Abstract

Lotus sanguineus is one of the endemic taxa from Mediterranean Region of Turkey. It has hitherto been known from type locality and was assessed under VU and EN categories despite the lack of information on the population size, number of location and habitat quality. This study aims to determine the global conservation status and conservation strategies of the narrow endemic species. We collected all available data and evaluated them with the field studies. We reported the sizes of populations, altitude, coordinates, habitat types and the threats it faces for each locality. GeoCAT analyses at global levels indicate the extent of occurrence 19.965 km2 and area of occupancy 9 km2 and there could be an inferred decline due to habitat loss and fragmentation of the original population, suggesting this species might be classified as Critically Endangered, based on criterium B1ab (i, ii, iii) + 2ab (i, ii, iii) in the Red List categorization. Conservation priorities include life history and ecology studies, in-situ conservation, population monitoring and ex-situ conservation to prevent the destruction of the existing gene pool.

Abstract

This study evaluates Ornithogalum brevipedicellatum, which was previously accepted as a synonym of O. oligophyllum, as a separate distinct species and discusses the similarities and differences between O. brevipedicellatum and its related species (O. oligophyllum and O. pamphylicum). Similarities and differences among these species were identifi ed by morphological and molecular studies. The leaf morphology and inflorescence of O. brevipedicellatum and O. pamphylicum are similar to each other, and in terms of these features, they show differences from O. oligophyllum. Some diagnostic characteristics are quite different in O. brevipedicellatum and O. pamphylicum, such as the size of tepals, length of fruiting pedicels and style. Morphological data were supported by the results obtained from molecular studies. According to a dendrogram obtained by molecular studies, O. brevipedicellatum and O. pamphylicum are similar. O. oligophyllum is more closely related to O. pyrenaicum used as an out-group. Additionally, the seeds of O. brevipedicellatum were examined with the use of scanning electron microscopy
