338 Scott Elliot . — On the Fertilisation of South 
depression the style and stamens emerge without any explo- 
sion ; the petals return to their original position by elasticity. 
Visitors : — Apis mellifica very abundant and effecting fertilisa- 
tion, also Diptera. — Muizenberg. 
Sida earpinifolia, DC. 
The styles are at first erect and well above the anthers, 
so that cross-fertilisation is probable; subsequently they 
curve downwards so that in the final state they way touch 
the pollen and effect self-fertilisation. Honey appears to be 
secreted by the thickened bases of the petals and staminal 
sheath. The carpels separate into two short, sharp, diverg- 
ing horns, adapted to catch in the fur or feathers of animals 
and so disperse the seeds. Visitors : — Apis mellifica , ab. 
— Fort Dauphin. 
Hibiscus Trionum, L. 
Visitors : — Apis mellifica and two kinds of Diptera, all 
sucking (see Macleod, No. 337). 
Abutilon albidum, L. (Fig. 10.) 
The corolla tube is narrower at the throat than lower 
down, so that the distance between the anthers (when de- 
hiscing) and the nearest petal is usually about one or two 
lines ; in older flowers the stigmas take up a position exactly 
the same distance from the petals. Honey is secreted by the 
cupular base of the sepals, and fills the cavity below the petals 
and inside the calyx tube ; entrance to it is obtained by oval 
apertures between the claws of the petals. Visitors : — Apis 
mellifica abundant, usually crawling down the corolla and so 
effecting cross-fertilisation, but sometimes crawling over the 
mass of stamens in which it may effect either cross or self- 
fertilisation (cf. Fritz Muller on Abutilon , ‘ Embira branca,’ 
Muller, No. 557). 
Dombeya dregeana, Sond. 
The five staminodes are curved outwards, and form a sort 
of arcade between themselves and the petals, round which an 
insect must crawl to obtain the honey secreted by the petaline
