description
Trichoscypha acuminata grows as an evergreen tree up to 18–20 meters high. The trunk diameter reaches about 45 centimeters. The longitudinally cracked, thin and red-brown to greyish bark flakes off in scales.
The alternate, very long and stalked leaves are alternately pinnate, unpaired and crowded at the pointing ends. The leaves are 50 to 150 centimeters long with a petiole. The leaf stalk, which is thickened at the base, is rusty and tomentose and the rachis is more or less hairy and streaky. The approximately 15–35 short-stalked and slightly leathery, almost bald leaflets have entire margins and are ovate, lanceolate to oblong. They are 10-25 inches long and 3-8.5 inches wide and are pointed to tailed at the tip. The runny leaf stalks are up to 1 centimeter long and somewhat hairy.
Trichoscypha acuminata is dioecious dioecious . There are kauliflore , trunk-born and short and soft, rusty hairy panicles on the lower trunk. The male, up to 30 centimeters long and wide inflorescences are somewhat longer than the narrow female ones. The unisexual flowers are arranged in dense "heads". At the base of the panicles there are larger, sloping bracts , the more or less durable, small bracts of the flowers are sub-like. The pink to red, short-stalked and very small flowers are four-fold with a double flower envelope . The small, cup-shaped and short-toothed calyx is dense and finely haired. The 2-3 millimeters long, ovoid and spreading to recessed petals, with a conspicuous central nerve on the inside, are more or less fine-haired on the outside. The male flowers have 4 slightly protruding stamens with sparsely hairy anthers. The female flowers have a rusty, hairy, upper ovary with 3–4 very short styles with slightly bilobed stigmas and small staminodes. There is a sparsely hairy discus , lobed in the male flowers .
There are velvety hairy to almost bare, red to dark purple, about 3-5.5 cm long and ovoid to ellipsoidal, seeded drupes formed.
