The collection of the herbarium was established in 1949, when herbariums of several provincial agronomic academies were fused. The present collection consists of about 42000 specimens of vascular plants . They have been ordered according to the taxonomical system of Engler. The herbarium specimens are classified as genera and species and follow each other in alphabetical order. Beside the collection of vascular plants the collection of cryptogams is notable (fungi, algae, lichens and bryophytes), which consists of 13000 capsules.

    Hereunder we specify some institutes and collectors, whose collections are considerable in the present herbarium. The oldest and probably the most valuable part of the collection is the exsiccatum of József Sadler, ”The Dried Collection of Hungarian Plants, 1823-1825” , which contains plants mainly from Pest county.

    The collection of Gyula Kovács is from the middle of the XIXth century and it was mostly made up by specimen exchanges, but it also contains specimens he collected on his own. The collection of Márton Vrabélyi, which we got from the former College of Eger, contains about 9500 specimens, not just from Hungary, but also from Europe and other parts of the world. Out of his own collection, he collected in the Mátra Mountains, it includes notable material from specimen exchange from the most considerable botanists; he could connect with, as it was a practice of his age. Therefore, it is not surprising that there are many African, Asian and North American specimens , in his collection.

    We also have valuable collections of the following botanists: Vince Borbás, Frigyes Hazslinszky, Viktor Janka, Lajos Simonkai, Zoltán Szabó, Lajos Vágner, Antal Waisbecker, József Budai, Nándor Filarszky and Gyula Gáyer , they contain specimens collected in Hungary. Árpád Degen’s exsiccata, the „Gramina Hungarica” and the „Cyperaceae Hungaricae”, is from the beginning of the 20th century and also have a great value. Arpád Tuzson’s exsiccata, „The collection of the plants of the Hungarian Plain” is an invaluable collection from the whole pretrianonian Hungarian Plain, with data of plants and habitats have totally vanished yet. Herb collections can also be found in the herbarium e.g. Béla Augustin’s exsiccata, „The collection of herbs”. The herbarium contains some of the collections of Sándor Jávorka, who was one of the most remarkable Hungarian botanists of the 20th century. We also have to mention the collections of Károly Lyka, Géza Lengyel, Károly Schilberszky, Gyula E. Nyárády, Lajos Thaisz and Zoltán Zsák. These botanists collected the flora of smaller areas mainly and their specimens characterise the sites, they scoured very well.

    The collections, originated after 1945, are smaller, because collecting and floristical surveys were extinguished. From the time after the Second World War we have to memorate the following collectors: József Jeanplong, Albert Koltay, Imre Máthé, József Papp, Szaniszló Priszter and Sándor Tóth. The herbarium collection is still growing mainly with the collections of the employees of our Department, these specimens are usually collected during Hungarian and foreign expeditions. Our herbarium is one of the most valuable collections in Hungary . The plants are mostly in a good condition and are sticked up. The herbarium specimens are perfect for identifying the species and have an inestimable scientific and historical value.
