The centre of the female blossom is occupied, you will observe, by several twisted and wriggling arms, the upper sur- face of which is more or less sticky. This surface forms the receptive portion, or mouth of the flower, on which grains of pollen must be duly deposited before the embryo seeds in the cap- sule below can begin to swell and develop.

The centre of the female blossom is occupied, you will observe, by several twisted and wriggling arms, the upper sur- face of which is more or less sticky. This surface forms the receptive portion, or mouth of the flower, on which grains of pollen must be duly deposited before the embryo seeds in the cap- sule below can begin to swell and develop. On the other hand, the centre of the male llower, as seen in No. 4, is occupied by a set of very different organs, the stamens or pollen-bags, whose busi- ness it is to produce and shed the fertilis- ing powder. Without pollen to start them, the seeds are useless. In the wild state, any winged insect which visits the plant is likely to aliglit fust on the lip or platform of one or other of the outer male flowers. In his search for honey, which is secreted by the plant at the base of the petals on purpose to allure him, the flying visitor dusts himself over abund- antly, though unconsciously, with grains of pollen from the very numerous little sacs which are placed there in a convenient situation with that.
