 cymes, c c, in which the central flower expands first. Fig. 255 is a 



racemose cyme of Campanula, de- 

 veloped in a very irregular manner, 

 and giving rise to a peculiar mixed 

 inflorescence ; a' of is the primary 

 axis, ending in a flower, /', which 

 has withered, and giving off secon- 

 dary axes, a" a" each terminated by a 

 flower, and developed centripetally, 

 the lowest being most expanded. 

 These are anomalous cases and not 

 easily explained. Such mixed in- 

 florescences, partly definite and 

 partly indefinite, are by no means 

 uncommon. 



342. Sometimes flowers proceed 

 from what are called radical leaves ; 

 that is, from an axis which is so 

 shortened, as to bring the leaves 

 close together in the form of a clus- 

 ter. From such stems, floral axes 

 are pushed upwards occasionally, 

 bearing single flowers, or flowers 

 in umbels and racemes, as hi Primrose, Auricula, Hyacinth, &c. In 

 these cases, the name of scape is applied to the flowering stem.
