Vedclass · Answer

(B) Bentham and Hooker classified Polypetalae into three series: Thalamiflorae,Disciflorae,and Calyciflorae. $1$. Thalamiflorae includes flowers with a convex or conical thalamus and superior ovary (e.g.,$Ranunculaceae$). $Catharanthus$ $roseus$ belongs to the family $Apocynaceae$,which is classified under Gamopetalae,not Polypetalae. $2$. Disciflorae includes flowers with a prominent disc (e.g.,$Rutaceae$ like $Citrus$ $limon$). $3$. Calyciflorae includes flowers with a cup-shaped thalamus and perigynous or epigynous ovary (e.g.,$Rosaceae$ like $Rosa$ $indica$). $4$. Inferae is a series under Gamopetalae,not Polypetalae,and includes $Helianthus$ $annuus$ $(Asteraceae)$. Since the question asks for the incorrect pair based on the classification of Polypetalae,$Catharanthus$ $roseus$ is incorrectly placed as it belongs to Gamopetalae.

Identify the incorrect pair from the following based on Bentham and Hooker's classification of Polypetalae:
