Helianthemum antitauricum P.H.Davis & Coode, a member of the Cistaceae family, is a narrowly distributed and endemic species. A new distribution site for the species Helianthemum antitauricum has been identified in Mürsel neighborhood of Göksun district in Kahramanmaraş. This study introduces the newly discovered population of the species. Helianthemum antitauricum grows on limestone substrates and coexists with high-mountain steppe plants, some of which are also endemic. The species demonstrates an adaptive capacity to slightly alkaline, non-saline, and nutrient-poor soil conditions, preferring loamy sand soils and areas with high surface rockiness. It occurs at an average altitude of 1952 m, primarily on shaded slopes. The conservation of this species, whose presence is limited and threatened, is crucial both within and outside its natural range, and immediate measures are necessary to ensure its survival. Individuals produced in nurseries can be used as a pioneer species in erosion control projects. Additionally, Helianthemum antitauricum, adapted to nutrient-poor soils with high surface rockiness, can be utilized in rock garden and stone garden designs. Considering its altitude range, the species is likely resistant to cold and frost, making it suitable for use in high-altitude gardens as well. In addition, the capacity of Helianthemum antitauricum to provide pollen and nectar for apiculture should be determined.
