Leave a reply

Abstract
Onosma deltiphylla Attar, Mirtadz. & Sotoodeh and O. humilis Attar, Sotoodeh & Mirtadz. (Boraginaceae) are described as new species from Iran. Morphologically the closest species to O. deltiphylla are O. microcarpa and O. sabalanica, while O. humilis is very distinct due to its very small size, and its closest relative is believed to be O. nana. Morphological traits distinguishing these species from the congeners include the shape of the leaves under the inflorescence and the size of the corolla.
