Cremastosperma yamayakatense

Cremastosperma yamayakatense is a tree reaching 1.5–8 (up to 20) m in height, with glabrous young twigs and petioles. Its leaves are narrowly elliptic to elliptic, 11–24 (up to 38) cm long and 3.5–8 (up to 13) cm wide, with an olive-grey green upper surface and light brown lower surface, both glabrous. The primary vein is grooved near the base, and secondary veins number 8–10 (up to 14), forming distinct loops. Inflorescences bear single flowers, axillary on both leafy and older leafless branches, with peduncles and pedicels sparsely to glabrously hairy. Bracts are deltate, acute, and mostly shed during fruiting.
