Abstract

Olesya O. Bezsmertna, Natalia V. Nuzhyna

The comparative analysis of structural features of some morphological characters has been conducted. Anatomic peculiarities of petioles of Asplenium × souchei Litard. and its parental forms (A. obovatum Viv. subsp. billotii (F.W. Schultz) O. Bolòs, Vigo, Masalles & Ninot and A. septentrionale (L.) Hoffm.) in correspond with systematics are mentioned. Accordingly to the morphologic peculiarities of leaf blade (shape and dissection) of A. × souchei is closer to A. obovatum Viv. subsp. billotii than to A. septentrionale. But the anatomic structure and cross-sectional shape of petiole of A. × souchei place this species closer to A. septentrionale. The species A. × souchei we recommend to include in the next edition of the Red Book of Ukraine.
