Abstract

Micromorphological attributes for five species of C. gynandra L., C. viscosa L, C. scaposa DC, C. paradoxa B.BR and C. brachycarpa Vahl ex DC. belonging to genus Cleome L. in south west of Saudi Arabia was studied by light (LM) and scanning electron microscope (SEM). Studies are interested by hair characters, stomata behaviour, stem and leaf anatomy, pollen grains and seed exomorphic attributes. Stem and leaf anatomy differentiation indicated good taxonomic tools to between species the species, the result of the stomata frequency was significant where the highest stomatal index (SI) of 36.4% was observed in C. gynandra while the lowest one (21.6%) was noticed in C. Paradoxa. However, pollen grains and seed exomorphic is significantly helpful at the specific level. Prolate, tricolpate, monad pollen grains are found in all studied species pollen grains differed in P/E (polar axis / equatorial axis) ratio and exine measurements. Also, every Cleome species has their own seed ornamentation which will be helpful information in differentiation of the studied species. On the basis of seed ultrastructure, three main types of seed ornamentation; reticulate, verrucate and oceallate were revealed. Analysed data by Minitab (Version 13.1) statistical program showed C. gynandra in single level while the remainders were grouped in one cluster in which C. viscocs and C. scaposa are excluded in a alone separated levels in addition the highest similarity percentage appered between C. paradoxa and C. brachycarpa.
