AN (ECOI.OGIOAL SURVEY OF THE MIDLANDS OF NATAL. 519 



Lianes are very numerous, including: 



Vitis capensis, V. cuneata, V. cirrhosa, Scutia 

 couimersonii, Senecio spp., Dalbergia obovata, 

 Popowia caffra, Cnestis nataJeusis, Strophanthus 

 capensis, Acacia pennata, Ceratiosicyos ecklonii, 

 Jasminum spp., Ipomoea sp., Helinus ovata. Aspa- 

 ragus plumosus. Gassy tha capensis (parasitic). 



Epiphytes are : 



Polystachya spp. (orchids), Angrajcuni spp. (orchids), 

 Mystacidium spp. (orchids), Psilotuna triquetrum, 

 Peperomia caffra, P. sp., Rhipsalis cassytha, Ficus 

 natal en sis, Lye op odium saururus, L. verticil la turn, 

 L. gnidioides, Hymenophy Hum spp., Tricho manes 

 spp.. Poly podium incanum, P. lanceolatum, As- 

 plenium rut^e folium, Gymno gramme lanceolata, 

 Mosses and Hepatics. 



Bush of this composition clothes the southern slopes of the 

 Zwaartkop mountain. The large Karkloof forest, which was 

 estimated by the Forest Commission of 1880 to cover an area 

 of 80,000 acres, lies outside the district mapped.^ 



To the south of the Zwaai^tkop bush, at Ihdeta, there is bush 

 which, though quite similar oecologically, differs slightly in its 

 composition from the type described. It consists of the 

 following ;■ 



Calodendron capense (dominant), Celtis kraussiana 

 (dominant), Xy males monospora (dominant), Kiggelaria 

 dregeana,Toddalealanceolata, Cyclostemonai'gutus, 

 Xanthoxylon capense, Ptasroxylon utile, Ocotea 

 bullata (on high ground), Olea laurifolia (on high 

 ground), Trimeria alnifolia, Podocarpus thunbergii 

 (scarce, but probably more abundant formerly), P. latifolia 

 (scarce), Rhamnus prinoides (around margin), Celastrus 

 buxifolius (around margin). 



It will be seen, therefore, that this bush, not being so much 

 interfered with, contains more of the valuable timber trees.
