Hyoscyamus tenuicaulis Schonbeck-Temesy is a flowering species of the Solanaceae family and it is endemic to Iran, growing in scattered spots and hanging in the crevices of rocks, cliffs, and vertical walls of rivers. It is a perennial and rhizomatous plant with creeping or fully hanging stems up to 2 m long. The conservation status of the species was defined based on IUCN Red List Criteria and Categories. According to the field survey and plot sampling, H. tenuicaulis occupies an area of 22.4 Km2, and the extent of occurrence is 159507 Km2. Based on the area of occupancy (AOO), population size, regeneration type, and the quality of habitats, the conservation status of this species is defined as endangered (EN). Field observations have shown that the lack of proper management and overexploitation as a medicinal plant are the main threats to this rare species. Defining protected habitats by Forests, Rangelands, and Watershed Management Organization (FRWO), ex-situ conservation in the National Botanical Garden of Iran, Zagros Botanical Garden, and natural resources gene bank are suggested to be considered for conservation of this species.
