but the phenomenon was not as general in these as amongst the species of 
Rhus. The following list of such plants was made : — 
Montiuia acris (1, f). 
Zantedeschia aethiopica (o). 
Sonchus Ecklonianus (o). 
Cliffortia polygonifolia (o). 
Salvia africana (o). 
Anthospermum ciliare (o). 
Athanasia trifurcata (o). 
Mohria caffrorum (o). 
Leonotis Leonurus (r). 
Bobartia spathacea (r). 
Peucedanum galbanum (r). 
Gymnosporia buxifolia was giving off new shoots, but as the plants were 
confined to the water-courses they had been somewhat protected and the 
aerial shoots had not been killed. A common plant in the water-course 
at the foot of valley B was Clutyia pulchella, and although the old stems 
appeared badly charred, they were giving off new shoots over the whole 
surface. This was an unusual method of regeneration, the only other 
plant behaving in a similar way being a young Eucalyptus tree which was 
growing on the slopes above valley C. 
A week later another visit was paid, and the only change noted was that 
certain plants were now in flower, viz. Curculigo plicata, Oenanthe fili- 
formis, Andropogon hirtus, and Oxalis livida. The two first-mentioned 
species belong to the same class of plant as Haemanthus coccineus, the flowers 
in all cases appearing some considerable time before the leaves. 
In the Cape Peninsula there are two marked periods of flowering activity. 
The first begins about the end of March and attains its maximum with the 
first winter rains. Numerous species of Oxalis are characteristic plants of 
this period. The second and major period is in the spring, towards the end 
of the rainy season. These two flowering periods are well marked on the 
area under discussion, and it is noteworthy that in general there was no 
obvious forestalling of the periods in 1919. However, though the times of 
flowering remained as in normal years, the same cannot be said of the quan- 
tity and quality of the flowers produced. In both these respects the flowers 
on the burnt area were far above the average, and this in a year when 
elsewhere the flowers were not particularly fine. 
During April the following plants came into flower : — 
Oxalis tomentosa (a). On the lower slopes only. 
Oxalis variabilis (a). Slightly later than 0. tomentosa.
