A semi-succulent bushy herb 1–2 m. tall, glabrous on the vegetative parts.. Leaf-blades elliptic-lanceolate or narrowly elliptic, (5–)7–18 cm. long, (1.5–)2.5–6 cm. wide, pointed and with a recurved mucro, cuneate, decurrent and unequal-sided at the base, very narrowly translucent at the margin; crystals visible as short raised lines and dots on the younger leaves; primary lateral nerves 6–10 on either side; petiole 1–3 cm. long.. Racemes shortly pedunculate, 6–15(–23) cm. long, subdensely many-flowered, thinly crisped pubescent on the rhachis; bracts subulate or linear-caudate, 1–3 mm. long; pedicels 1–2 mm. long, with narrow bracteoles from the lower part.. Flowers hermaphrodite, whitish or yellowish-green, the sepals sometimes flushed reddish in fruit.. Sepals ovate-elliptic, rounded or bluntly pointed, 2.5–3(–3.5) mm. long, spreading, membranous, glabrous.. Stamens 8–9, a little shorter than the sepals.. Carpels (7–)8(–10), united, glabrous.. Berry depressed-globose, only slightly lobed, with the style-bases around a median depression, 5–7 mm. across, ripening black or purplish-black.. Seeds lenticular, 2–2.5 mm. across, smooth, glossy black.
