Description
Species Description - Tree or shrub, 2-9 m tall. Leafy twigs densely covered with weak, white to pale brown, crisped, erect, simple hairs to 0.5 mm long, becoming glabrous. Petioles 3-5(-10) mm long, 0.5-1 mm in diam. Lamina ovate to elliptic, 4-7(-10) cm long, 1.5-3(-5) cm wide, chartaceous, dark greenish-brown above, green to brown below, rather densely to densely covered with weak, white, crisped, simple hairs to 0.2 mm long above, rather densely covered with weak, white, erect to semiappressed, crisped, simple hairs to 0.3 mm long below, base obtuse to slightly cordate, apex obtuse to slightly emarginate; secondary veins curved to straight, (5-)6-8 on either side of primary vein, rarely with short intersecondaries, angles with primary vein 40-60°, occasionally loop-forming down to more than 1/2 of the length, smallest distance between loops and margin mostly 1-3 mm, tertiary veins 2-3 per intercosta, weakly percurrent to reticulate. Domatia scarce, indistinct. Inflorescences leaf-opposed (to supra-axillary), 1 (-rarely 3)-flowered, (peduncles), pedicels, outer side of bracts and sepals, and (most of) corolla densely to rather densely covered with appressed to erect, brownish (to whitish), crisped to straight, simple hairs to 0.3(-0.5) mm long. Peduncles 0-0.5 mm long, 0.7-1 mm in diam., fruiting peduncles to 1 mm long, to 1.5(-2) mm in diam. Pedicels 10-20 mm long, 0.5-1 mm in diam., fruiting pedicels 1-2 mm in diam. Bracts broadly (ovate-)triangular, 1-2 mm long, upper bract inserted in up to 1/3 (or halfway) of the pedicel. Flowers red, fragrant in vivo. Sepals slightly connate at the base, patent, broadly ovate, 1-3 mm long, 3-5 mm wide, shortly acuminate, not gibbous. Corolla tube 3-4 mm high, 3-4 mm in diam., wings suborbicular to obovate, ascending, 7-12 mm long, 6-9 mm high, less than 0.5 mm thick, index = 1-1.3. Fruit subglobose in outline, 2-4 cm in overall diam., apocarpous, green, maturing yellow, orange, or red in vivo, black to dark brown when dry, carpels 15-20, obovoid, 8-13(-l 4) mm long, 4-6(-8) mm in diam., gradually narrowed into a stipe 12 mm long, sparsely covered with white, crisped, simple hairs (to ca. 1 mm long), with obtuse apex, surface slightly to distinctly verrucose; wall ca. 0.2 mm thick. Seeds 8-9 × 4-6 mm, pale brown, pitted.

Discussion
The closest relative of this species is Rollinia parviflora, from which it differs at first glance by the different indument (R. parviflora is covered with ferruginous hairs) and differently colored flowers (white to yellow in R. parviflora, red in the the present species). R. leptopetala is unique in the genus by the red flowers.
