Abstract
Floral organogenesis and development of the bushy perennial legume Wisteria sinensis (Millettieae, Fabaceae) were studied by epi-illumination light-microscopy techniques. Zygomorphic flowers of W. sinensis were arranged in alternating pentamerous whorls. The order of organogenesis in each whorl was unidirectional, except for the outer antesepalous stamens, which were initiated bidirectionally, starting on the lateral side. Unusual developmental features for the family included the formation of common primordia, comprised of the petal and the corresponding abaxial antepetalous stamen and the temporal overlap of corolla, androecium and carpel organ initiation. Unusual features during late development included formation of nectar windows and a wet stigma. The floral ontogeny of W. sinensis was more similar to that of other genera from the inverted-repeat-lacking clade (IRLC) than to the floral ontogeny of other Millettieae that have been investigated.
