The keystone of modern Slovenian floristics is the herbarium collection Carniolan Dried Flora (Flora exsiccata Carniolica), gathered and edited by the botanist Alfonz Paulin (1853-1942), a leading scientist in botany at the turn of the 19th century. His work was highly versatile, for he wrote the first original botanical textbook in the Slovenian language and managed the Garden of Homeland Flora in Ljubljana from 1886 to 1931. He was active in the endeavours to preserve the natural heritage and collected the bulk of material for the Critical Flora of Carniola which, unfortunately, he did not also write. The dried flora of Carniola was continually published over a long period of 35 years (1901-1936) and remains uncompleted. 2,000 sheets were published, 10 before World War I and 10 after it. The herbarium sheets were printed for the first 1,000 specimens and were published in five special volumes, their author being Alfonz Paulin. The most comprehensive reports were published for the first 6 centuries, where we find, apart from precise data on the habitat in which the plant was collected, data on its distribution in Carniola. In the next four centuries, the labels were printed but only contained the usual information on the plant’s locality. The last thousand labels are handwritten. Their text was translated from Latin and published by Paulin’s colleague Fran Dolšak (1,000 to 1,800). It was not until 1966 that Tone Wraber published a list of the last two centuries.
