cyme ; when it has its flowers on pedicels of nearly equal length, 

 as in the Campanula (fig. 414), as a racemose cyme; or when 

 it assumes the form of a panicle, as in the Privet (j^^. 415). as 

 a panicled cyme. These forms of cymes are readily distinguished 

 from the true racemes, &c., by the terminal flowers opening 

 first, and the others expanding in succession towards the base, 

 or in a centrifugal manner ; while in the true raceme the flowers 

 open first at the base and last at the apex, or centripetally.

Besides the true cyme and its varieties mentioned above, 

 other kinds have also received particular names, as the Helicoid 

 Cyme, the Fascicle, the Glomerule, and the Verticillaster, which 

 we must now briefly describe. 



b. Helicoid or Scorpioid Cyme.— This is akind of cyme in which 

 the flowers arc only developed on one side, and in which the 

 upper extremity is more or less coiled up in a circinatc or spiral 

 manner, so as frequently to resemble a snail, or the tail of a 

 scorpion, and hence tlie names of helicoid or scorpioid by which 

 it is distinguished. It is also sometimes called a circinate or
