346 Scott Elliot . — On the Fertilisation of South 
depression along their upper surfaces, into which the alar 
depression fits. The style and stamens emerge by a rather 
oblique slit at the end of the carina. 
Aspalathus sareantha, Vog. (Fig. 55.) 
The basal lobe of the vexillum on each side fits into a 
deep superior hollow of the ala, which again works on a 
lateral projection of the carina. The lower edges of the alar 
claw (just before the limb) are turned inwards, and touch one 
another below the carina. On depression the alae rotate on this 
horizontal portion, which is just inside the calyx. The stigma 
and anthers emerge as in A. aemula. The alae have a marked 
tendency to curl upwards, so that when set free from the 
carina their tips come in contact with the vexillum ; this 
tendency will assist in bringing back the carina to its original 
position after depression. 
Aspalathus Chenopoda, Thnnb . (Figs. 51-54.) 
This form shows a further advance in structure, as the 
claws both of alae and carina are firmly adherent to the sta - 
minal tube , and bending is entirely confined to the junction of 
alar limb and claw. The inner edges of the vexillar basal 
lobes are extremely hairy, and their lower extremities fit into 
the hollow between alar limb and claw, so keeping out all 
useless insects and also keeping in the honey which is very 
abundantly secreted. Moreover, at first the pollen merely 
emerges as a ribbon-like mass (just as in Lotus), though after 
repeated depressions the stigma and anthers also emerge just 
as in A. aemula. Visitors: — Hymenoptera : (No. 192, an 
undescribed species). Diptera : a Bombylid, Pangonia angu - 
lata. 
Crotalaria eapensis, Jacq . (Fig. 56-60.) 
The flowers are of the same general type as those of 
Lupinus , but are marked by the extraordinary depth of the 
carina as seen from the side. The upper surfaces of the carina, 
moreover, are bulged out horizontally, and the alae having 
the same shape, embrace it very closely (Fig. 60) : their 
vertical superior margins are held together by the deep
