Anatomical and palynological studies of cissus quadrangularis and Cayratia Geniculata (vitaceae and leea Angulata (LEEACEAE)‎

Abstract EN

This study was conducted to evaluate anatomical comparison between three species belonging to two families (Vitaceae and Leeaceae).

Two genera of the family Vitaceae (Cissus quadrangularis and Cayratia geniculata) and one species of Leeaceae family (Leea angulata) were investigated.

Anatomically it has been shown that the shape of stem, petiole, midrib, margin and lamina were different.

There were druses and raphid crystals in stem, petiole, midrib, margin of Cissus quadrangularis and Cayratia geniculata, however, in Leea angulata there was only druses crystals, except in lamina of Cissus quadrangularis, Cayratia geniculata and Leea angulata in which there were druses and raphid crystals.

Leaf epidermis of Cissus quadrangularis, Cayratia geniculata and Leea angulata were investigated by using light microscope and scanning electron microscope.

The shapes of leaf epidermal cells were usually polygonal; the types of anticlinal walls are straight and arched.

The stomatal apparatus presented on the both side of the leaf (abaxial and adaxial).

Cissus quadrangularis and Cayratia geniculata had different types of stomatal apparatus such as cyclocytic and hemiparacytic, and Leea angulata had anisocytic type.
