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 Miller, are butterflies. It 
cements its pollen to their tongues, and thus com-
