 (PI. XXII, figs. 1 and 2). 

 A type of one of the larger vleis. Very wet in some 

 places, drier in others. Stream flows through it, and spreads 

 out over parts of it. 



In giving the above list I have endeavoured to restrict 

 myself to fairly general types. By taking the smaller 

 vleis one after the other it would be possible to extend 

 the list very considerably. Instead of that I shall deal 

 with the other marsh plants under a separate heading, 

 although many of them in the smaller marshes become 

 dominant. 



(14) ASSOCIATED PLANTS OF THE VLEIS. 



In addition to Cy per us latifolius there are many other 

 species of Cyperus. Cyperus fastigiatus, C. sexan- 

 gularis, C. immensus are common. Altogether twenty- 

 four species of Cyperus are recorded for Natal, mostly 

 marsh plants. The other genera of Cyperacese are 

 Carex, Kyllinga, Pycreus, Juncellus, Mariscus, 

 Eleocharis, Finibristylis, Bulbostylis, Scirpus, 

 Ficinia, Fuierena, Lipocarpha, Ascolepis, Rhy- 

 cospora, Costularia^ Cladium, Scleria, Schoenoxi- 

 phium, species of which are found scattered through the 

 marshes, but I have not attempted to work out many of 

 the species of this difficult group. 



Of other common marsh plants the following prefer to be 

 near running water: Eriocaulon spp., Xyris spp., 

 Commelina gerrardi and other species, Cunnera per-
