Question

Which family is included under coronariae?
A. Amaryllidaceae
B. Arecaceae
C. Liliacea
D. Typhaceae

Answer 1

Hint: Coronariae meaning crown or garland is commonly the family of flowers . It means the flowers that are used to grow in garlands. It is the family of monocotyledons. It is the suborder that includes family in it .The family that produces flowers comes under suborder coronariae.

Complete answer:
The common name given for the suborder of flowering plants is Lillianae. In Bentham and Hooker classification system series coronariae belong to the angiosperms that are flowering plants and monocots. It is characterised by having perianth ( calyx and corolla get fused with each other ) . They have a superior ovary .
Now let us match these characteristics with the given options:-
Amaryllidaceae :- in this the position of ovary may be superior or inferior . So they are not included under coronariae . They come under monocots and order asparagales.
Arecaceae :- the calyx and corolla may be fused or not. So they are not included under coronariae but they are included under arecales. So this option is not correct.
Liliacea :- the calyx and corolla are fused and the ovary is always superior . So they are included under suborder coronariae. Thus this option is correct.
Typhaceae :- it has 3 to 6 perianth but coronariae have 3+3 perianth . Thus this option is not correct. It is included under order poales.

Note: Coronariae is a flowering order that includes family liliaceae. It has petal six ( 3+3) that often remains united in a tube and possesses valvate aestivation. It has a tricarpellary ovary which remains fused so syncarpous . Ovary is superior in this order.
