384 GEOGRAPHICAL BOTANY. 



Acidanthera (Iridaceae) ; and Clinostylis (Liliaceae). Fre- 

 senius has written notices of some Abyssinian plants 

 (Bot. Zeitung, 1844, pp. 353-7). Fenzl has announced 

 a work upon Kotschy's collections from Africa, and in it 

 has enumerated a series of new forms, but without giving 

 any descriptions (Ratisbon Flora, 1844, pp. 309-12). 



A valuable notice of the plants collected by Krauss in 

 the most southern regions of the Cape Colony, and in 

 Natal, with a report on his travels, and a botanico- 

 geographical introduction, has been published by the 

 author (Ratisbon Flora, 1844, p. 46). He accurately 

 describes the large elevated forests, which, are limited 

 to a small area, considering the extent of the whole 

 colony, and extend along the south coast between Gauritz 

 and the Kromme river and the foot of the Onteniqua 

 mountains. According to his account, Drege's represen- 

 tation, contained in E. Meyer's work, of the generally 

 poor character of the forests of the Cape, is not perfectly 

 correct. At least in this district there exists a quantity 

 of timber collected into woods, which Krauss characterises 

 as impenetrable thickets. He mentions some gigantic 

 stems of Podocarpus, which four men cannot span ; more- 

 over Crocoxylon excelsum (Safranhout), Ocotea bullata 

 (Stinkhout), Curtisea faginea (Hassagaihout), and Elce- 

 dendron Capense trees., the large, densely leafy crowns 

 of which are elevated far above the thicket beneath, and 

 covered with numerous climbing plants. Underwood, 

 e. g. Burchellia, Gardenia, CantJiium, Plectronia, Tecoma, 

 Grcwia, Sparmannia, and Rubus. Lianes : Cissus, Cle- 

 matis, Cynoctonum, and Secamone ; Ferns in the deeply- 

 shaded parts. After a tedious ascent, and laborious 

 struggle through the chaos of bushes, is finally reached a 

 thin wood, the trees become smaller and smaller, and 

 their limit is soon attained. They are succeeded by 

 shrubs of Synantheraceae, Thymeleaceae, Bruniaceae, 

 Proteaceae, and Ericaceae. 



Krauss confirms the statement that the river Camtos 

 constitutes a distinct limit of vegetation. This stream
