Andrea B. Posted May 20, 2013 Share Posted May 20, 2013 Blum, A.G. (2017) Veronica persica Poiret (Plantaginaceae) Persian Speedwell. Flowers photographed in ultraviolet and visible light. http://www.ultraviol...sian-speedwell/Updated 15 April 2017A visible photograph of a V. polita raceme, mistakenly posted here, was removed and placed into the Veronica polita post. SynonymsPocilla persica (Poir.) Fourr.Other Common NamesBird's-eye SpeedwellCommentA pretty little sky-blue zygomorphic weed which typically has a UV-dark center including the stigma and two stamens. Classification of the Veronicas into groups based on their iridoid glucosides and chromosome numbers shows that the very closely related V. polita and V. persica both belong to group II.(2) Practically, the difference between the two species in the field can be determined by measuring the corolla width and pedicel length.V. persica :: corolla 8-11mm wide and stalk 15-40mm longV. polita :: corolla 4-8mm wide and stalk 6-15mm long Reference:1.
