Caucasia, N. Iran. Recent exploration has shown that this is quite a widespread species in easternmost Turkey. It is certainly very closely related to O. tourne-fortii and only clearly distinguished from it by the longer teeth on the crest of the fruit. O. radiata, O. tournefortii, O. hypargyrea, O. cappadocica and O. nitida together form a group of very closely related species. When their range of variation is better known, it is possible that some of them should be accorded subspecific status.
An anomalous gathering which may be referable to O. radiata is C9 Mardin: 7-10 km from Cizre to Silopi, 400 m, D. 42725! In habit, leaves, inflorescence and floral characters it comes within the variation range of O. radiata, but in fruit it is clearly different. The fruits are c. 20 x 15 mm, soft-textured, unarmed and with an arachnoid-velutinous indumentum; they are, however, rather immature and the ripe fruits may be more typical. D. 42725 may represent a new and interesting taxon, but more material is needed.
