A) Poaceae
B) Asteraceae
C) Brassicaceae
D) Papilionaceae
Correct Answer: B
Solution :
Flowers of members of Asteraceae are small, sessile, bracteate (bract scanous, deciduous or persistent) or ebracteate, tubular or ligulate, complete or incomplete, perfect unisexual or neuter, epigynous, pentamerous in some whorls, cyclic- Tubular or disc florets-regular, actinomorphic, tubular. Ligulate or ray florets-irregular, zygomorphic, ligulate. Flowers of members of Poaceae (Graminae) are small, sessile, surrounded by 2 scales lemma (inferior or outer palea) and palea (superior or inner palea). The lemma is considered to represent a bract while a palea is formed by fusion of 2 bracteoles. Lemma may bear a long stiff process called awn or arista, which is continuation of its midrib, irregular, zygomorphic, incomplete perfect or unisexual (eg, maize) hypogynous. Flowers of members of Brassicaceae (Cruciferae) are ebracteate or rarely bracteate (eg, Rorippa montand), pedicellate, complete, perfect, regular, actinomorphic, rarely zygomorphic (eg, Iberis, Teesdalid), tetramerous or bimerous, hypogynous (perigynous in lepidium), cyclic, cruciform. Flowers of members of Papilionaceae (Fabaceae) are bracteate or ebracteate, rarely bracteolate (eg, Arachis), pedicellate or sessile, complete, perfect, irregular, zygomorphic, papilionaceous, perigynous or occasionally hypogynous.
