Sobre el género Sternbergia (Amaryllidaceae) en Iraq

Abstract

Sternbergia is a genus containing mostly remarkable autum flowering taxa within Amaryllidaceae. Its distribution ranges from the Mediterranean region through the Irano-Anatolian region to Caucasus and Central Asia. In Flora of Iraq, the information about the occurrence, habitat, and distribution of its species is outdated or incomplete. The main aim of this study has been to contribute with new data from the field in order to update its status in the Kurdistan Region. Botanical field surveys were mostly carried out between 2013 and 2015 in autumn and spring. The main result of this study has been the occurrence of 3 species of Sternbergia: S. colchiciflora, which is reported in this study for the first time for the Kurdistan Region and therefore for Iraq; S. clusiana, which has been rediscovered in Iraq; and S. vernalis, which has been found again in the Berwarya Mountains, after being considered a lost species in Iraq over the last 80 years. These 3 observed species occur in the mountains of Amadiya District, making this area the richest territory for Sternbergia in the country. Due to certain factors that currently threaten their natural habitats, they are rare species and could be regarded as potentially endangered at regional level according to the IUCN criteria.
