The Leguniinosas and GraminefB are both better 

 represented than the Composit^e, which, as compared with 

 other parts of South Africa, are relatively scarce. The 

 Leguminosae, Gramineas, Cyperace^e, Acanthacea?, 

 Euphorbiace»,Rubiacea3,Scrophulariaceae,Labiata3, 

 Convolvulace^, Cucurbitaceas, climbing Asclepia- 

 dacea3, Malvaceee, Amarantacea3, Urticacege, Sola- 

 nacese, VerbenacefB, Bixineas, Anonace^e, Cappari- 

 daceee, all show remarkable ti'opical affinities. 



Many families well represented in the midlands of Natal 

 are poorly represented on the coast, e.g. Sterculiaceae, 

 Geraniaceas, Umbellif erae, Campanulaceae, Crassu- 

 laceae, Ericacas. The largest coast belt genera are among 

 Dicotyledons: Indigofera. Ipomasa, Senecio, Rliyn- 

 chosia, Vitis, Vernonia, Euphorbia, Helichrysum, 

 Solanum, Hibiscus, Rhus, Plectranthus, Justicia, 

 Thunbergia, Polygala, Celastrus, Utriculariaj and 

 among Monocotyledons: Panicum, Eragrostis, Andro- 

 pogon, Cyperus, Mariscus, Kyllinga, Digitaria, 

 Eulophia, Habenaria, Asparagus, Commelina, Kni- 

 pliofia, Aloe. 



For the purposes of comparison Bolus' analysis of the 

 chief families with 4764 species belonging to the south- 

 eastern region as a whole is given in Table III.
