m 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 if the flowering branches bear only
bracts in place of ordinary leaves, the result is the kind of
flower-cluster called

219. =A Cyme.= This is commonly a flat-topped or convex flower-cluster,
like a corymb, only the blossoms are from terminal buds. Fig. 211
illustrates the simplest cyme in a plant with opposite 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 raceme_,--a kind of cluster
which is to the true raceme just what the flat cyme is to the corymb.

[Illustration: Fig. 213. Diagram of a simple cyme in which the axis
lengthens, so as to take the form of a raceme.]

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 Laurestinus, Hobble-bush, Dogwood, and Hydrangea (Fig. 214).

neutral enlarged flowers round the circumference.]

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 cyme still more compacted, so as to imitate a
head. It may be known from a true head by the flowers not expanding
centripetally, that is, not from the circumference towards the centre.

223. The illustrations of determinate or _cymose_ inflorescence have
been taken from plants with opposite leaves, which give rise to the most
