THE CYMOSE TYPE.

composition best, on close examination. A condensed but less 

 capitate cyme, or cluster of cymes, was called by Roeper and 

 DeCandolle a FASCICLE ; and this terminology has been much 

 adopted. It is properly enough 

 said to be a fascicle, which, as 

 used by Linnaeus and others, 

 means a bundle, or close collection 

 of parts, whether leaves, pedun- 

 cles, or flowers ; but a fascicle is 

 not necessarily a cyme (274) , nor is 

 there need of a special substantive 

 name for a compact cyme, which 

 may either be simply so called or 

 it may pass into the glomerule. 



281. Botryoidal forms of Cymose 

 Type, or False Racemes, &c. The 

 regular cyme seldom continues 

 with all its ramifications. In 

 Fig. 292, after the second forking, 

 one of the two lateral peduncles 

 mostly fails to appear, and in some 

 parts one of the bracts also ; and ultimately the lateral peduncle 

 present is bractless, like the central, therefore equally incapable 

 of further ramification, being reduced to a pedicel of a single inter- 

 node. This suppression some- 

 times begins at the first fork- 

 ing or at the very base ; and, 

 when followed throughout, it 

 reduces a biparous or dichoto- 

 mous cyme to one half, and, 

 converts this half (when the 

 axis straightens) into the sem- 

 blance of a raceme if the 

 flowers are pedicelled, or of a 

 spike when they are sessile. 

 Fig. 296 is a diagram of such an inflorescence as that of Fig. 292, 

 with one lateral branch uniformly suppressed at each division, the 

 wanting members indicated by short dotted lines. Cases exem- 

 plifying this occur in portions of the inflorescence of some of our 



FIG. 294. Plant of Cornus Canadensis : flowering stem bearing a cluster of leaves 

 above, then continued into a peduncle, and terminated by a glomerule of very small 

 flowers; this subtended by a colored and corolla-like involucre of four bracts. 295. One 

 of the flowers taken from the glomerule, enlarged. 



FIG. 296. Uniparous cyme or sympodial false raceme, with opposite leaves or bracts.
