New data for two rare plant species of Georgian flora
2018
There are more than a few rare and endangered plant species in the flora of Georgia. To find their distribution areas and new populations is vital for their survival and protection. In Autumn, 2017, during the floristic-geobotanical studies in Tbilisi surroundings (East Georgia), two rare species of Georgian Flora were discovered. These species are: 1. Spiranthes spiralis (L.) Chevall (family Orchidaceae) and 2. Sternbergia colchiciflora Waldst. & Kit. (family Amaryllidaceae). One of them, Sternbergia colchiciflora Waldst. & Kit. was included in “Red data book of the Georgian SSR”. Spiranthes spiralis is spread in moist and moderately moist ecosystems, whereas Sternbergia colchiciflora grows in semiarid ecosystems. We located them at the foothills of south-facing macro-slopes of Saguramo ridge. One single population for each of these two species was recorded within the new area. The present paper includes new coordinates of their distribution zones, habitats and associated plants species. Based on given bibliography, older distribution areas are included as well. The paper contains photos of these plants.
