Comparative anatomy and pollen morphology of two endemic Noccaea species (Brassicaceae) and their taxonomic significance

This study was conducted for extensive and systemic investigation of anatomical, palynological seed morphological properties two endemic Noccaea species, naturally growing in Turkey. Independent sample T-test box plot were carried out using quantitative characters the studied species. The anatomical results showed that species had similar characteristics, though there significant differences root cortex cells trachea; stem epidermis, cell endodermis; leaf upper lower cuticle, mesophyll palisade parenchyma. Pollen grains observed as radially symmetric, isopolar, with tricolpate aperture, prolate pollen shape small size. surface ornamentation micro-reticulate both Considering characters, equatorial axis, AMB exine intine have taxonomic importance. Seeds N. birolmutlui ovate to orbicular orange-brown color, colliculate ornamentation; however, seeds camlikensis oblong brown shiny colliculate-reticulate ornamentation.
