Names
Rhus montana [family ANACARDIACEAE]
Common names
R. gerrardii (Harv. ex Engl.) Diels var. montana (Diels) Schonl.: 78, t. p. 78 (1930); Burtt Davy: 507 (1932).
Information
Slender, single to multistemmed deciduous shrub to small spreading tree up to 2,25 m high. Bark smooth, glabrous, grey-brown; young branchlets glabrous, pale brown. Leaves (3-)5(-7)-foliolate, petiolate; petiole terete to canaliculate above, (ll-)24(-34) mm long; leaflets sessile, membraneous, slightly dis-colorous, glabrous, dark green above, pale olive below, turning orange-red in autumn, hypostoma-tous; lamina elliptic to narrowly elliptic or obovate, base cuneate to attenuate, apex acute to acuminate, mucronulate; margins entire or prominently pauciserrate in upper half, teeth mucronulate; venation kladodromous to semi-craspedodromous in toothed leaflets, midrib pale, prominent below, other veins impressed yet still visible below; terminal leaflets (27-)44(-68) x (8-)12(-16) mm, lateral leaflets (19-)30(-42) x (6-)9(-14) mm. Panicles much branched, multiflorous, terminal and axillary, up to 100 mm long. Flowers normal. Drupe circular, obloid, glabrous, shiny, pale brown, 3,5 x 3,0 to 4,0 x 3,5 mm.
Habitat
The 5(-7)-foliolate plants are readily recognizable but as entire, toothed, 3- and 5-foliolate leaves sometimes occur on the same plant, each type usually on its own branch, the determination of isolated herbarium sheets is very difficult. Habit is of the utmost importance and to the trained eye the venation pattern below and the membranous leaflets are diagnostic. Trifoliolate specimens are however easily confused with either R. transvaalensis (no. 4), R. grandidens (no. 5), R. dentata (no. 7) or more rarely R. pyroides var. gracilis (no. 15c).
Use
6. Rhus montana Diels in Engl., Botanische Jahrbucher 40: 86 (1907); Schonl.: 247 (1911); Engl.: 215 (1921). Type: Transkei, near Engcobo, 1350 m, Bolus 8837 (Bf; K, lecto.! vide Fernandes: 131 (1967); BOL!, GRA!, PRE!, isolecto.).
Range
Occurs in scrub forest along the escarpment just north of Wakkerstroom, then in the higher foothills of the Qwa Qwa and Natal Drakensberg reaching as far south as the mounÂtains near Engcobo west of Umtata. Flowering recorded in October and January. Map 6.
