Rhus grandidens [family ANACARDIACEAE]
Common names
Toxicodendron grandidens (Harv.) Kuntze: 154 (1891). R. galpinii Schinz: 638 (1908); Engl.: 208 (1921); Schonl.: 37 (1930); Burtt Davy: 501 (1932). Type: Transvaal, Barberton, Umvoti Creek, 700 m., fl. 10.1889, Galpin 646 (Z, holo.!; BOL!, K!, PRE!, iso.).
Information
Slender to fairly dense shrub from 1,5 to 2 m high with a vegetative and floral morphology similar to R. transvaalensis (no. 4). Bark and young branchlets are, however, always smooth and glabrous and the leaflets narrowly elliptic to oblanceolate and prominently paucidentate to pauciserrate with each tooth mucronate. Petiole (8—)15(—32) mm long; terminal leaflets (18-) 38(-70) x (3-)14(-30) mm, lateral leaflets (13-)25(-51) x (3-)10(-20) mm. Drupe 3,0x 2,4 to 4,2 x 3,8 mm.
Habitat
The width and size of the leaflets and drupes decrease progressively southwards. Acocks 13415 (PRE) from Lusikisiki District has some lateral leaflets 3 mm wide and drupes 3,0 x 2,4 mm. It is also not unusual to find that one of the lateral leaflets has an entire margin while the other leaflets are severely toothed.
Use
5. Rhus grandidens Harv. ex Engl, in A. & C. DC, Monographiae phanerogamarum 4: 440 (1883); Diels: 587 (1898); Engl.: 215 (1921); Schonl.: 41, t. p. 40 (1930). Type: Natal, Gerrard & McKen 1399(K, holo.!; BM!, TCD!, W!, iso.).
