Vedclass · Answer

(C) In Bentham and Hooker's system of classification,the subclass $Polypetalae$ is divided into three series: $Thalamiflorae$,$Disciflorae$,and $Calyciflorae$.$1$. $Thalamiflorae$: The thalamus is dome-shaped or conical,and the ovary is superior.$2$. $Disciflorae$: $A$ cushion-like disc is present on the thalamus,and the ovary is superior.$3$. $Calyciflorae$: The thalamus grows upwards to form a cup-shaped structure (hypanthium) around the ovary,and the floral parts are perigynous or epigynous. Thus,the cup-shaped thalamus is a characteristic feature of $Calyciflorae$.
