Wkeu flowers thus arise singly from the axils of ordinary leaves, they are axillary aud solitary, uot collected into llower-clusters. 202. But wlieu several or many flowers are produced near each other, the accompanying leaves are apt to be of smaller size, or of different shape or character: then they are called Bracts, and the flowers thus brought together form a cluster. The kinds of flower-clusters of the indeterminate class have re- ceived distinct names, according to their form and disposition. They are principally Raceme, Corymb, Umbel^ Spike, Read, Spadix, Catkin, and Panicle. 203. In defining these it will be necessary to use some of the following terms of descriptive botany which relate to inflorescence. If a flower is stalkless, i. e. sits directly in the axil or other support, it is said to be If raised on a naked stalk of its own (as in Fig. 199) it is pedun- culate, and tiie stalk is a Peduncle. 204. A peduncle on which a flower-cluster is raised is a Common pedwicle. That which supports each separate flower of the cluster is a Partial peduncle, and is generally called a Pedicel. Tlie portion of the general stalk along which flowers are disposed is called the Axis of inforescence, or, when covered with sessile flowers, the Rliachis (l)ack-bone), and sometimes the Receptacle. Tlie leaves of a flower-cluster generally are termed Bracts. But when bracts of different orders are to be distinguished, those on the common pedun- cle or axis, and which have a flower ia their axil, keep the name of bracts ; and those on the pedicels or partial flower- stalks, if any, that of Bractlets or Bracteoles. The for- mer is tlie preferable Englisli name. 205. A Raceme (Fig. 200) is Ihat form of flower-cluster in which the flowers, each on their own foot-stalk or pedicel, are arranged along tlie sides of a common st
