We can distinguish bulbs from normalbuds, then, by saying that bulbs directly give riseto other bulbs which produce plants; and theseplants may produce bulbs directly, or may bear. Fia. 374. Fig. 375. Winter bud of anacharis. Winter bud of myriophyllum. seeds which produce plants which produce give rise to growing shoots which may pro-duce flowers and seeds, and these seeds produceplants which produce buds. We cannot carry thisdistinction far, however, because bulbs not onlyproduce other bulbs by lateral growth, but at thesame time produce a growing vertical shoot oraxis; and we shall find, also, that buds mayseparate from the parent in essentially the sameway that the bulblets of the tiger lily do. Thepoint is that pl&nts may propagate by either sex-ual or asexual means, or by both means. 358 LUSSONS WITff PLANTS 446. If one were to pull the water-weeds fromthe drift on the margins of lakes and ponds inlate fall, he would find many of the strands withlarge bud-like bodies at the ends (Figs. 374, 375).These buds drop to the bottom of the pond, andin spring vegetate and give rise to new plants.
