Anatomical comparison between cissus repens, cayratia japonica (vitaceae)‎ and leea aequata (leeaceae)‎

الملخص 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 repens and Cayratia japonica) and one species of Leeaceae family (Leea aequata) 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 repens and Cayratia japonica, however, in Leea aequata there was only druses crystals, except in lamina of Cissus repens , Cayratia japonica and Leea aequata in which there were druses and raphide crystals.

Leaf epidermis of Cissus repens, Cayratia japonica and Leea aequata 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 repens and Cayratia japonica had different types of stomatal apparatus such as cyclocytic and paracytic, and Leea aequata had anisocytic type.
