There are two alternating generations. The mosses, a side branch of the evolutionary tree, show the same features. The moss plant is the sexual generation; the capsule, parasitic on its parent, is the spore-bearer. The resting distribut- ing body is, in both mosses and ferns, the spore. § 11 The main line of evolution was that which led through the fern-like plants to the flowering plants. There was evolved a vegetative equipment suitable to life in moist soil and dry air; absorbing root-hairs,... roots, water-conducting tissues; light- absorbing leaves, borne aloft on a branching stem. The method of reproduction was gradually transformed till, in the flowering plant, a stage has been reached where the original equipment is barely recognisable. The plant is definitely emancipated from the medium in which it took its origin; fertilisation is now pre- ceded by pollination, and in providing for that the plant has evolved, in relation to the insect, the flowers we know to-day.
