Species of Apiaceae despite uniform floral structure show great variation in floral morphs and sexual distribution. In the present study, ontogeny of the diclinous flowers within “cage-like” inflorescence of the andromonoecious Dicyclophora persica Boiss., studied using scanning electron microscopy (SEM), in order to recognize whether they follow the same ontogenetic processes. The development of interesting unusual club-like organ in center of the umbel, furthermore, studied. The floral organs in diclinous flowers initiated from the common sectorial group-like primordia. Petals initiated as clockwise direction and stamens as modified helical pattern. Perfect flowers, despite sepal suppression, synchronized with staminate flowers in initiation of petals, stamens and carpels. In staminate flowers, in turn, two prominent sepals arise subsequently after initiation of stamens. Only in late stages, ovules get aborted. The club-like organ initiated from a naked receptacle that has no resemblances to the umbellets or flowers. The prolonged spatial constrains imposed by massive staminate flowers are responsible for suppression of sepals and sessile status of perfect flowers. Considering the ovules suppression, staminate flowers may likely adopt to conserve the perfect flowers from exposing in extreme environmental conditions, but not as substitution for perfect flowers.

A new species of Gagea iranshahrii ***** & ***** (Liliaceae, G. sect. Stipitatae (Pascher) Davlianidze) has been described from the basin of the Atrak River basin, Iran and Turkmenistan. Morphological features and a distribution map are given. Differences from four superficially similar taxa are indicated. The new species differs in the totality of features and, especially, in the presence of a relatively large, rounded vegetative bulb, which forms annually throughout the entire ontogenesis.
