The tuber, corji and bulb are analosous forms approaching by degrees to tho character of the bud, which consists of a little axis bearing a covering oJ scales. In the tuber the axis is excessively developed whUe the scales are reduced to mere linear points. In the corm the analogy is far more 65 evident, for the axis is less excessive and the scales more manifest, and lastly in the bulb the analogy is complete, or '^ ⢠*"â¢" * overdone, the scales often becoming excessive. CHAPTEE VI. THE LEAF-BUD. 195. It is but a step fi-om tlie study of the bulb to that of the leaf-bud. Buds are of two kinds in respect to their contents; the leaf-hud containing the rudiments of a leafy stem or branch, the flower- hud containing the same elements transformed into the nascent organs of a flower for the purpose of reproduction. 196. The leap-bud consists of a brief, cone- shaped axis with a tender growing point, bearing a protecting covering of imbricated scales and incip- ient leaves. 65. Branch of pear tree.
