But some of them are commonly flower-buds : in the Eed Maple, only the middle one is a leaf-bud, and it does not grow until after those on each side of it have expanded the blossoms they contain. 60. Sorts of Buds. It may be useful to enumerate the kinds of buds which have been described or men- tioned. Tliey are Terminal, when they occupy the summit of (or ter- minate) a stem. Lateral, when they arc borne on the side of a stem; of which the regular kind is the Axillary, situated in the axil of a leaf. These are Accessory or Supernumerary, when Ihey are in addition to the normal solitary bud; aud these are Collateral, when side by side; Superposed, when one above another; Extra-axillary, when they appear above the axil, as some do when superposed, and as occasionally is the case when single. Naked buds j those which have no protecting scales. Scaly buds; those which have protecting scales, which are altered leaves or bases of leaves. Leaf-buds, contain or give rise to leaves, and develop into a leafy shoot. Floicer-buds, contain or consist of blossoms, and no leaves. Mixed buds, contain both leaves and blossoms. 61. Definite annual Growth from winter buds is marked in most of the shoots from strong buds, such as those of the Horse-chestnut and Hickory (Fig. 72, 73). Such a bud generally contains, already formed in miniature, aU or a great part of the leaves and joints of stem it is to pro- duce, makes its whole growth in length in the course of a few weeks, or som
