Cover. Flowers of the narrow standard mutant (left) and a normal flower (right) (see Berdnikov et al., pages 42-43). This mutation also reduces the width of the leaflets and stipules and is possibly allelic with lath. Like lath, the new mutant is completely female sterile. In both mutants the carpel is split open at the dorsal suture with the ovules exposed. In contrast to lath, the new mutant has normal male fertility. It offers several uses. In particular, it may be useful for work in plant development as it adds to the interesting group of mutations that influence both leaf and flower development.
