into five slender points. Its deep pink-veining 

 suggests nectar, and the insect visitor is not dis- 

 appointed, for at its base are five nectar-bearing 

 glands. These stand in a ring around the pistil, 

 and in a larger circle, outside the ring of honey- 

 glands, are the five stamens. The anthers stand 

 erect, and in shape are like arrow- or spear-heads 

 (Fig. 85). Corresponding to the two points at 

 the base of a spear-head there are, at the base 

 of each anther, two little hard horns, and the 

 stamens ring so closely about the pistil that horn 

 is beside horn all around the circle. 



On the inside of the corolla, near its base, are 

 five triangular callosities, with their points up. 

 These are placed in such a way as to alternate, 

 with the stamens, and stand a little below them, 

 so that the two hard points at the bases of two 

 neighboring anthers, and the hard tip of the cal- 

 losity three little horns come together like the 

 teeth of a trap. There are no fewer than five 

 places inside the flower's cup where these traps 

 are set, and inside the circle of traps are the 

 glands which contain nectar (Fig. 85). 



The blossom is visited by bees and flies, but its 

 favorite guests, says Muller, are butterflies. It 

 cements its pollen to their tongues, and thus com-
