Systematic significance of stipe anatomy of Pteris L. (Pteridaceae) from Southwestrn Nigeria.

In this study, stipe anatomy of seven Pteris species collected from various locations in the Southwestern Nigeria was investigated. This was with a view to identifying characters of the stipe anatomy that are important in delimiting the species. Transverse sections of stipe at proximal, median and distal regions to the rhizome were cut with the aid of a sledge microtome. The sections were stained in Safranin O, rinsed in three successive changes of water and counterstained with Alcian blue for three minutes. The counterstained sections were rinsed again in water, and then treated in serial grades of alcohol. Observation of prepared slides was made under light microscope. Based on the shape of the vascular bundles, the Pteris species   were in three categories   which are   inverted Omega, V and U shapes. The adaxial grooves varied from proximal to distal regions in all the species except only in P. ensiformis where it was uniform throughout the regions.
