364 Scott Elliot*— On the Fertilisation of Sotitk 
in diameter at the actual throat ( t in figure). The anthers 
are inserted just below the entrance and their tips converge 
or arch together. Behind and above each anther is a small 
brush of hairs (developed on the corolla), and these hairs form 
a sort of roof protecting the pollen from rain. The style 
ends in a flat top (si) upon which the pollen is shed. The 
stigma is below this, and in its lower part secretes a sticky 
substance. When a butterfly stands on the spreading limb 
and inserts its proboscis, the latter slips down the tube along 
and against the inside of the corolla-tube without touching the 
pollen-mass, but on withdrawing its proboscis the latter is 
straightened and passes over the viscid convex stigma, and as 
this involves effort it is forced to slip between two anthers, 
and so catches and brings out a good deal of pollen. This 
can be clearly proved by introducing a bristle in the flowers. 
Abundantly visited by numerous (at least eight) species of 
butterflies. — Fort Dauphin. I could not see any motion of 
the staminal filaments as found by Wilson (Muller, No. 781) 
for V. minor, which has also been beautifully described by 
Charles Darwin (Muller, No. 153). 
Gomphoearpus arborescens, R. Br . 
Visited by small mosquito-like Diptera in great abun- 
dance. — Table Mountain, June. 
Camptoearpus crassifolius, Dene., No. 2871, Herb. Scott 
Elliot (Fig. 98). 
The corona is in the form of a cup-like ring about a line 
high, but opposite the stamens it is prolonged upwards into 
conical teeth about one and a quarter of a line in length. 
The filaments of the stamens are united to the coronal cup 
and as their anthers, as usual, lie upon the mushroom-like 
head of the style, a narrow passage only is left underneath 
the overhanging head of the latter c, c (see Fig. 98). 
The retinaculum consists of a rather long sticky disc which 
is placed horizontally on the flat lower surface of the style- 
head, and is therefore inclined at an angle of 6o° with the 
appendices of the anthers to which it is attached (see Fig. d)»
