Effects of a Bush Fire on the Vegetation of Signal Hill. 
225 
Towards the end of October a further visit was paid, and most of the 
plants that had been noted in September were found to have finished 
flowering. Other plants had taken their place, the most conspicuous of 
these being Moraea pavonia var. lutea. This plant was abundant on the 
lower slopes of the burnt area, and the tall stems tipped with comparatively 
small yellow flowers provided the dominant note in the vegetation. On a 
more detailed survey of the area it was found that a large number of grasses 
were in flower, and these together with Moraea pavonia may be said 
to characterise the late spring period. The following list of grasses 
was made : — 
Vulpia bromoides (-a). 
Lasiochloa ciliaris (a). 
Aira caryophyllea (o). 
Briza major (a). 
Melica racemosa (f). 
Ehrharta calycina (f). 
Festuca scabra (f). 
Andropogon hirtus (f). 
Bromus molliformis (1, f). 
Briza minor (o). 
Ehrharta erecta (o). 
Lolium rigidum (o). 
Avena barbata (o). 
Brizopyrum capense (o). 
Bromus unioloides (o). 
Hordeum murinum (o). 
Aristida angustata (r). 
These grasses were widely distributed over the lower slopes of the whole 
area. 
In addition to the grasses, the following plants were noted as being in 
flower : — 
Water-course of valley A. 
Lobelia Erinus (f). 
Ranunculus pubescens (f). 
Ranunculus muricatus (f). 
Caucalis africana (f). 
Valley slopes and ridge. 
Moraea pavonia var. lutea (a). 
Trifolium angustifolium (a). 
Rhus lucida (a).
