Seeds of ten species of Hibiscus L. were collected from different locations within South Western Nigeria and the crude proteins were extracted and analysed by electrophoretic fractionation. The species of the genus have one common band. Interspecific bands varying from eight to nine are common between pairs of species. These show the close genetic relationship of the species. The number and combination of protein bands were taxon-specific.
Pollen grains of ten species of Hibiscus Linn. Were collected from different locations within South Western Nigerian and acetolysed. The various sizes, length of spines, distance between spines, diameter of apertures, distance between apertures and nature of spine end are useful tools in the taxonomy of the Hibiscus species studied.
