Names
Rhus refracta [family ANACARDIACEAE]
Common names
Toxicodendron refractum (Eckl. & Zeyh.) Kuntze: 154 (1891).
Information
Much-branched squarrose shrub up to 3 m high or small crooked stemmed trees up to 4 m high, usually armed. Bark rough, irregularly fissured; branchlets striate, glabrous, puberulous or pubesÂcent, often ending in stout spurs. Leaves trifolioÂlate, petiolate; petiole semiterete, shallowly canaliculate above, glabrous or sparingly pubesÂcent, (4-)8(-12) mm long; leaflets sessile, memÂbranous to submembranous, concolorous, dark green above, slightly paler below, hypostomatous, glabrous, villous to velutinous; lamina obovate, somewhat rugose, base cuneate, apex retuse, rounded to obtuse; margin entire, revolute to slightly revolute; venation kladodromous, midrib and laterals impressed above, midrib and seconÂdaries slightly prominent below, other veins obÂscure; terminal leaflets (8—)18(—32) x (5-)8(-12) mm, lateral leaflets (6-)13(-26) x (4-)7(-14) mm. Panicles puberulous to shortly pubescent, axillary and terminal, latter up to 50 mm long. Flowers normal, corolla lobes narrow, oblong. Drupe circular to oblate, obloid, pruinose, blueish brown, 3,6 x 3,0 to 5,0 x 4,3 mm; stone with pronounced bony lateral process.
Habitat
A coastal, rugose, revolute and hairy leaved morph as well as a glabrous, less revolute morph from inland may be recognized. Without fruit, the inland morph cannot, however, easily be separated from R. pentheri (no. 34).
Use
35. Rhus refracta Eckl. & Zeyh., Enumeratio plantarum africae australis 2: 145 (1836); Walp.: 552 (1842); Sond.: 510 (1860); Engl.: 427, 538 (1883); Diels: 581 (1898); Schonl.: 243 (1911); Schonl.: 45, t. p. 45 (1930); R. & A. Fernandes: 609 (1966). Type: Eastern Cape Province, Uitenhage, Zwartkops River, Ecklon & Zeyher 1103 (S, lecto.! here designated; C!, L!, M!, P!, SAM!, W!, isolecto.).
Range
Widespread in the eastern Cape between the Sundays and Kei River from the coast to near Cradock inland. Its range is extended north-eastwards by a few collections in Transkei and south-westwards by isolated collections near Willowmore and Plettenberg Bay in the southern Cape. There is also a single record from Mozambique. Flowering recorded in January. Map 30.
