294 BULBS AND TUBEROUS-ROOTED PLANTS. 



.T. australis (Celsiana). A native of Siberia; 

 flowers star-shaped, deep yellow, flat, opening nearly six 

 inches across ; very fragrant. 



T. Greigii. A species or recent introduction, na- 

 tive of Turkestan, from whence it was introduced in 

 1873, by Herr Max Leichtlin, who says the bulbs are so 

 extremely hardy that they will withstand freezing and 

 thawing with impunity, and that even when the leaves 

 are half grown they will endure a temperature as low as 

 that of zero without any protection. The plant is a vig- 

 orous grower, attaining a height of from nine to fifteen 

 inches, bearing a solitary flower from four to six inches 

 in diameter, goblet-shaped, generally of a vivid orange- 

 scarlet color, with black spots on yellow ground at the 

 base of the petals.. The foliage is broad, lively green, 

 heavily spotted with brown. A very desirable species. 



T. silvestris. Of this there are several varieties, 

 with white, yellow or rose colored flowers, some of which 

 are slightly shaded with purple ; delightfully fragrant ; 

 common in France and many other parts of the continent. 



T. oculus-solis. This species is nearly allied to 

 T. Gesneriana, but is easily distinguished by its black 

 center, which gives it the popular name, Sun's Eye. 

 The flowers are always erect, and without fragrance ; 

 opening so as to form a large cup. Native of Northern 

 Italy, and some parts of France. 



T. persica. A native of Persia, resembling the 

 Due van Thol Tulip. 



Cultivation of the Tulip. We usually consider 

 the Tulip to be a hardy bulb, capable of enduring 

 almost any amount of freezing without injury. In our 

 changeable climate there is, however, some danger of 

 injury from contraction and expansion of soil, caused by 

 freezing and thawing. It is, therefore, better to protect 

 the bulbs by a slight mulching of leaves, sufficient to 

 prevent the frost from penetrating the earth below the 

 base of the bulbs.
