| Description | The only record known of the halophilous species Aster canus from the today's territory of the Czech Republic was published by Christian Ferdinand Hochstetter, 1817-1824 serving as Lutheran minister in Brno, in the botanical journal Flora (Regensburg) in 1825. The species was reported to grow in a small wood adjacent to the former Měnín Lake near the village of Měnín (Mönitz) southeast of Brno. The lake with saline water was drained shortly afterwards. Since then, the occurrence of A. canus has never been confirmed though it was repeatedly searched for by Moravian 19th-century botanists, e. g., A. Makowsky, and no herbarium specimen has been known. The species has been considered vanished but some doubts still existed about its former presence. Recently, another two literature reports, both written and published by Hochstetter in 1823, were found, containing information on a less known exsiccate series, Gewächse des Brünner Kreises, consisting probably of 500 species, further a list of species of the Moravian flora and also records of A. canus. A subsequent search in the herbarium WU-Keck, renown for very old herbarium specimens and original material, yielded a specimen of A. canus collected by Ch. F. Hochstetter near Měnín in 1824 or somewhat earlier, confirming its indigenous status in the Moravian flora. |
