LXVIII. BULBS, BULBLETS, AND BUDS 438. We have now foundthat plants propagate them-selves by both sexual and sex-less means, for seeds are theproduct of a sexual process,whereas most spores are not; 439. A bulb of an Easterlily, taken after the floweringperiod is past, is shown in It is breaking up intoseveral parts; and the gar-dener knows that each of theseparts is a new bulb, andis capable of multiplying theplant. 440. If we cut the bulbin two lengthwise, we find astructure like that shown inFig. 369. There is a main. Pig. bulbs. 354 LUSSOlfS WITH PLANTS axis, and separate bulbs (orbulbels) are forming at ab, c, d. Each of these bulb-els, as well as the mother-bulb, is seen to be only amass of thickened scales,and these scales aretransformed leaves.
