THE PLANT ECOLOGY OF THE COAST BELT OF NATAL. 437 



shrub or small tree (o.) ; Cluytia spp., undershrubs (a.); 

 Claoxylon sp., small tree (r.) ; Aclenocline sp., herb in 

 fairly dense shade (a.); Macaranga capensis, tree (l.d.) ; 

 in moist places, Dalechampia capensis (515), climber 

 (a.), around outer margin; Spirostachys africana, tree 

 (l.a.) ; Sapium mannianum, tree (a.); Tragia durban- 

 ensis, climber (o.); T. schlechteri, climber (o.); Gelonium 

 africanum, shrub (r.). This is one of the most important 

 families in coast scrub, including a number of connnon trees, 

 one (Macaranga) often dominant. The trees, however, 

 belong more properly to true forest. 



Urticace.e. — Celtis kraussiana (2(S), tree (a.) ; Trema 

 bracteolata (356), tree (l.d.) ; Clifetachme aristata, slirub 

 or small tree (a.) ; Ficus capensis, tree (l.d.); F. natalen- 

 sis, ti*ee (l.d.) ; F. sycomorus, tree (1.<1.), on alluvial mud- 

 flats at river mouths; F. nekbudu (l.a.). The tigs belong 

 to the early forest stages of the hydrosere. Urera ten ax, 

 shrub (l.a.); Ponzolzia parasitica, shrub (o.) ; Australina 

 acuminata, annual herb (f.), and Urtica urens, Fleurya 

 grossa, F. capensis, herbs Avith stinging hairs frequent 

 around the margin. Another important family, but the large 

 trees belong rather to high forest.
