BIOGRAPHICAL INDEX OF BRITISH AND IRISH BOTANISTS. 79 



The species which most frequently hybridise are necessarily 

 those whose period of flowering synchronises, but hybrids also occur 

 between species which do not usually flower at the same time, and 

 must have arisen from the rare accident of one or other of the 

 parents having flowered at an abnormal period. Such hybrids (of 

 which S. triandra-cinerea Wimm., not yet detected in Britain, is an 

 example) must always be rare. Amongst hybrids which have 

 occurred in Britain, l3ut which have usually escaped recognition, 

 are those between S. cinerea, S. aurita, and S. Caprea. Of these, 

 that between the first two seems to be by no means uncommon, but 

 the aurita-caprea and the cinerea-caprea hybrids are rarer. From 

 the close relationship of their parents, all of them may readily be 

 passed over. A number of others might be mentioned, but as on 

 this occasion I wish only to call the attention of British botanists 

 to the necessity for an increased study of the Willows, I abstain 

 from doing so. In conclusion, I may add that I shall at all times 

 be glad to examine good specimens.
