Lamium ponticum Miller

Type :— TURKEY. A8 RIZE. in Ponto Lazico maritimo circa Rhize, vi 1866, Balansa 892 (holotype G!) .

The corolla of Lamium ponticum is quite different from L. moschatum subsp. moschatum and L. moschatum subsp. micranthum . The lateral lobes of the lower lip of the corolla of L. ponticum are filiform, while L. moschatum subsp. micranthum has oblong and clearly thicker lobes. There is a clear pink dot just below lateral lobes of lower lip of corolla in L. ponticum , while the corolla of L. moschatum subsp. micranthum is completely white, with no pink dot on the corolla. Pollen grains are orange color in L. ponticum , while pollen grains of L. moschatum subsp. micranthum are yellow. The inflorescence is pilose hairy in L. ponticum , while the inflorescence is glabrous or subglabrous in L. moschatum subsp. micranthum . Unpublished molecular results (Celep et al. in prep.) also shows that L. moschatum and L. ponticum are different species. Therefore, based on all evidence we resurrected L. ponticum in this paper.
