summary In the temperature‐sensitive ‘stamenless‐2’ ( sl‐2/sl‐2 ) mutant of tomato ( Lycopersicon esculentum L.), normal‐looking stamens are produced under low temperatures, but under high temperature conditions carpelloid stamens develop. Under low temperature conditions, the mutant stamens follow a pattern of development comparable to the normal (+/+) stamens in all respects, e.g. initiation, locule formation and hair production. The ontogeny of carpelloid stamens under high temperature conditions diverged from that of the normal and low temperature‐grown mutant stamens at an early stage of development (<0.2 mm), and followed a sequence of development similar to that of the apocarpous gynoecia of other species.
