| In this study, palynological, seed and leaflet micromorphological properties of Astragalus victoriae and Astragalus melanophrurius species were investigated in detail using light microscopy (LM) and scanning electron microscopy (SEM). The aim of this study is to determine the contribution of pollen, leaflet and seed morphology characters in distinguishing between these two closely related species. Study results indicate that pollen of species are radial symmetric and isopolar. Aperture type is trizonocolporate. Pollen shape is determined as prolate-spheroidal for Astragalus melanophrurius and subprolate for Astragalus victoriae. Ornamentation type is observed as perforate at polar area and aperture surround, microreticulate at the other sides of pollen for A. melanophrurius while ornamentation determined as rugulate at polar area and aperture surround, microreticulate at the other sides of pollen for Astragalus victoriae. Seeds shape are reniform, the colour is light brown and surface ornamentation determined as psilate in light microscope for both species while reticulate-rugulate with thin and irregular muri determined in Astragalus victoriae and reticulate surface ornamentation with thick and regular muri in Astragalus melanophrurius in SEM micrograph. Leaflet observed as elliptic-ovate, emarginated with dens single celled trichomes on lower surface for A. melanophrurius while narrowly elliptic, apiculate, with densely single-celled trichomes on lower surface leaflet observed for A. victoriae. Trichomes have scabrate ornamentation at A. melanophrurius and striate ornamentation at A. victoriae. On the lower surface of the leaflet of A … |
