Background  The present work aimed to verify whether intermediate variants were natural crosses between  Datura  species ( D. stramonium  forms and  D. ferox ). Their existence has been long ago insinuated but has not been studied using morphological features and molecular tools. The variants differed in stem coloring, upper bearing forks, and fruit characters.    Results  Principal Components Analysis of 11 morphological characteristics showed that  D. ferox  and  D. stramonium  (forms  stramonium  and  tatula ) were quite different and the putative hybrids were intermittent. The  D. ferox  ×  D. stramonium  f.  tatula  was closer to the latter of its parents. Sequencing analysis revealed identical amplified trnL intron in all variants and a 100% homology with  D. stramonium  accession number EU580984.1 suggested that this plastid cannot discern  Datura  variants. However, genomic analysis with URP markers indicated that the hybrids had >60% genetic makeup similarity with both parents suggesting that the intermediate variants were putative inter-specific hybrids. Moreover, the dendrogram stemmed from cluster analysis of the fingerprint profile of variants placed  D. stramonium  and  D. ferox  in different branches indicating their genetic differentiation from each other as well as from their hybrids.    Conclusions  The findings suggest that the natural hybridization of annual  Datura  species occurs. Extrapolating, this hybridization could be the first step for speciation. More possibly, it can alter population composition, its weediness and adaptability to local conditions.
