Names
Anthospermum ammannioides S. Moore [family RUBIACEAE], in Journ. Linn. Soc., Bot. 40: 102 (1911). (“ammanioides”).—Puff in Pl. Syst. Evol., Suppl. 3: 209 (1986). Type: Zimbabwe, “Gazaland”, Chimanimani, Swynnerton 2156 (BM, holotype; K).
Information
Dioecious or ± dioecious (male or female plants occasionally with odd hermaphrodite flowers) shrub, single-stemmed, erect, 1 -3 m. tall. Stems much-branched above, branches ascending to ± erect, densely covered with greyish-white hairs 0.2–0.7 mm. long. Leaves in whorls of 3; blades 18–45(65) x (2)3–10(15) mm. (in male often somewhat smaller than in female), narrowly (ob)-lanceolate to oblong-lanceolate, both surfaces sparsely to ± densely covered with very short whitish spreading hairs, but lower surfaces often more densely hairy, particularly on mid-vein, and upper surfaces sometimes ± glabrous; margins usually ± flat; petioles subobsolete or 2–6 mm. long on largest leaves; stipular sheath hairy, with a hairy seta (0.7) 1.5–4(6.5) mm. long, sometimes flanked by a smaller seta on either side. Flowers subsessile (female) or with pedicels c. 0.7–1.5(2) mm. long (male), in clusters of many (very many:female) at nodes, inflorescences dimorphic, in female compact, ± cylindrical inflorescence zones 20–45(70) mm. long and 15–20 mm. in diam.; corolla 4-merous (very rarely 5-merous), greenish-yellow, sometimes buds purplish tinged, at least in male hairy outside. Male (odd hermaphrodite): tube (0.5)0.7–1 mm. long, (± narrowly) funnel-shaped, lobes 1.5–2.4 x 0.6–1 mm.; anthers 1.2–1.7 mm. long; male: minute, hardly discernible rudimentary ovary. Female: tube 0.3–0.5(0.8) mm. long, lobes 0.2–0.5 x 0.1–0.2 mm.; style (0.5)2–5(6.5) mm. long, stigmas (4.8)6–14 mm. long (much shorter in odd hermaphrodite); ovary 0.7–1 x 0.6–0.8 mm., with 4 indistinct calyx lobes or calyx lobes ± lacking. Fruit reddish-brown; mericarps (1.5)1.8–2.2(2.4) x 0.8–1 mm., ± oblong to obovate, glabrous, with 2 indistinct, ± triangular calyx lobes 0.1–0.2 mm. long or calyx lobes ± lacking.
