Most representatives of the third largest angiosperm family, Leguminosae, share
monosymmetric flowers with a precisely defined number and morphology of all parts
especially the corolla. However, in some lineages monosymmetry is lost. This alteration is
usually associated with an increase of variation in number of floral organs. This paper
reports the results of a survey on floral ontogeny in African basal papilionoid legume
Cordyla pinnata. The flowers of this tree are polysymmetric (except for the carpel, if single) …
