“…Measurements of the thickness of the epidermis appeared to be useful for distinguishing Philodendron species. The general organisation of mesophyll tissue in vegetative organs has not been investigated in the subgenus Pteromischum (grayuM 1996) and Meconostigma (Mayo 1991). The overall structure of the leaves is described in the subgenus Philodendron by croat (1997).…”

“…The genus, has been initially divided into four subgenera: Euphilodendron, Calostigma, Meconostigma and Sphincterostigma (schott 1832), and later into two subgenera Euphilodendron (=Philodendron) and Meconostigma (engler 1899, krause 1913), is now subdivided into three subgenera. Pteromischum with 75 species (grayuM 1996), Meconostigma with 15 species (Mayo 1988(Mayo , 1991(Mayo , croat 1997 and Philodendron with more than 600 species (croat 1997) are accepted worldwide (Mayo 1988, grayuM 1990, 1996, Mayo et al 1997, croat 1997, sakuragui et al 2005). Two of them, i.e.…”

“…Two of them, i.e. Meconostigma and Philodendron, are morphologically well defined (Mayo 1990(Mayo , 1991. Recently the subgenus Meconostigma has been revised (Mayo 1991(Mayo , gonçalves & salviani 2002 and partial revisions of the subgenera Pteromischum (grayuM 1996) and Philodendron (croat 1997) have been published.…”

aBstract. A comparative morphological and anatomical study on the petioles and lamina of 22 taxa (species, subspecies and cultivars) of the genus Philodendron (subgenera Meconostigma, Pteromischum and Philodendron) has been made in order to investigate interspecific differences which may be useful in species identification. All species have bifacial leaves with petioles, amphistomatic with a strongly reduced density of stomata on the adaxial leaf surface. The species differ in the size and shape of their epidermal cells, the distribution and types of stomata and cuticle ornamentation in the lamina, thickness of epicuticular layer, presence or absence of hypodermis, structure of spongy mesophyll, thickness of palisade and spongy mesophyll layers, as well as types of raphides, and in the structure and forms of petioles. A combination of these characters may be useful in species identification. This study shows that there is some variation in petiole and leaf morphological and anatomical characters among the 22 taxa of Philodendron. However, many characters are present in all of them and may be typical of the genus. The study revealed several detailed interesting epidermal and anatomical features that have not previously been reported in the genus.
