96 NOMENCLATURE OF THE FLOWER. 



parts of the common stalk ; whilst in the latter, all the peduncles 

 proceed from a common centre. 



82. The only varieties of the corymb necessary to 

 be mentioned, are the simple and the compound. 



a. Simple when not divided into branches, as in penny-cress. 



b. Compound when it has branches, as in the narrow-leaved 

 everlasting. 



83. Fascicle : The fasciculus or fascicle, is a species 

 of inflorescence, in which the partial flowers on little 

 foot-stalks, arc variously inserted and subdivided, and 

 collected into a close bundle, level at the top. 



The sweet-william affords the most familiar illustration of a 

 fascicle. 



The fascicle differs from the corymb, in the little stalks coming 

 only from abont the apex of the general peduncle, and not from its 

 whole length from an umbel, on accdnnt of the stalks not pro- 

 ceeding from a common point- and from a cyme, in not having its 

 principal divisions umbellate. 



81. Tuft: The head or tuft is a term used to ex- 

 press the kind of blooming, in which several flowers 

 form a kind of ball or head, at the extremity of the 

 foot-stalks. 



The globe amaranth, bachelor's buttons, wild thjme, and som* 

 species of trefoil, will afford very good illustrations of the tuft. 



85. The most common varieties of the tuft are, the 

 globular, ovate, hispid, pedunculated, sessile, roundish, 

 and a few others. 



a. Globular of a round form, as in the common globe amaranth. 



b. Ovate in the form of an egg, as in the headed Liparia.
