Abstract

Šegota, V. Vilović, T. & Zovko, I.: Orchid (Orchidaceae) diversity within Herbarium Croaticum (ZA) collection sensu stricto. Nat. Croat., Vol. 28, No. 2, 325-343, 2019, Zagreb. The collection of orchids within Herbarium Croaticum sensu stricto keeps as many as 1373 herbarium sheets, belonging to 91 taxa (25 genera, 76 species, 11 subspecies and four hybrids). The majority of the collection originates from Croatia while the rest are from neighbouring countries (Slovenia, Serbia, Bosnia & Herzegovina, Italy, North Macedonia and Montenegro). The most numerous genera are Orchis, Ophrys and Anacamptis, while the most numerous taxa are Gymnadenia conopsea, Platanthera bifolia, Anacamptis morio, Neotinea tridentata, Cephalanthera longifolia and Dactylorhiza maculata. The oldest herbarium sheets date back to 1883 and the average age of the collection is 113 years. The main collectors are Ljudevit Rossi, Dragutin Hirc and Ambroz Haračić. The collection keeps holotypes and isotypes of Epipactis rivularis and Ophrys dinarica, while exsiccates of Malaxis monophyllos, Herminium monorchis and Ophrys × muellneri are the only evidence of their existence in Croatia. All sheets were digitized and are publically available via virtual herbarium.
