دراسة مورفولوجية وتشريحية للنوعSerapias vomeraceae من الفصيلة السحلبية (Orchidaceae)

Abstract

This research includes a study of the patterns of epidermal cells, stomata, and shapes of calcium oxalate crystals, in addition to the patterns of trichomes and papillae in different parts of the species Serapias vomeraceae (Orchidaceae).

The results showed a diversity of epidermal cell patterns in the leaves, ranging from rectangular to polygonal shapes, and a high density of secretory cells, especially on the side of the stomata, which were of the Anomocytic (abnormal) type, while only the Tetragonal shape was observed in the bracts, and the polygonal shape in the sepals and Labellum.

By studying the forms of calcium oxalate crystals, we were able to distinguish the Styloid and Druses shapes in the leaves, while the Druses shape was only observed in the bracts, sepals, petals, and Labellum.

The petals showed the presence of unicellular, unbranched, conical glandular trichomes, and we were able to distinguish two types of hairs on the Labellum: the first type is vertically glandular on the edges of the Labellum, and the second type is granular on the upper surface of the Labellum.Top of Form
