Lihacee—Tulipa. 497 
Stamens glabrous at the base. 
1. T. suaveolens. 
T. pubéscens is a hybrid 
Bulb-scales not woolly inside r between 1 and 2. 
2. T. Gesneriana. 
8. LL Tireica. 
4. T. pr&cox. 
| 5. T. Oculus-solis. 
6. T. Olustane. 
Bulb-scales woolly inside . 
7. T. sylvéstris, of which 
Stamens with a tuft of hairs at the base{ Celstdna, Géllica and Or- 
phanidea are varieties. 
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. 
sylvéstris, with yellow flowers, and the only one found in 
Britain; 7. Gdllica, very similar to the preceding, but dwarfer 
and having smaller flowers; 7. Celsiana, from the Mediter- 
ranean region, with yellow or orange flowers tinted with red 
extemally, but most likely only a variety of 7. sylvéstris; T. 
Oculus-sdlis, a common European species, flowers scarlet or 
red having a black spot encircled with yellow at the base of 
each petal; and 7. pré&cox, 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 7. Ges- 
neriana (fig. 244), a native of Western Siberia, and the parent 
KK
