Question

Indefinite number of stamens are characteristic of the family

• A. Musaceae
• B. Apocynaceae
• C. Malvaceae
• D. Asteraceae

Answer 1

The correct option is C Malvaceae

Indefinite number of stamens are characteristic of the family Malvaceae. The characteristic feature of family Malvaceae is monadelphous androecium. The flowers of Malvaceae are commonly borne in definite or indefinite axillary inflorescences, which are often reduced to a single flower, but may also be cauliflorous, oppositifolious or terminal. They often bear supernumerary bracts. They can be unisexual or bisexual and are generally actinomorphic, often associated with conspicuous bracts, forming an epicalyx. They generally have five valvate sepals, most frequently basally connate with five imbricate petals. The stamens are five to numerous and connate at least at their bases but often forming a tube around the pistils. The pistils are composed of two to many connate carpels. The ovary is superior, with axial placentation, with capitate or lobed stigma. The flowers have nectaries made of many tightly packed glandular hairs, usually positioned on the sepals.
Therefore, the correct answer is option C.
