description

Male inflorescence

fruit

Putranjiva roxburghii grows as an evergreen tree up to 12-15 meters high. The gray-brown to brownish bark is relatively smooth to pale blackish.

The simple and short-stalked, slightly leathery, thin and drooping leaves are alternate. The slightly hairy petiole is up to 6–8 millimeters long. The leaves are finely sawn or notched on the sometimes slightly wavy edge and blunt to pointed or pointed at the tip. They are egg-shaped, lanceolate to elliptical, lanceolate and almost bald and up to 13 inches long and 4.5 inches wide. The veins are pinnate with thin, weak lateral veins. The small stipules soon fall off.

Putranjiva roxburghii is mostly dioecious diocesan . The male flowers appear in small, axillary and dense, short-stalked flower clusters. The female flowers appear axillary individually or up to four. The mostly unisexual, small, stalked flowers have a simple flower envelope , the petals are missing. In the greenish-yellow male, almost sessile flowers, with 4–5 to 2 millimeters long sepals, up to 3–4 short stamens are present in the lower part . In the larger, whitish-greenish, brownish female, longer-stalked flowers, with 4–5 to 2 millimeter long sepals, there is a large, upper and short whitish hairy, two-, three-chambered ovary with two to three short styles with large, broad , bilobed, sickle-shaped, papillary scar branches formed.

Small, yellowish and finely whitish hairy, short spindle-shaped to roundish, 1.5–2.5 centimeters long, single-seeded stone fruits with often stylus scar remnants at the tip are formed. The relatively smooth, slightly textured stone cores are beige.
