Solve this:

55. Inflorescence, which begins as a dichasial cyme and ends in a monochasial cyme, is called ​
(1) Cyathium          (2) Biparous 
(3) Verticillaster     (4) Thyrsus

Dear student

Please refer the solution below for the said query

The correct option is (3). 


The verticillaster inflorescence begins as a dichasial cyme and ends in a monochasial cyme.

In case of the monochasial cyme, the main axis ends in a flower. It then produces a single lateral branch at a time that terminates into flower. This branch again produces single lateral branch at a time which again terminates into flower and so on. 

In case of the the dichasial cyme, the peduncle ends by producing a terminal flower. This peduncle then forms two lateral branches each of which terminates in a flower.

Hope this information clears your doubt about the topic.

Regards
