ORGANOGRAPHY AND GLOSSOLOGY. 



3. In the definite umbel or umbellate cyme the pedicels appear to start from the 

 same point as in the indefinite umbel, hut the central flowers open first, and the 

 outer pedicels are evidently the youngest and shortest : 



being a definite umbel, flowering centrifugally, it is truly '^'T*J<^ "^ f^"^^

is composed of a succession of independent axes, alternating to the right and left, 

 each terminating in an apparently sessile flower. 



5. The scorpioid cyme {Myosotis, fig. 164) is a 

 raceme which rolls up in a crozier shape, like the tail 

 of a scorpion ; it 

 is composed of a 

 succession of in- 

 dependent axes, 

 which do not al- 

 ternate right and 

 left, but form an 

 interrupted line, 

 which tends to 

 turn back upon it- 

 self; in this in- 

 florescence, the 

 bracts are usually 

 suppressed (fig. 

 165).

flowers are crowded, owing to the extreme shortness of the axes ; it is called 

 fascicled, when the axes are somewhat lengthened, and are regularly distributed
