Roses and Apples AS 
The Avens considers mammals and even man more 
useful even than birds in this connection, because 
birds want bribing. After its style has served its 
proper purpose the Avens hardens it into a delicate 
bit of flexible wire, turns its bent tip into a more 
definite hook with polished surface, so that it may 
be warranted to pass imperceptibly through any 
textile, or to cling to fur or wool. The receptacle 
and its nutlets have developed into a 
relatively large mop-head of bristlng ‘9 
hooks, which cannot be touched by i 
coat of sheep, rabbit, dog, or cattle (GS

with its contained seed. Try this for 
yourself by rubbing such a fruit-head :

that is the reason why they are AIRS

only to be dislodged by firm pres- Agrimony

way between the stems of the hedgerow, just the 
right kind of pressure is exerted, and the nutlets 
drop off. The bright little Agrimony (Agrimonia 
eupatoria) carries its two nutlets in the hardened 
calyx, whose summit is set around with small hooks 
which serve a similar purpose. 
Now if we turn to the Brambles, which are also 
Roses, we may get a clue to the probable stages by
