The cyclamen (Myrsinascea) as the flowers growing in some temperate regions, are of high ecological and botanical importance and endangered as well. Therefore, to provide an opportunity to identify and protect its species, Iranian native cyclamen was studied. Plants were collected (in winter and spring) from three northern provinces of Iran, i.e., Guilan, Mazandaran, and Golestan, and their morphological traits (14 quantitative and 10 qualitative traits) were assessed. Based on the analysis of variance, there were significant differences in some recorded traits, e.g., leaf number, flower number, flower color, and flower and leaf shape, which would allow selecting plants with more optimal traits. The cluster analysis divided the plants into three groups. Accordingly, the plants collected from the Shadan region in Golestan province and those collected from the Sinava and Shahsheshmeh regions in Chalus County, Mazandaran province differed from the plants collected from the other regions. The plants were collected from the Abpari and Lavij regions in Nur County, the Pasand region in Behshahr County, the Qarnabad region in Gorgan County, and the Deylaman region in Siahkal County were placed in the same group due to their similar morphology although they had been collected from three different provinces. The first group included the cyclamens of the Qarnabad region in Gorgan County, the Lavij region in Nur County, the Deylaman region in Siahkal County, the Pasand region in Behshahr County, and the Abpari region in Nur County. These plants had lowly toothed leaf margins, long petals, and few seeds. The second group included the cyclamens of the Shadan region in Kordkuy County. These plants had longer and heavier hypocotyls, larger and wider leaves, and smaller flowers. They showed the highest number of seeds, hypocotyl diameter, length, and weight, flower number, leaf length and width, leaf area, petiole and peduncle length, and peduncle diameter. The third group included the cyclamens of the Sinava and Shahsheshmeh regions in Chalus County. They had the highest petal width but the lowest peduncle diameter, leaf length, width, and area, flower and leaf number, and hypocotyl weight, length, and diameter.  The cyclamens native to Iran are highly diverse in morphological traits and they need to be further investigated by cytogenetic, phytochemical, and molecular methods.

Calotropis procera is a small, erect plant, which is used in several traditional medicines to treat many diseases. It is a native of most of the Asian and African countries. All plant parts exude thick white milky juice (latex) on cut or break. This shrub has been known to possess analgesic, antitumor, antihelmintic, antioxidant, hepatoprotective, antidiarrhoeal, anticonvulsant, antimicrobial, oestrogenic, antinociceptive, and antimalarial activity. This article summarized information concerning pharmacognostical aspects of Calotropis procera plant.
