A comprehensive anatomical study of the nodes and leaves of 21 species in five genera of Staphyleaceae was conducted to clarify the systematics and major trends of specialization and radiation within the family. The fundamenta staphyleaceous nodal pattern is trilacunar, three-trace, although a considerable range of variation exists within genera in numbers of traces and gaps and in the nature Cited by: Apostasiads, systematic anatomy, and the origins of Orchidaceae Research was carried out in the hope of providing objective information from anatomy towards unravelling the relationships of these plants, and especially towards answering the question of whether extant orchids evolved from these two genera, or from plants like them.
The specialized leaf anatomy for species of Dendrobium within section Aporum is similar to that of species in section Rhizobium. In both sections leaves are characterized by a unifacial or nearly unifacial surface where the exposed surface is abaxial. However, leaves in section Rhizobium also feature a lacuna submerged in the mesophyll and surrounded by an adaxial astonmartingo.com by: A critical revision of certain taxonomic groups of the Malvales, New Phytol. and Ellis, R.P.

The leaf anatomy of species of New World Velloziaceae has been studied with the purpose of providing important character-states in assessing the systematics of the family. Transverse section of the leaves have shown the type of sclerenchyma and mesophyll patterns that are assignable either to the genus Vellozia or Barbacenia (sensu lato).
