ular cymes. But the Rose, Cinquefoil, Buttercup, etc., with alternate
leaves, furnish also good examples of cymose inflorescence.

224. =A Cymule= (or diminutive cyme) is either a reduced small cyme of
few flowers, or a branch of a compound cyme, i. e. a partial cyme.

225. =Scorpioid= or =Helicoid Cymes=, of various sorts, are forms of
determinate inflorescence (often puzzling to the student) in which one
half of the ramification fails to appear. So that they may be called
_incomplete cymes_. The commoner forms may be understood by comparing a
complete cyme, like that of Fig. 215 with Fig. 216, the diagram of a
cyme of an opposite-leaved plant, having a series of terminal flowers
and the axis continued by the development of a branch in the axil of
only one of the leaves at each node. The dotted lines on the left
indicate the place of the wanting branches, which if present would
convert this _scorpioid cyme_ into the complete one of Fig. 215. Fig.
217 is a diagram of similar inflorescence with alternate leaves. Both
are kinds of _false racemes_ (219). When the bracts are also wanting in
such cases, as in many Borragineous plants, the true nature of the
inflorescence is very much disguised.

Chickweed.]

226. These distinctions between determinate and indeterminate
inflorescence, between corymbs and cymes, and between the true and the
false raceme and spike, were not recognized by botanists much more than
half a century ago, and even now are not always attended to in
descriptions. It is still usual and convenient to describe rounded or
flat-topped and open ramification as _corymbose_, even when essentially
cymose; also to call the reversed or false racemes or spikes by these
(strictly incorrect) names.

227. =Mixed Inflorescence= is that in which the two plans are mixed or
combined in compound clusters. A _mixed panicle_ is one in which, while
the primary ramification is of the indeterminate order, the secondary or
ultimate is wholly or partly of the determinate order. A contracted or
elongated inflorescence of this sort is called a THYRSUS. Lilac and
Horse-chestnut afford common examples of mixed inflorescence of this
sort. When loose and open such flower-clusters
