Four Sterculia species (Sterculia alata Roxb., Sterculia diversifolia G. Don, Sterculia platanifolia L.f. and Sterculia foetida L.) grown in Egypt were selected for studying from a pharmacognostical point of view. On the basis of some morphological features, these species were reclassified under different genera and revised as Pterygota alata (Roxb.) R. Br., Brachychiton populneus (Schott & Endl.) R. Br. and Firmiana simplex (L.) W. Wight, respectively. Sterculia foetida L. remained belonging to genus Sterculia. In the present study, genetic, botanical, phytochemical and biological studies were performed in order to find the infrageneric relationships among the four taxa. Genetic analysis through DNA (RAPD-PCR fingerprinting of the fresh leaves) and protein (SDS-PAGE analysis of the seeds) profilings showed great genetic variations between the studied species.
