unguiculate, elliptic, 2.5-2.7 mm long, glabrous except for the pubescent claw; appendages of two suprabasal, marginal projections, wooly-pubescent, as long as the petal; disc annular, glabrous; stamens 8, ca. 4 mm long, the filaments wooly at base. Capsules turbinate-trilobed to tricoccate, reddish orange, 3-locular, the cocci short to elongated and divergent, 0.5-1.5 cm long; pericarp ca. 2 mm thick, outer surface ferruginous, hirsute, tomentose-hirsute or sparsely hirsute, inner surface densely creamish wooly, the stipe 3-4 mm long.

Notes

The collection Bosbeheer 3025 from Suriname shows intermediate characters between C. hirsuta and C. rubiginosa, possibly representing a hybrid between both species. Plants have chartaceous, flattened leaflets with non-revolute margins like C. hirsuta, while they are tomentose, have petiolules > 3 mm long, and the capsules are tomentose and scrobiculate like C. rubiginosa.
