Variegation 2. — There is a slight tendency to blue, mani- 

 fested in the anthers of the same original type, which by 

 the stimulus of constant visits of bees is increased and the 

 color deepened, so that besides the original yellow and the 

 white, one may occasionally see an anther which has turned 

 blue, and the darker the flower, that is, if it lie a scarlet 

 for instance, the surer one is to lind a l)lue anther, and not 

 "only this, but the yellow eye changes to blue, and the same 

 bees w^hich were responsible for the yellow eye are also 

 responsil)le in a measure for the dark cobalt-l)lue of T. Ges- 

 neriana and for the black pollen dust changed from golden 

 3'ellow. 



There is a very attractive variety of tuh'p known as the 

 Kaiser Crown, of yellow and scarlet colors ; its peculiarity 

 is in the two ways of variegation. The scarlet which suf- 

 fuses the yellow foundation color runs on the outside, from 

 base towards the tip ; on the contrary, that on the inside is 

 the reverse, that is to say, the scarlet color extends hori- 

 zontally on each petal, forming a central scarlet zone in the 

 yellow tlower-cup. The former is the natural method ; the 

 latter is the result of insect agency, and is, 



Variegation 3. — The same l)ee while giving his undivided 

 attention to the anthers, owing to the proximity of the 

 erect petals, is ai)t, in going the rounds of the stamens, to 

 rub his back against them, wnth the result that just where 

 it touches is left a more or less distinct scarlet band within 

 the petals at the exact height of the anthers I This feature 

 being noticed by the Dutch tlorists was doul)tless seized 

 upon and hence the beautiful variety. 



This singular zonal marking cannot be seen in every 

 yellow flower. It is more apt to l)e found in one which 

 has a tendenc}^ to a scarlet or red color, seen perhaps on 

 the outside, and the stimulus of the insect awakens it 

 within. In like manner and b}^ the same agency, the writer 

 has seen a wdiite tulip with a crimson zone on the inside, 

 the "eye" still remaining yellow and the anthers blue.
