An anther with two microsporangia is found in:
1 Solanaceae
2 Fabaceae
3 Malvaceae
4 Liliaceae
Explanation:
Generally, the anther consists of two lobes separated by a longitudinal groove. Each lobe is often called as theca and each theca has two microsporangia also known as pollen sacs. e.g., in Hibiscus family Malvaceae, the anthers are monothecous.
