Memoranda Societatis pro Fauna et Flora Fennica sv-FI (Henry Väre) (Jani Laatikainen) ma, 08 maalis 2021 00:00:00 +0200 OJS 60 Reproduction range of garfish, Belone belone (L.), in the northern Baltic Sea <p>The garfish (<em>Belone belone</em> (L.)) annually migrates from the North Sea to the Baltic Proper. Before this study, the known reproduction areas were located in the southern Baltic Sea up to the Islands of Gotland, Saaremaa and Hiiumaa. However, the larvae collected with a beach seine in 2005 and further observations of 0+ larvae and juveniles after that indicated successful reproduction in the northern Gulf of Finland and the southern Gulf of Bothnia. These catches of 0+ garfish and several other observations of garfish larvae and juveniles during recent decades demonstrate that today the species is annually also reproducing in the northern Baltic Sea. The salinity limit for garfish reproduction is not precisely known; however, the lowest reported value 5-6 ‰ fits well with our observations. We recorded garfish larvae along shallow sandy shores where the temperature is higher than in adjacent open water areas. We suggest that the longterm increase of surface water temperatures in the Baltic Sea have enabled the reported expansion of garfish reproduction range.</p> Lari Veneranta, Lauri Urho Copyright (c) 2021 Memoranda Societatis pro Fauna et Flora Fennica ma, 08 maalis 2021 00:00:00 +0200 Mårten Magnus Wilhelm Brenner, Finnish plant enthusiast <p>Mårten Magnus Wilhelm Brenner (1843–1930) was a controversial figure in Finnish botany. He was a passionate non-professional botanist, amongst the most diligent Finnish writers of his time having published 220 articles or notes. He described 833 taxa, including 411 species, six subspecies, 196 varieties, four subvarieties, 199 forms and 17 subforms. Typifications of 151 names are provided in a separate article.</p> <p>Brenner was particularly interested in the <em>Hieracium</em> taxonomy, but he studied several other plant genera and species during almost 60 years of botanical activity: <em>Alnus, Erophila</em> [<em>Draba</em>] <em>verna, Euphrasia, Juncus, Linnaea borealis, Picea abies, Pimpinella saxifraga, Primula officinalis</em> [<em>veris</em>], <em>Rosa, Sorbus aucuparia, Taraxacum</em> and <em>Viola tricolor</em>, for example. His descriptions resulted largely from his own collection activity without any synoptic work. Typically, each taxon was based on small, minor details, sometimes on a single or a few specimens, and often characterised by local distribution. Producing detailed infraspecific classifications was common practice in those times, apparently inspired by the German school of taxonomy, which was later called the Aschersonian approach.</p> <p>For many obvious reasons, botanists of that and later eras did not appreciate Brenner’s taxonomic results. Only some <em>Euphrasia</em> (one taxa), <em>Hieracium</em> (11) and <em>Taraxacum</em> (20) names are currently accepted in the Checklist of Finnish vascular plants, and<em> E. wettstenii</em> var. <em>botniensium</em> has recently been recognised. Brenner’s interest was not restricted to vascular plants. He collected an amount of lichens in late 1869 and 1870 on the island of Suursaari in the Gulf of Finland, for example, and he published extensive floristic accounts of Suursaari and northern Finland. He focused also on ecology and was concerned about changes in nature resulting from human activity. In northern Finland he collected bryophytes, many of which were new to Northern Ostrobothnia. He wrote a review of the history of lichenology in Finland, which the editorial board considered supercritical and did not accept, and which he therefore released as a self-published edition.</p> <p>Brenner became a member of the <em>Societas pro Fauna et Flora Fennica</em> in 1863, holding the position of Secretary in 1866–1876, and he was a member of the Printing Committee for the Publication Series in 1873–1878, 1884–1888 and 1890–1894. However, he was disliked because of his arrogant and presumptuous character, and he sometimes referred to the findings of others as his own at the monthly meetings of the Societas. Eventually, in 1890, he drifted into a polemical relationship with researchers working at the Botanical Museum. His extensive private herbarium was donated posthumously to the Botanical Museum, nowadays the Botanical Museum (H), Finnish Museum of Natural History (Luomus), University of Helsinki, and, he had already donated several batches of plant specimens he collected on trips funded by the Society. <em>Carex brenneri</em> Christ. is lectotypified here.</p> Henry Väre Copyright (c) 2021 Memoranda Societatis pro Fauna et Flora Fennica ti, 09 maalis 2021 00:00:00 +0200 Personalities of Russian amateur botany, 3. Ivan M. Schvetzov and Theodor S. Nenukow, prominent experts in the flora of Nizhni Novgorod Region, and the taxonomic identity of plant species described by Nenukow <p>Ivan Schvetzov collected many specimens of vascular plants, fungi, mosses and lichens mostly from the western part of Nizhni Novgorod Region of Russia, including the original collections of <em>Cytisus ruthenicus</em> var. <em>zingeri</em> Nenukow. Theodor Nenukow was a prominent amateur botanist from Nizhni Novgorod. He studied the flora of Nizhni Novgorod Region, weed and meadow flora of Central Russia and vascular plants of Estonia. He described a few infraspecific taxa and two species of vascular plants, <em>Valeriana estonica</em> Nenukow (synonymised here with<em> V. officinalis</em> subsp. <em>tenuifolia</em> (Vahl) Schübl. &amp; G.Martens) and <em>Odontites estonicus</em> Nenukow (a synonym of <em>O. vulgaris</em> Moench), and the basionym for <em>Cytisus zingeri</em> (Nenukow) V.I.Krecz. (a glabrous variety of <em>C. ruthenicus</em> Fisch. ex Otto). The places of valid publication are clarified for<em> C. ruthenicus</em> var. <em>zingeri</em> and <em>Persicaria linicola</em>, and the lectotype is designated for<em> C. ruthenicus</em> var. <em>zingeri</em>.</p> Alexander N.
