TURKEY-in-EUROPE: Istanbul, Silivri, Sinekli, Delice & Bulut (LD, ISTF 30535). Characterized by small, few-flowered, usually hemispherical clusters, papillose peduncles and relatively short seed appendages. Plants from E Bulgaria and the Sofia vicinity are ±variable in the diagnostic characters, perhaps due to hybridization. In the S Pirin Mtns, introgression with L. campestris subsp. campestris was observed (J.Kirschner, Preslia 63: 81–112, 1991). The distribution is imperfectly known. 101
