makino^ four distinct colors ! Q. E. D. — These last colors 

 are accounted for hy the disappearance of the yellow pig- 

 ment, which leaves a white basal color and changes scarlet 

 to crimson. The yellow eye of a white tulip is apt final I3' 

 to fade to white. I have also observed a similar red zone 

 in a white Ron)an Anemone. 



Prof. M. I. Newbigiu mentions what appears to be a 

 mystery to him concerning honey guides, A'iz. : the fact that 

 they occur sometimes where there are no nectaries. No 

 examples are given, but the professor might have had in 

 mind a flower like the Oriental Poppy. 



Example 11. — This scarlet poppy* is one of the largest 

 of flowers known, l^eing quite seven inches in diameter, and 

 on each of its four broad, flaming petals, near the l)ase, 

 there is a black spot one inch in diameter. As Prof. N. 

 remarks, there is not the slightest evidence of any nectar 

 anywhere on the petal and apparently none in any other 

 part of the flower. What then are the spots for, and how 

 were they produced ? 



Of course, we have no record of the history of the flower 

 and of what colors it flaunted long ago in the garden of 

 P^den, so one must theorize somewhat, and our theory is 

 just what has been stated regarding the tulip ; evidently the 

 flower has changed from its original color which was some 

 shade of purple, and the bees or some other Eastern insect 

 visited the flower just as they do now for the nectar that 

 the anthers afford, precisely as the bees visit the anthers of 

 the rose in these days. As they revolved around among 

 the numerous stamens of the same inky hue as the spots, in 

 clinging to the outermost, their backs rubbed against the 

 walls of the petals at the precise place of the spots, which 

 is central on the petal and slightly depressed. The sta- 

 mens are weak and inclined to drooj), so that the weight of 

 the bee throws him, or if he loses his hold, he falls on to
