INFLORESCENCE, the arrangement of the flowers on the axis, or the ramification of the floral axis, composed of the rachis, which forms the stalk supporting the flower or cluster of flowers, called the peduncle. A flower having no stalk is called sessile. The floral axis may be shortened, assuming a flattened convex or concave form and bearing numerous flowers as in the artichoke, daisy, etc. There are two distinct types of inflorescence (I) inde terminate, indefinite or axillary and (2) determinate, definite or terminal. A third series of inflorescence is termed mixed. In the compouna indefinite inflorescence the lateral shoots develop cen tripetally upon a primary axis into a group of racemes or corn pound racemes. See FLOWER.
