Ковыль волосовидный (Stipa Capilata I., Poaceae) - новый адвентивный вид флоры Беларуси

Abstract

The first record of the Needle-grass (Stipa pennata) for the flora of Belarus belongs to 1830 and applies to the territory of the former Minsk province. A little later in 1857 two species Stipa pennata and S. capillata are indicated without precise localities for the former Mogilev province. All these data are not confirmed by herbarium specimens and seems to be erroneous. Other literature sources belong only to the cultivated species. Since 1929, at least 12 species from 6 sections are cultivated in botanical gardens: Stipa capillata L., S. caspia K. Koch, S. caucasica Schmalh., S. extremiorientalis Hara, S. lessingiana Trin. et Rupr., S. pellita (Trin. et Rupr.) Tzvelev, S. pennata L., S. pulcherrima K. Koch, S. sareptana Beck, S. sibirica (L.) Lam., S. tenacissima L., S. ucrainica P. A. Smirn. In this article, European needle-grass – Stipa capillata is reported as alien species for the flora of Belarus for the first time. It was discovered in 2010 in the south-eastern part of the country in the Rogatchev province (Gomel region). A morphological description of the species, short characteristic of the new locality and total distribution are provided. In the discovered locality Stipa capillata occurred most likel as a wool-alien on waste land near the wool-wash enterprise. In Belarus Stipa capillata and potentially a few other species of needle-grasses will probably belong to the group of casual sometimes persisting aliens or can meet as occasional escape from cultivation (or persistent relic of cultivation).
