Morphological and anatomical analysis of Angelica silvestris L. and Angelica arhangelica L. leaves
Angélica’s genus has about 60 species. The most common of them in Ukraine are Angelica archangelica L. and Angelica sylvestris L.
The aim of our research has been to investigate the morphological and anatomical structure of Angelica arhangelica L. and Angelica silvestris L. leaves, to determine their diagnostic features.
Angelica archangelica L.: the leaves are large, stalked, twice or three times pinnate, with large ovoid lobes, serrated edge. Leaf is slightly pubescent with simple hairs. Edges of the leaf are beneath.
Upper epidermal cells are elongated, with slightly sinuous shells. There are expressed nipples in some areas. Parenchymal cells of the lower epiderm are thin with membranes strongly sinuous and have numerous stomata. Type of stomata is anomocytic.
Angelica silvestris L.: leaves are petiolate, twice or three times pinnate, with large oblong ovate lobes, sharply serrated edge. Hairy leaf with simple hairs differs in shape, thickness of shells, and number of cells. Upper epiderm cells are different in shape (from polygonal to triangular) and sizes, with straight-side thickened shells, arranged radially. The cells of lower epiderm are parenchymal, with slightly sinuous membranes, thin-walled, with numerous stomata. Type of stomata is anomocytic.
As a result of macro- and microscopic analysis, the basic diagnostic, morphological and anatomical features of Angelica silvestris L. and Angelica arhangelica L. leaves have been defined, which will be used to identify new medical plants material.
