CALYMPERACEAE SPECIMENS COLLECTED BY MAX FLEISCHER IN THE “MUSCI FRONDOSI ARCHIPELAGI INDICI ET POLYNESIACI EXSICCATI” SERIES AND PRESERVED AS FRAGMENTS IN THE EGR HERBARIUM (EGER, HUNGARY)

Absztrakt

Twenty-one small moss fragments belonging to taxa in the Calymperaceae were discovered in the Herbarium EGR (Eger, Hungary). These specimens originate from Max Fleischer’s exsiccata series Musci frondosi Archipelagi Indici et Polynesiaci exsiccati (1900–1908), one of the most significant early bryological collections from the Indo-Pacific region. Although fragmentary, this material provides valuable insight into the history of early tropical bryological collecting and exsiccatae distribution. In addition to the EGR remnants, Fleischer’s exsiccatae are preserved in several major herbaria worldwide including FH, E, BM, G, L, NY, PC, U, W providing essential comparative context for reconstructing the provenance, circulation and broader historical trajectory of these collections. Each fragment from EGR was examined and re-identified according to current taxonomic concepts, but the principal contribution of this study lies in documenting the presence of these rare Indo-Pacific exsiccatae in a Central European herbarium and demonstrating their relevance for historical biogeography, specimen exchange networks and the reconstruction of Fleischer’s collecting legacy. Updated identifications and specimen data are provided to support future historical and curatorial research.
