METHODS OF POLLINATION. 



Wind-pollination. — The chief thing all beginners 



have to do, in order to understand the ways of plants 



is to study their flowers, and 



to learn how it has come 



about that there are so many 



different sorts of sizes, shapes, 



colours, scents, etc. We shall 



see as we go along how this 



is due to the various means 



by which they get pollinated. 



There are, as we have 

 seen, three methods of secur- 

 ing pollination : by means of 

 the wind, by the aid of insects, 

 and by self-pollination. 



In the case of wdnd-polli- 

 nation, the stigmas are often 

 long and hairy, so that they 

 can easily catch the pollen 



and hold it. Look out for any grass that may be 

 in flower, and examine its two feather-like stigmas. 

 Cliffor'tia (Fig. 5) is a good example. This last-named
