Epilobium pseudorubescens A. K. Skvortsov ( Onagraceae), новый заносный вид для флоры Польши Текст научной статьи по специальности «Биологические науки»

передан в LE.). Популяция значительная, самодостаточная, нормальная. Новый вид для Амгуньско-го флористического района.

Corylus mandshurica - неморальный амуро-японский кустарник. Произрастает в Приморском и Хабаровском краях, в Амурской обл. (восточнее р. Зея). Встречается по Амуру до Мариинского (Усен-ко, 2009) - это была самая северная точка вида в Уссурийском флористическом районе. В.А. Недолужко (1996) указывает его только для Нижне-Зейского, Бу-реинского и Уссурийского флористических районов. С.Д. Шлотгауэр и др. (2001) в сводке по Хабаровскому краю приводят C. mandshurica для Буреинского, Уссурийского-Амурского и Сихотэ-Алинского флористических районов. И.Ю. Коропачинский и Т.Н.

Встовская (2002) проводят северную границу ареала где-то по Софийску (около 250 км к северу от г. Комсомольск-на-Амуре). Находка «передвинула» границу ареала на 300 км к северу от ранее упоминавшегося с. Мариинское, расположенного в 286 км к северо-востоку от Комсомольска-на-Амуре.

During my visit to the University of Warmia and Ma-zury in Olsztyn I have discovered in OLTC (OLS) herbarium three specimens of Epilobium pseudorubescens A.K. Skvortsov, an invasive alien new to Poland:

1) Tylkowko k/Pasymia, przy bazie "Energopolu", na osuszonym dnie stawu [ca. 20 km to SE from Olsztyn, Tylkowko fischery ponds, drained pond bottom], 16.VII 1999, M. Sroda (OLS 15277); 2) Michalki k/Pasymia, kom-pleks stawow rybnych "Michalki", staw po prawej stronie drogi Michalki - Miluki, blizej wsi Miluki, na osuszonym dnie akwenu [ca. 20 km to SE from Olsztyn, Michalki fishery ponds, drained pond bottom], 17.VII 2001, M. Sroda (OLS 16922) (a plant of E. pseudorubescens and a twig of E. adenocaulon); 3) Olsztyn, ok. 500 m na pd. od ul. Pilsudskiego i ok. 300 m na wsch. od ul. Bialostockiej na Osiedlu Mazurskim, oczko wodne ok. 1 ha, brzeg zach-odni [City of Olsztyn, SE part, bank of the water hole], 23.VII 2006, B. Korycinska (OLS 25642).

E. pseudorubescens is a member of E. ciliatum Raf. complex. This species was described by Skvortsov (1995) from Finland (with paratypes from Sweden and Russia), but its North American origin is discussed in the protologue. It was formerly known as E. rubescens

auct., but this name proved to be misapplied (Skvortsov, 1995). E. pseudorubescens is readily recognized from E. adenocaulon by white petals (slightly rose in buds), light green shoots, and lanceolate leaves (oblanceolate in E. adenocaulon). These two species are often found growing together, but no transitions were recorded in the mixed populations.

E. pseudorubescens is usually treated as a synonym of E. ciliatum s.l. in the European floras, but at least two separate taxa from this group are known to occur in the Eastern Europe (namely rose-flowered E. adenocaulon and white-flowered E. pseudorubescens). They are familiar to merely all Russian florists, and therefore history of their invasions is well-documented.

There is a gap of few decades between the invasions of E. adenocaulon and E. pseudorubescens. For instance, the first specimen of E. adenocaulon was collected in Vladimir Province of Russia in 1912 while E. pseudorubescens was collected here only in 1967 (Seregin, 2012). In Kaluga Province of Russia, the first record of E. adenocaulon dating back to 1909 is 66 years younger than a record of E. pseudorubescens (Reshetnikova et al., 2010).

White-flowered E. pseudorubescens is still unknown (or was discovered just recently) in many areas where E. adenocaulon is a common plant. Finland presumed to be a starting ground of E. pseudorubescens invasion in the Old World (Piispala, 1964; Vinogradova et al., 2009). It reached now the Black Sea Coast near Sochi on the southern limit and Khabarovsk Krai on the easternmost limit of its secondary range (Skvortsov, 1995; Seregin, Shved-chikova, 2008). However, E. pseudorubescens is known to occur in Siberia only in scattered localities in Tomsk, Kemerovo, Novosibirsk, and Irkutsk provinces, Krasnoyarsk, Altai, and Zabaykalsky krais (reviewed by Ebel, 2008). General history of E. pseudorubescens and E. adenocaulon invasions in Russia including maps and photos is published recently in Russian (Vinogradova et al., 2009).

At the moment, E. pseudorubescens is recorded from Sweden, Finland, Russia, Ukraine, Belarus, and the Baltic states. So, the records from NE Poland were predictable. It should be mentioned that E. adenocaulon was first recorded for Poland in Flora Polska (1959). Since that time E. pseudorubescens could be seen, but not recognised by the Polish botanists. I could assume that in other Polish herbaria one can find other specimens of E. pseudorubescens.
