tnincata, Panicum Marlothii, Themeda triandra, Eragrostis 

 demidata, AnthepJiora pubescens, Fingerlnithia africana, Panicum 

 Hohibii, Eragrostis superba, Aristida congesta, A. brevifolia, A. 

 Burkei, A. uniplumis, A. stipiformis, A. niolUssima, Pogonarthia 

 falcata, Tragus koelerioides, and Chrysopogon serridafus. 



Other characteristic plants occurring in this region are the 

 Wilde Kalabas (Hibiscus urens), the Wild Senna [Cassia obovata), 

 the Cape Slangkop (Ornithoglossum glaucuiii), the Slangkop 

 (Urginea Burkei), the Dubbeltjedoorn (Tribvlus terrestris and T. 

 zcyheri), the Stijfziekte Bos (CrotaJaria Burkeana), the Gousblom 

 (Gazania uni flora), the Pakkiesblom [Herinannia brachypetala), 

 the Duiveitjea (Pretrea zanguebarica), the Kriedoon (Lycium 

 tetrandrutn), and the Vomeerbossie (Geigeria passerinoides). 



Tulps are extremely plentiful and often give the veld a blue 

 or yellow hue due to Moraea polystachya and Homeria pallida. 



The chief succulents are Aloe grandldentata and Aloe 

 Schlecteri var. Orpcniae. 



The pasture and hay grasses of the Griqualand West Thorn 

 Veld are practically the same as those found on the Kaap plateau. 

 One of the most important poisonous plants is Ornithoglossum 

 glaucutn, the Cape Slangkop. Lebeckia psiloloba is suspected of 

 poisonous properties, and Tribulus terrestris, under certain 

 conditions, produces Geel dik-kop in sheep. 



In the tliorn veld of the Harts River Valley, Acacia Giraffac 

 is plentiful and the pods of this tree provide an excellent stock 

 food. 



10. — The Kaap Plateau Bushveld (Plates XII, XIII). 



The Kaap Plateau Bushveld occupies the wide limestone 

 plain which stretches froan a little south of Griquatown to the 

 north of Vryburg. On the east it is bounded by the escarpment 

 of the Campbell Rand, which overlooks the valleys of the Vaal 

 and the Harts Rivers, and on the west by the Asbestos and 

 Kuruman Hills. 



The whole area is remarkably flat, and is characterised by the 

 presence of numerous pans, whose floors are composed of 

 tufaceous limestone. The surface of the ground is hard and 

 uneven and consists very largely of dolomite outcrop. Here and 

 there, however, soil of a sandy nature occurs. 



The plateau throughout is covered by bush or scrub which 

 ranges in height from 6 to 15 ft. This bush is composed mainly 

 of the Olijvehout (Olea verrucosa), the Zuurkaree (Rhus 

 tridactxjla) , the Haakdoorn (Acacia detinens) and the Vaalbos 

 (Tarchonanthus camphoratus). The Haakdoorn is dominant in 

 the south, the Olijvehout and Zuurkaree in the central portion, 

 and the Vaalbos in the north. 



Karroo bush, composed of L'Jiiy.socoina tcnuifoUa and Pentzia 

 incana, is mainly associated with the Haakdoorn, the Olijvehout 

 and the Zuurkaree on tlie shallow dolomite outcrops, while grass 

 veld is more commonly associated with the Vaalbos where the 

 Boil is sandy and deeper.
