 VARIETIES OF TULIPS. 



The classification of the tulip is purely artificial and a complicated 

 subject, most seriously attempted in 1917 by a committee of the Hoyal 

 Horticultural Society of England.^ 



Tulips are first divided into early, late, or May flowering, which 

 need no definition, and species which are found native. The earlies 

 are divided into the Due van ThoU, which are very early dwarfs, the 

 singles, and the doubles. 



The lates are divided (1) into the Cottage subsection, which is a 

 catchall that is not definable except that its members do not belong 

 in the other groups ; (2) breeders which are self-colors ; (3) broken or 

 mosaic tulips, parrots which have laciniate floral segments; and (4) 

 double late tulips. 



1 Commonly called " narcissi."
