African and Madagascar Flowering Plants. 361 
hairs united side by side, we have no difficulty in understand- 
ing how it arose. (See also Fritz Muller in Muller, No. 353, 
Bentham in Muller, No. 84.) Visitors:— Near Durban, Hyme- 
noptera: Nos. 385,365,367,366,368^11 large bees about the size 
of a Bombns , and sucking legitimately® Also Nos. 366, 369, and 
370 all attempting to obtain the honey by inserting their pro- 
boscis in the upper slit of the corolla. I found the basal part 
of the style very hairy, probably an attempt to prevent this 
robbery. At Fort Dauphin, Madagascar, Xylocopa olivacea , 
Elis Romendi , Apis mellifica , and another (No. 617). 
Lepidoptera : Thorania , Durban, Nos. 372, 380, and another 
sp. Fort Dauphin, a large moth, No. 615. Coleoptera : Durban, 
No. 371. 
Goodenia. 
I have been much struck by the exact similarity of the 
description of this genus, as given by Mr. Hamilton (Macleod, 
Nos. 180 and 186), with the preceding; but neither Mr. 
Hamilton nor Mr. Haviland seem to have observed the 
fertilisation by insects. 
Lobelia. 
The fertilisation of Lobelia Erinus , L., has been very 
thoroughly described by Farrer (Muller, No. 240). Lobelia 
decipiens agrees closely with it. I found on the lower lip 
two ridges ending in a slot or groove, which affords a firm 
foothold for the bee. (Cf. Trelease, Muller, No. 727.) Apis 
mellifica was busily visiting the flowers (near East London) ; 
it pushes its head half-way down the tube, and, on retiring, 
its head and thorax are covered with a broad band of pollen ; 
in so doing it seemed to me that it pushed the bases of the 
lower filaments aside and so caused a thrusting down of the 
anther-cylinder on the circle of style-hairs. (Cf. Delpino, 
Muller No. 360 ; and Urban, Muller No. 75 1 *) 
Lobelia eoronopifolia, L . 
Also visited by a Hymenopteron at East London. 
Erica leeana, Ait. 
The corolla is of an unusual length, viz. about 9 lines.
