Lectotypification of Two Names in The Family Asteraceae

Aim of study: Within the family Asteraceae, the names Chamaemelum hygrophilum Bornm., which is basionym of Tripleurospermum hygrophilum (Bornm.) Bornm. and Crepis armena DC. were described by Joseph Nicolaus Bornmüller (1862-1948) and Augustin Pyramus de Candolle (1788-1841) from the specimens collected from Türkiye, respectively. In the present study, these names in Asteraceae were typified. Area of study: Yamanlar Mountain (Izmir), Mediterranean and Irano-Turanian regions. Material and method: For the typification of the names Chamaemelum hygrophilum and Crepis armena, protologues of the names, the original materials in B, BM, E, G-BOIS, G-DC, JE, K, LY and P were examined. Main results: The names Chamaemelum hygrophilum and Crepis armena are lectotypified herein on the specimens deposited at JE and G, respectively. Besides, description and distribution pattern of both species are presented. Research highlights: The obtained data can be used for taxonomy of the species T. hygrophilum and C. armena.
