-
Family Fabaceae differs from Solanaceae and Liliaceae. With respect to the stamens, pick out the characteristics specific to family Fabaceae but not found in Solanaceae or Liliaceae.

In fabaceae family the filaments of nine stamen are united into one bundle and tenth posterior stamen stand apart (diadelphous condition). Anther in fabaceae is of two lobes or two theca thus called dithecous anther. These two characteristics are present in the members of fabaceae family but not found in members of solanaceae or liliaceae family. Androecium: ten, diadelphous, anther dithecous
