Osteospermum moniliferum, Z. 
Visitors Hymenoptera : species of Halic tus ? Diptera : 
small species ab. Coleoptera : Mylabris capensis Tromeces 
linearis. 
Ursinia, sp. 
Visitors : — Coleoptera : Dichilus dentipes , very ab., Ani- 
sonyx ursus , A. longipes , etc. 
Cryptostemma calendulaceum, R. Br. 
The arrangement of the hairs on the style, and its shape, is 
very similar to C. hypochondriacum , Br. described by Hilde- 
brand (Muller, No. 357). The styles rise and fall as in Gazania 
pinnata, Less, (vide infra). Visitors : — Hymenoptera : Blalictns 
de cep tus, H. vittatus , and another. Diptera : Bombylius styli- 
cornis , Lucilia argyrocephala , Systocheilus mix tus, Dischistus 
heteroceras , and another. Coleoptera : Dichilus simplicipes , 
and others. 
Arctotis aspera, Z. 
A. acaidis has been described and figured by Hildebrand 
(Muller, No. 357). This species possesses the same cylindrical 
thickening at the end of the style and this cylinder has a 
basal circle of hairs, besides being covered all over by short 
rigid teeth. The style below the thickened part is highly 
elastic and can be stretched half its length without breaking 
(see Gazania). Visitors : — Coleoptera : Dichilus acanthopus , 
Hedybius , etc. 
Gorteria diffusa, Th. (Fig. 89.) 
The style ends in a thickened part similar to other 
Arctotidae, but there is a peculiar constriction at point c 
below which the hairs are larger (see Fig.). The hairs are 
a bright purple and the pollen-grains yellow through the 
occurrence of oil-globules in their outer coats. 
Gazania pinnata, Less. (Figs. 90 a, 90 b) 
The terminal part of the style is thickened as in Arctotis ; 
the thickening begins with a rim-like projection which bears 
a circle of rather long hairs ; the rest of the thickened part is 
covered with short curved upward-pointing hairs. The style- 
branches are papillose over their whole inner surfaces (cf.
