their widespread attitude, and the indigestible horny 
portions of its last meal are still to be seen in the 
centre of the leaf. 
There is little of an interesting character known 
concerning the flowers of the Sundew, which are 
small, the white petals being but little longer than 
the sepals, and both stamens and pistil maturing at 
the same time. In many eases these flowers do not 
open, or open very slightly, but the pollen-grains 
send out shoots which reach the stigmas and so 
fertilise the seed-eges. 
The leaves of the three native species present 
variations in form and habit that probably refer to 
some differences in their victims. The round leaves 
of Drosera rotundifolia are extended at right angles 
with the rootstock; the spoon-shaped leaves of 
D. intermedia hold themselves erectly, and the 
longer, more slender ones of D. anglica are borne 
almost erectly. There is a striking parallel in two 
species of Plantain: Plantago media has broad, more 
or less rounded leaves, spread in rosette fashion on 
the soil, whilst P. maritima has long, slender, lance- 
shaped leaves which are borne nearly erectly. Sir 
John Lubbock considers that the attitude is deter- 
mined by the shape of the leaves, and this may be so; 
but no doubt in the case of Drosera the difference 
would enable those with long leaves to catch more 
low-flying insects, whilst the flat, round leaves would 
be more likely to capture those that crawled over 
them.
