Adult lvs with petiole 1-3 cm long; lamina mostly 10-20 cm long, lanceolate to narrow-lanceolate, coriaceous, somewhat falcate, concolorous, usually ± glaucescent; veins diverging at 30-45° from midrib; base slightly to moderately oblique; apex acuminate. Umbels axillary; fls 7-15; peduncles 5-20 mm long, ± terete; pedicels c. = buds. Buds 3-5 mm long, clavate, glaucous; operculum < hypanthium, hemispheric with acute apex. Stamens white; anthers reniform. Fr. tapering to pedicel, 7-10 × (6)-7-8 mm, pyriform or clavate with truncate apex; valves 4, included; disc narrow, obliquely descending or nearly flat.
