| Description | A specimen of Dracocephalum parviflorum collected by the Bohemian German-speaking hobby botanist Robert Wihan in 1928 in the town of Pec pod Sněžkou in the Krkonoše Mts in north-eastern Bohemia was found in the herbarium of the National Museum in Prague. The plant was found near an abandoned furnace used in the 19th century for the production of arsenic trioxide but no information is given on the herbarium label about a possible way of introduction. The herbarium specimen, originally identifi ed as Galeopsis ladanum, arrived in the National Museum together with the herbarium of Robert and Jenny Wihan in 1946 and remained there unrecognised until recently. This is the fi rst and only record of this Dracocephalum species, native to North America, in the Czech Republic. Consequently, D. parvifl orum has to be considered as a casual neophyte of the Czech fl ora, which is also the case in several other countries of Europe. |
