In recent years, as part of various projects to digitize herbarium collections, botanists have been reaching forgotten or considered lost collections. During the digitization of herbarium collections stored at the Jagiellonian University Herbarium carried out as part of the IMBIO project under the direction of Prof. Marcin Nobis, we reviewed more than 650 herbarium sheets with plant specimens collected by the famous Polish botanist, patron of the horticultural school complex in Pomology near Poland, Józef Warszewicz. These collections come from his travels to Central and South America. In this paper we present a typification of five species names described on the basis of J. Warszewicz's plant material. Among other things, we have indicated the lectotypes for the Berberis warszewiczii, Esenbeckia warscewiczii, Psammisia ramiflora, Remijia involucrata i Rondeletia orthoneura, and we also reported the presence of 17 specimens (isotypes) representing the Esenbeckia cornuta, an extremely rare species that is so far known only from one typical site in Peru. We also presented a list of all specimens collected by J. Warszewicz preserved in the KRA herbarium.

Abstract

Jozef Warszewicz (1812-1864) was one of the first Polish naturalists to explore the flora of the tropical New World. During two expeditions to Central and South America (1844-1850 and 1850-1853) he collected and delivered to Europe up to twenty thousand plant specimens. To honor his service and his achievements in plant collections, different taxonomists described more than 100 taxa using the surname Warszewicz, for example in the genus name (Warszewiczia) and the species epithets (warszewiczii, warscewiczii, warszewicziana). Unfortunately, a large part of Warszewicz's collection of plant species deposited in the Berlin Herbarium (B), including many type specimens was destroyed during World War II. During digitization of herbarium collections preserved in the Herbarium of the Jagiellonian University (KRA), we reviewed more than 650 herbarium sheets with plant specimens collected by Warszewicz and originating from his trips to Central and South America. In this paper, we present the typification of five names of species, described base on Warszewicz's plant material. We select lectotypes for Berberis warszewiczii, Esenbeckia warscewiczii, Psammisia ramiflora, Remijia involucrata and Rondeletia orthoneura, and provide data on the presence of 17 specimens (isotypes) representing Esenbeckia cornuta, an extremely rare species, that to date is known only from the type locality in Peru. A list of all Warszewicz's specimens preserved at KRA herbarium is also presented. Additionally, in the result of the revision of syntypes of Brerberis multiflora and Rondeletia reflexa we designated here the lectotypes for these taxa.
