Names
Strychnos pungens [family STRYCHNACEAE]
Common names
S. occidentalis Soiered., I.e. (1892). Type not cited; sunk under above by Solereder in second reference.
Information
An evergreen tree 2-7 m tall with thick fissured bark. Branchlets thick, rough and corky, swollen at the nodes, but the ultimate twigs 2-4 mm diam. about midway, with a rather thick waxy splitting skin and persistent slightly prominent suberect leaf-bases. Leaves coriaceous rigid, usually glabrous, with a pungent point, ovate to ovate-oblong or oblong-elliptic, 1 • 5-6 • 5 cm long and 0 ? 7-3 cm broad, narrowing somewhat to the apex where the midrib is excurrent as a pungent, 2-4 mm long spine, rounded or broadly cuneate at the base into a thick 1-4 mm long petiole, nerves 3-5 from the base, the marginal pair sometimes obscure or absent, midrib prominent beneath, the rest slender but prominent on both surfaces. Cymes axillary, clustered, subsessile, simple or compound, about 1 • 5 cm long, each branch 3-flowered; peduncles and pedicels short, pubescent; bracts ovate-oblong, concave, about 1-5 mm long. Calyx 5-lobed (sometimes 4-lobed) to the base, lobes somewhat unequal, imbricate, broadly ovate with a short acuminate apex, ciliate. Corolla greenish, 5-lobed to about midway, glabrous outside with a dense fringe of hairs in a ring at the mouth of the tube; tube about 3 mm long; lobes about 3 mm long, thick with thick margins and an incurved apex. Stamens glabrous, erect; filaments short, triangular, inserted in the mouth of the tube; anthers about 1-75 mm long. Ovary 2-celled with a ring of long hairs where it narrows into the style, ovary plus style about 4 mm long; stigma terminal. Fruit green or bluish-green turning yellow brown, globose, up to 10 cm diam., many seeded, rind thick (3-4 mm thick), woody; seeds up to 2-7 cm diam., embedded in yellowish pulp which has a strong smell, testa becoming hard and not shrinking with the endosperm (as in S. innocua subsp. dysophylla).
Habitat
This species is easily distinguished by its pungent-pointed leaves. The fruit usually has a strong smell and is inferior, from the palatable stand-point, to some of the other species with large fruits. Reports from South West Africa state that in those regions the fruit is palatable and has not got a disagreeable smell. This feature may vary with the locality.
Use
6. Strychnos pungens So/era/, in Pflanzenfam. 4, 2: 40(1892); Bot. Jahrb. 17: 554 (1893); Prain & Cummins in F.C. 4, 1: 1051 (1909); Bruce & Lewis in Kew Bull. 1956: 268 (1956); Bruce & Lewis in F.T.E.A. Loganiaceae: 24 (1960). Syntypes: Angola, Welwitsch 4778 (K); Tanganyika, Fischer 374 (BM).
Range
Grows in dry sites on ledges, rocky slopes, or at the base of stony koppies in the central and western Transvaal and in sandy regions of northern South West Africa. It has also been recorded from Bechuana-land and from central tropical Africa.
