Characteristics

Shrub up to 70 cm, glabrous, innovations covered with numerous, white, elliptic lenticels. Leaves linear, 4-15 by 1-2 mm, submucronate to acute, saccate base c. 1 by 1 mm. Stipules very minute, one at either side of the leaf base. ♂ Flowers terminal or axillary, borne on brachyblasts consisting of a few leaves and one or more flowers, subtended by two sheathed bracts up to 4 by 2 mm, enclosed by a membranous spathella which splits radially and is often crested and saccate at the base, ultimately caducous. Tepals 4, spathulate, membranous, 1.5-2.5 by 0.5-1 mm, obtuse or truncate. Stamens 4, alternate with the tepals, 2-2.5 mm long; filaments linear, winged, in bud with incurved apex; anthers elliptic, c. 1 mm, connective distinctly produced. Ovaries axillary, sessile, obliquely ovoid-ellipsoid, 4-7 by 1½-3 mm, glabrous, the 2 adaxial cells smaller than the abaxial ones. Fruits markedly oblique, up to 11 by 5 by 5 mm, the abaxial cells much larger than the adaxial ones. Ripe seeds not yet known.
More
Monoecious shrub 20–70 cm high. Leaves obovoid, obtusely trigonous in cross-section, 4–15 mm long, 1–1.5 mm wide, rounded acute. Male flowers axillary or terminal, sessile, subtended when young by 2 concave bracts up to 4 mm long and 2 mm wide with membranous margins; the 2 united bracteoles forming a campanulate structure; staminal filaments linear, terete, 2–2.5 mm long; anthers elliptic, c. 1 mm long, the connective distinctly protruding; staminodes 1.5–2.5 mm long, 0.5–1 mm wide. Female flowers solitary (sometimes one fertile male flower between two female flowers at apex of branchlet or with only one axillary female flower and an apical fertile male flower), sessile, obliquely ovoid-ellipsoidal, 4–7 mm long, 1.5–3 mm wide; abaxial locules smaller than adaxial; stigmas sessile, papillate. Fruit an oblique fleshy drupe up to 11 mm long and 5 mm wide. Seeds 5–5.5 mm long, 1.1–1.2 mm wide.
