Stamens with a tuft of hairs at the base -I Celsiana, Gdllica and Or-

The natural colours in the Tulip are yellow, crimson, and 

 violet of different hues, to which may be added white, which, 

 however, is only a decoloration. They are either isolated or 

 blended one with the other in the most diverse proportions, or 

 they exist separately and distinctly in the same flower in the 

 form of bands or spots. Under cultivation the original single 

 flowers have produced semi-double and very double varieties, 

 in which not only have the stamens become petaloid, but the 

 number of the perianth-leaves has also been greatly increased. 

 And then there are some double varieties with the perianth- 

 leaves torn or fringed in the most curious and monstrous manner. 



All the species and varieties of Tulips flourish under our 

 climate and produce their flowers in early Spring, but not all 

 at the same time. There are early and late and intermediate 

 varieties, which permits of having them in bloom for a month 

 or more, in a well-assorted collection. 



The following are amongst the rarer cultivated forms : T. 

 sylvestris, with yellow flowers, and the only one found in 

 Britain ; T. Gdttida, very similar to the preceding, but dwarfer 

 and having smaller flowers ; T. Celsiana, from the Mediter- 

 ranean region, with yellow or orange flowers tinted with red 

 externally, but most likely only a variety of T. sylvestris ; T. 

 Oculus-solis, a common European species, flowers scarlet or 

 red having a black spot encircled with yellow at the base of 

 each petal ; and T. prcecox, perhaps a variety of the preceding-, 

 of tall and robust habit, with crimson flowers. 



We now come to the species which have produced all or 

 nearly all of the florist's varieties, so extensively employed in 

 Spring gardening, and also for forcing in pots. First is T. Ges- 

 neriana (fig. 244), a native of Western Siberia, and the parent
