Botany. INFLOEESCBNCE. fig. 135). In the Stock and many allied plants, the inflorescence is at first a corymb, but changes to a raceme as the primary axis lengthens. 3. In the umbel {umbella) the secondary axes are equal in length, and starting from the same point, flower at the same height, diverging like the rays of a parasol; it is a raceme of which the primary axis is reduced almost to a point. The umbel is simple {sertulum), Mvhen the secondary axes flower {Cherry, fig. 186) ; it is com- pound, when these bear umbellately arranged tertiary axes, called partial umbels [umbellulw. Fennel, fig. 137; Carrot, fig. 138; Fool's Parsley, fig. 139). The bracts, which in most racemes spring, like the pedicels, from different heights, in many umbelliferous plants rise on a level, like the secondary and tertiary axes, and form a whorl. The name invohicre [involucrum) is given to the bracts at the base of the umbel.
