Description:
Usually a very small shrub less than 1m tall, rarely taller in our region. leaves opposite, narrowly to broadly elliptic-oblong, somewhat obovate or lanceolate, up to c. 26 cm long but usually shorter, fairly thinly textured, mostly hairless but sometimes hairy beneath particularly on the midrib. Stipules large, up to 2.2 × 1.5 cm, 2-lobed in the apical half, sometimes ciliate on the margins. Inflorescences on a peduncle 1-9(15) cm long, compact-capitate, surrounded by involucre bracts, 7-9 mm long, distinctly longer than wide. Flowers small, white, c. 6 mm in diameter. Fruit ellipsoid, c. 1 cm long, blue to black, sometimes crowned by the persistent calyx.
Notes: This variety is part of a large complex of taxa needing revision and it not unlikely that it may deserve specific rank. It differs from the other variety in our region, var. nyassana, by the less leathery leaves, which are sometimes hairy beneath and narrower involucral bracts, which are distinctly longer than wide.
Derivation of specific name: peduncularis: pedunculate, referring to the stalked inflorescences;
angustibracteata: with narrow bracts.
Habitat: In the understory of submontane and riverine evergreen forest.
Altitude range: (metres) 690 - 1200 m
Flowering time:
Worldwide distribution: This variety is apparently restricted to various isolated forested mountains in Zimbabwe and Mozambique, such as Chirinda Forest, Mt Gorongosa and Serra de Morrumbala.
