INSECTIVOROUS PLANTS 211 
of which we find a round leaf, studded with bright-red 
hairs, on each of which glistens a tiny drop of sticky 
liquid. The flowers rise from the 
centre, a group of six or seven 
together in a loose panicle, all of 
a greenish white. If we place a 
dead midge or tiny fly (a bluebottle 
would be too much for the leaf 
and probably kill it) upon the leaf, 
and watch for a few minutes, we 
shall see a general movement of 
the hairs. They bend slowly over 
and hold the fly gripped in the 
gum. One after the other they 
curl inward upon it, until the fly 
is completely covered by them, 
z and they set to work to digest it 
at their leisure. The sensitiveness 
of these tentacles you will realise 
when you know that a piece of 
hair weighing one fifty-thousandth 
part of a grain will bring them promptly round to 
bear upon it, and get what nourishment they can.
