Such cases are illustrations of very simple flowers, though from the fact of their being aggregated together they ap- 3)ear more complicated, or rather the whole mass- of flowers, "the inflorescence," is commonly taken for the flower. In the case of the Willow and Poplar the -stamen-bearing flowers (Fig. 79) are on one plant, the pistil-bearing flowers on another (Fig. 80). In the Hazel-nut, or Melon, stamen-bearing flowers and pistil-bearing flowers are on the same plant. In many cases the flowers contain within the same envelopes both male and female organs, as in the Lily, although it by no means follows that the pollen of these so-called " hermaphrodite " flowei's really fertilises the germs in the pistil of the same flower. Very frequentlj', in order to secure adequate fertility and robust seedlings, the pollen from one flower lias to be conveyed to the stigma of quite a different flower, but one of the same species, and although close fertilisation may in some cases be the rule, yet an occasional cross is found to be advantageous in maintaining the health of the seedlings.

But the same thing is equally marked, though perhaps lesG obvious, in other cases; for instance, the ''blindness," as gardeners call it, of strawberries is due to the fact that the pollen and the stigma are not ripe and do not mature at the same time, and hence, although
