. The elements of botany for beginners and for schools. Plants. SECTION 8.] INFLORESCENCE. 77. 213 further growth must be from axillary buds developing into branches. If such branches are leafy shoots, at length terminated by single blossoms, the inflorescence still consists of solitary flowers at the .summit of stem and branches. But it' the flowering branches hear only bracts in place of ordi- nary leaves, the result is the kind of flower-cluster called 219. A Cyme. This is commonly a ilat-topped or convex flower-cluster, like a corymb, only the blossoms arc from terminal buds. Fig. 211 illustrates the simplest cyme in a plant with oppo- site leaves, namely, with three flowers. The middle flower, a, terminates the stem ; the two others, b b, terminate branches, one from the axil of each of the uppermost leaves; and being later than the middle one, the flowering proceeds from the centre outwards, or is Centrifugal. This is the opposite of the indeterminate mode, or that where all the flower-buds are axillary. If flowering branches appear from the axils below, the lower ones are the later, so that the order of blossoming continues centrifugal or, which is the same thing, descending, as in Fig. 213, making a sort of reversed raceme or false ra- ceme,— a kind of cluster which is to the true raceme just what the flat cyme is to the corymb. 220. Wherever there are bracts or leaves, buds may be produced from their axils and appear as flowers. Fig. 212 represents the case where the branches, b b, of Fig. 211, each with a pair of small leaves or bracts about their middle, have branched again, and produced the branchlets and flowers c c, on each side. It is the continued repetition of this which forms the full or compound cyme, such as that of the Laures- tinus, Hobble-bush, Dogwood, and Hydrangea (Fig. 214). 221. A Fascicle (meaning a bundle), like that of the Sweet William and Lychnis of the gardens, is only a cyme with the flowers much crowded. 222. A Glomerule is a cy
