tree-shrub

形態特徵

• Small trees or shrubs, 1.5–2 m tall.
• Leaves oblong to rhombic, 7–10 cm long, 5–6 cm wide, acute, base broadly cuneate, entire, glabrous on both surfaces, or minutely stellate abaxially when young, lateral nerves 7 or 8; petioles 3–10 mm long.
• Inflorescences simple racemes, terminal, 4–6-flowered, glabrous; calyx inconspicuously 5-toothed; corolla tube 3–5 mm long, lobes ovate to ovate-lanceolate 11–14 mm long, 3.5–5 mm broad, densely minute-stellate on both surfaces.
• Fruits ovoid, ca. 1.2–1.4 cm long, base with persistent cup-like calyx.
• In view of the distinct geographical range and the difference in the flower size, Masamune & Suzuki's treatment of the Taiwan and Philippine plants as a separate variety is here adopted.
