Names
Ochna angustata N. Robson [family OCHNACEAE], in Bol. Soc. Brot., Ser. 2, 36: 20 (1962). Type: Mozambique, between Mocubela and Bajone, 7·7 km. from Mocubela, Barbosa & Carvalho in Barbosa 4265 (K, holotype; LMJ).
Information
Shrub or small tree 1–5 m. high, sometimes much branched, with rough whitish bark; branches spreading, purplish-brown and striate at first, soon becoming whitish and terete with few lenticels. Leaves petiolate; lamina 4–9·5 x 1·5–3 cm., elliptic to oblong or rarely lanceolate, rounded or more rarely obtuse at the apex, with margin crenulate-serrulate to subentire, broadly to narrowly cuneate and narrowing towards the petiole at the base, subcoriaceous, with main lateral nerves slightly more prominent than subsidiary ones and the reticulate tertiary venation scarcely visible above and almost plane below; petiole 3–6 mm. long, slender. Flowers 3–4 (5), in umbels terminating short axillary shoots; pedicels 1·3–3 cm. long in fruit, articulated within 3 mm. of the base. Sepals 4–5 mm. long in flower, elliptic, rounded, becoming orange-red, 9–11 mm. long, flat and spreading in fruit. Petals bright yellow, 11–12 × 6–8 mm., obovate or oblong-obovate, shortly unguiculate. Stamens with anthers 1·5–2 mm. long, as long as the filaments, straight, dehiscing by apical pores. Carpels 5 (7), with styles almost completely united; stigmas slightly enlarged. Drupelets 5–6 × 5–6 mm., globose or subglobose. inserted near the base; embryo straight.
Habitat
Deciduous woodland and coastal scrub.
Range
Known only from Mozambique from Beira northwards, in areas within c. 40 km. of the coast.
Altitude range

Distribution
Mozambique MS Cheringoma, between R. Urema and Burundi, fl. 10.ix.1942, Mendonça 179 (LISC).Mozambique Z Maganja da Costa, between Pebane and Mocubela, fr. 25.x.1942, Torre 4675 (LISC).Mozambique N Between Corrane and Muatua, fr. 7.xi.1936, Torre 974 (COI; LISC).
Notes
O. angustata is closely related to two species from W. Madagascar — O. pervilleana Baill. a species with white petals and acute or acuminate leaves, and Diporidium (= Ochna) baronii Van Tiegh. which has 1-flowered inflorescences. O. pseudoprocera Sleumer, from SE. Tanganyika, is also closely allied but differs in having sharply acuminate membranous leaves and larger flowers in 1–3-flowered inflorescences.
