Answer: 1. Four

Count the plants whose flowers have stamens of unequal length.

Salvia: only two stamens, with unequal arms and a lever-like arrangement, so the stamens differ in length from the usual pattern.
Mustard, radish and turnip (Cruciferae): tetradynamous, four long and two short stamens.

That makes four plants. Allium and Aloe (Liliaceae) have six equal stamens, and Indigofera, Sesbania, groundnut and gram (Fabaceae) are counted as diadelphous, not as having unequal lengths, in this question.
