flower (Fig. 2, A 2) ; a third lateral branch, also rapidly 

 terminating in a flower, is in the same way borne in the 

 axil of a bract on this, and so on. 



Fig. 1. Stages in the development of a Monopodial Inflorescence 

 (raceme). A, young stage showing seven flower-buds, each in the axil of a 

 bract; there are four bud-scales at the base of the floral axis. B, the same 

 further advanced ; the lower flowers, numbered 1 3, nearly mature, and 

 several new buds developed at the apex of the elongating axis. C, the 

 raceme almost completed : the bud-scales fallen below. It will be seen 

 that there is only one primary axis, which continues to develope new 

 flowers near its apex in acropetal succession. 



As this process developes, the successive lateral seg- 

 ments each ending in a flower may straighten them- 

 selves out more and more (Fig. 2, B), until the appearance 

 of a common axis bearing flowers and bracts is produced. 

 The straightening out of the successive segments may 

 go so far as to produce the impression of a straight
