MORPHOLOGICAL AND MICROMORPHOLOGICAL STUDIES OF NONEA (BORAGINACEAE: TRlBE BORAGINEAE) IN IRAN

Nonea Medik. is one of the major genera of Boraginaceae tribe Boragineae, with approximately 35 species in the world. In this study we focused on reproductive characters, which are not generally affected by environment. Our seJected reproductive characters have been the stigma form, position of stigma towards the anthers, form of faucal scales, color, form and symmetry of flowers and characters of rnericarps, An identification key using morphological and micromorphological characters has also been proposed. In the present paper above mentioned characte rs have been described for the first time in N. turcomanica M. Pop, N. lutea (Desr.) DC. var. flave scens Lipsky, N. perSICO Boiss. var. suchtelenioides (Riedl) Falatoury & Pakravan, N. diffusa Boiss. et Buhse, N. rosea (Bieb.) Link and N. melanocarpa Boiss. Nonea suchtelenioides H. Riedl has been decreased to the variety level of Nonea persica as N. persica Boiss, var. suchtelen ioide s (Riedl) Falatoury & Pakravan
