Lecomte (1930: 965, fig. 110).

Description

Medium-sized tree ( Lecomte 1930). Young twigs densely hairy, hairs straight or slightly curved, 0.5– 1.5 mm long. Leaves elliptic to elliptic-ovate, 8–13 × 3–7 cm, base cuneate, apex acuminate to caudate, blade glabrous or sparsely hairy on upper surface, lower surface sparsely hairy, more densely hairy on the midrib and lateral veins on both sides of the leaf, hairs same as on twigs but generally straighter; lateral veins 7–9 on each side, arched near the margin, tertiary veins coarsely scalariform and reticulate; petiole (0.4–) 0.8–1 cm long, hairy. Female flowers axillary, solitary; pedicel ca 3 mm long, hairy. Calyx spreading, ca 2 cm in diam., hairy on both sides; lobes 4–5, divided nearly to the base, ovate or elliptic, 1–1.5 cm long, apex acuminate to caudate. Corolla urceolate (flask-shaped), hairy outside along the midveins; lobes 4–5, shallowly divided near the tip, broadly ovate, 1–2 mm long, apex acuminate. Ovary ovoid, densely hairy. Staminodes absent. Male flowers, fruits and seeds not seen.

Distribution

CAMBODIA • Kampot, Phnum Tamie [Pierre 5029 ( A, K, L, NY, P, VNM)]. This species is endemic to Cambodia and only known from the type collection ( Fig. 2 ). A gathering included in Lecomte’s original material of D. tamiriensis from Laos [Massie s.n. (P[P00721748])] belongs to D. strigosa Hemsl .

Notes

Diospyros tamiriensis is resurrected here from synonymy of D. apiculata ( Phengklai 1978, 1981; Pham-Hoang 1991, 1999; Nguyen 1996; POWO 2022).
