MORPHOLOGY 



does not elongate indefinitely as in the racemose 

 type, but terminates in or is defined by a flower, and 

 produces below it one or more secondary axes, each 

 of which in its turn terminates in a flower. The 

 principal forms of it, as indicated in Chapter IX, 

 are: (i) false dichotomy, or dichasium, or Bi- 



PAROUS cyme; (2) HELICOID, UNIPAROUS, Or ONE- 

 SIDED CYME; (3) SCORPIOID Or ALTERNATE-SIDED 



CYME. The cymes may 

 take the apparent forms 

 of racemose inflores- 

 cences, when they are 

 distinguished as cy- 

 mose corymb, cymose 

 umbel, cymose panicle,, 

 &c. In many cymose in- 

 florescences the flowers 

 are crowded together 

 in clusters, the central 

 flowers of which open 

 first and the other 

 flowers, open in suc- 

 cession from the centre 

 towards the circumfer- 

 In the cymose type the 

 branching is essentially sympodial. 



The lal-bharenda. Coral plant {Jatropha multifida), 

 ghentu {Clerodendron), and Pink {Dianthus chinensis, 

 L.) are examples of dichasium ; hati-soonrh {Helio- 

 tropium indicum) (fig. 73) and Hyoscyamus niger are 

 examples of scorpioid cyme; most plants of the Solanum 

 or Potato family are examples of helicoid cyme. In 

 rang-chita (see fig. 1 14) and teshira-monsha (see fig. 

 232) there is a cymose head of flowers (cyathium) 

 embraced within an involucre of one or more calyx-
