groove in the latter, and, secondly , by the auricles of alae and 
carina which fit over one another behind. (The carinal edges 
are also swollen where they meet above the staminal sheath.) 
On depression the stamens and style emerge and cannot 
return within the carina. — Cape Town. 
Amphithalea ericaefolia, E. & Z. (Figs. 31-34.) 
The sides of the vexillum are revolute and the lateral 
sepals are tucked in behind them, as in Liparia , while the 
anterior sepal steadies and supports the carina. There is a 
large triangular peg on each side of the carina which fits into 
a deep socket-like groove of the alae ; the margins of the alae 
above this socket are thickened, while their lower margins 
turn inwards below those of the carina. Hence the alae and 
carina are quite inseparable. On depression the stamens and 
style emerge. The hairs on the ovary keep off small insects. 
Borbonia cordata, Z. (Figs. 35-37*) 
This flower is perhaps nearest in all essential points to 
Lotus (cf. Muller, p. 167). There are, however, some very 
marked differences in which it approaches very closely to 
some of the Aspalathi. The vexillum, e. g., has a long and 
arched claw, and the basal lobes of the limb are so turned down 
that they press upon the superior surfaces of the alae. The 
latter have rather deep longitudinal grooves corresponding to 
these points of depression (i.e. of the vexillum), and their lower 
surfaces are also bent inwards along their whole length and to 
such an extent that, at the junction of the alar claw and limb, 
the surfaces of the alae are entirely horizontal, and are in 
contact below the carina. The latter has a marked lateral 
bulging on either side, with a groove above and below, and 
this is closely embraced by the alae on both sides. Hence, on 
depression, alae and carina move together (the alae bending 
at the horizontal surface near the junction of limb and claw). 
The five outer anthers push up the pollen as in Lotus , and the 
odd stamen grows with them (sometimes showing an inter- 
mediate form of anther). The stigma and then the pollen (as 
a conical mass round the style) emerge on depression. The
