LXIX. CORMS AND ROOTSTOCKS 447. True bulbs are madeup of scales. But there arecertain bulb-like bodies whichare solid throughout. Thegladiolus has them (Fig. 376).These are corms. 448. The corm which wasplanted in the spring is shownat the bottom (C). It hasbecome hard and lifeless, anda new large corm has formed above it, with roots of its Fig. of gladiolus. COBMS AND BOOTSTOCKS 359 448a. Gardeners say that crocuses lift out of the ground,and they advise that the bulbs be taken up every two or threeyears and replanted. Can the pupil suggest an explanation? 449. If there were only one new corm formedfor every old one, the plant would not increaseitself. The picture shows corn;iels, or spawn ^as the gardeners say, arising from the baseof the mother-corm, much as offsets arisefrom the house-leek (a. Fig. 376). If theseare removed and cared for, full-grown orflowering corms may be obtained in one ortwo years. , 450. We have found(43, 44, 45) that theearly flower-ing of treesis made pos-sible by thematurationof the bud ^- ., Short rhizome of agrimony. m the pre-vious season; and the twig stores up sufficientnutriment to push out the flowers, and, in mostcases, even to start off the leafy growth.
