The Spathelia-Ptaeroxylon clade is a group of morphologically diverse plants that have been classified together as result molecular phylogenetic studies. currently included in Rutaceae and recognized at subfamilial level (Spathelioideae) despite the fact most its genera traditionally associated with other families there are no obvious morphological synapomorphies for clade. aim present study to construct trees investigate anatomical characters order decide whether it should be kept or familial level. Anatomical were plotted on cladogram help explain character evolution within group. Moreover, relationships generic limits also addressed.
