276 Scott-Elliot . — Ornithophilous Flowers 
Protea longiflora, Lam. 
Visited by Promerops caper, near Houwhoek. 
Protea grandiflora, Thun. (Figs. 11, 12.) 
In this form the style elongates very greatly, and before it 
finally bursts the calycine envelope becomes greatly curved. 
When the separation finally takes place, the style straightens 
by its own elasticity, and a cloud of pollen is scattered. The 
stigma in this form is obliquely placed, while the furrows on 
the style are not so evident as in the other forms. 
Visited by Nectarinia. 
Protea cordata, Thun. (Fig. 16.) 
I have not seen this species fertilised. The stigma lies in 
a minute slit at extremity of the style, while the anther-case 
has more the form found in Serruria. 
Protea scolymus, Th. 
Is quite similar to P. mellifera. 
Leucospermum conocarpum, R. Br. (Figs. 17, 18.) 
The flowers are closely packed together on the spherical 
capitulum. The bracts of all the flowers are well developed, 
and their ends are flattened out and modified somewhat like 
the bracts of a fir-cone. Out of the hemispherical surface 
formed by them projects part of the calyx and styles of the 
flowers. The cavities occupied by the bases of the flowers are 
narrow and much choked by a profusion of white hairs 
springing from the bracts. 
The calyx ends in four horny lobes (all equal) closely 
applied over the end of the style. The anthers, opposite 
these lobes, are also attached to it. The end of the style 
is much swollen, but the swelling is pear-shaped (not cylin- 
drical as in Protea), and scarcely grooved at all. At its 
narrow upper extremity are two slight horizontal ridges, be- 
tween which lies the stigmatic slit. The pollen is shed all 
round the upper surface of the swollen style. It cannot fall
