Systematic Position and Bennettitalean Flowers

Systematic Position:-
Kingdom:- Plantae
Division:- Gymnospermae
Order:- Bennettitales
Family:- Cycadeoidaceae
Genus:- Cycadeoidea

Bennettitalean Flowers:-
> The reproductive organs were organised in the form of hermaphrodite (e.g. Cycadeoidea) or unisexual (e.g. Wielandiella) “flowers”, which in turn were protected by many bracts.
> The ‘flowers’ developed in the axil of leaves.
> Male reproductive organs were borne in a whorl. They were free or fused, entire or pinnately compound.
> Microsporangia were present abaxially in the form of synangia.
> Microsporophyll’s sometimes surrounded megasporophylls forming hermaphrodite “flowers”.
> Ovules were numerous and stalked and borne on a conical, cylindrical or dome-shaped receptacle.
> Many inter-seminal bracts were present on the ovule containing receptacle.
> The scales or bracts were united at end to form shield through which micropyle protrudes.
