Botanical literature was significantly enriched by an outstanding volume printed in 2021. We welcomed the publication of the nearly 8-decade-old manuscript of the famous botanist Erazmus Iulius Nyárády (original title in Hungarian: Szovátafürdő és környékének monográfiája), which deals with the geography, flora and vegetation of Sovata Baths, based on field surveys in the period 1943-44.

Taxonomic status and nomenclature of Tanacetum clusii (Asteraceae, Asteroideae, Anthemideae), with comments on its distribution

The paper provides nomenclatural and taxonomic accounts on Tanacetum clusii, a diploid species found in the Eastern Alps, the Carpathians, and the Dinarides, as well as comments on its current distribution. A careful examination of historic taxonomic literature showed that the combination T. clusii was first proposed by Kerner and predates a currently used much younger isonym by Soják (1871 vs. 1971). One specimen, a karyovoucher from WU, is designated here as an epitype for the illegitimate name Pyrethrum clusii, upon which Chrysanthemum clusii, the basionym of T. clusii, is based. This designation aims to avoid ambiguity in the taxonomic interpretation of its previously selected lectotype. Based on examining the original material, a voucher from SIB is designated as a lectotype of the synonymic name Chrysanthemum subcorymbosum, a basionym of Tanacetum corymbosum subsp. subcorymbosum. The last name is the only correct one in the rank of subspecies when T. clusii is alternatively treated as a separate subspecies within T. corymbosum s.l. In addition, one specimen from SAMU is designated here as a neotype of Pyrethrum corymbosum f. macrocephalum, a newly discovered heterotypic synonym of T. clusii. The analysis of the current species distribution showed that T. clusii is native to Switzerland (confirmed!), Italy, Austria, Slovenia, Croatia, Bosnia and Herzegovina, Hungary (confirmed!), Slovakia, Poland, Ukraine, and Romania. Although currently not accepted for Switzerland in literature, T. clusii could be confirmed for the Swiss canton of the Grisons. The same applies for Hungary where, apart from the Bükk Mts in literature, new localities from the Kőszeg and Mátra Mts are presented here. Additionally, the presence of T. clusii in Bulgaria, the Czech Republic, France, Greece, Montenegro and Turkey has not been confirmed and recorded mistakenly in different sources

Performance in the recruitment life stage and its potential contribution to invasive success in the polyploid invader Centaurea stoebe /

The recruitment life stage, including germination and early seedling establishment, is the most vulnerable life stage of plants and has cascading effects on plant performance at later life stages. However, surprisingly little is known on the eco-evolutionary processes that determine the success of biological invasions at this life stage. We performed germination experiments with and without simulated drought stress and monitored early seedling growth in diploid and tetraploid Centaurea stoebe. While diploids are the major cytotype in the native European range, only tetraploids became invasive in North America. Thus, C. stoebe is an excellent model species to simultaneously study both, pre-adaptive differences in the native range (diploids vs. tetraploids) and post-introduction evolution in the non-native range (native tetraploids vs. non-native tetraploids). To account for broad spatial-environmental variation within cytotypes and ranges, we germinated 23, 928 seeds from 208 widely distributed populations. Tetraploids germinated better than diploids. Within tetraploids, invasive populations outperformed native populations in germination. However, these differences were not evident under simulated drought stress. Seedlings of invasive tetraploids had a higher biomass and developed the first true leaf earlier than those from the native range, while the native cytotypes did not differ in these early seedling traits. Our results suggest that a combination of pre-adaptation related to superior performance of polyploids (greater and faster germination) and post-introduction evolution towards higher performance in the invasive range (greater and faster germination, greater and faster accumulation of seedling biomass) may have contributed to the invasion success of tetraploid C. stoebe in North America
