English Abstract

Trips started during 2013 revealed the presences of three species from Mimosaceae in Kurdistan – Iraq: Two of them occur in cultivation [Prosopis juliflora (Sw.) DC.

and Acacia Cyanophylla Lindl.] and one (Prosopis farcta Banks et Sol.) is growing naturally.

The anatomical study includes leaf blade and petiole cross sections.

Results revealed that the phyllode is isobilateral, while P.

juliflora and P.

farcta are dorsiventral.

Two-layered palisade parenchyma exist in A.

cyanophylla both abaxial and adaxial faces immediately beneath the epidermis.

One layer in P.

juliflora and two layer layers in P.

farcta, each at adaxial face only.

In the Phyllode, the central region located between the palisades layers consist of ground tissue of thin-walled parenchyma cells.

Many minor collateral bundles are embedded in the ground parenchyma.

Each bundle directs the xylem to the upper and lower surfaces alternately.

In P.

juliflora and P.

farcta the spongy parenchyma exists at the abaxial face with xylem oriented towards the adaxial face and phloem towards the abaxial.

P.

farcta leaves show great differences from that of P.

juliflora in respect to number of palisade layers, structure and shape of mesophyll.

In the petiole cross section of P.

juliflora and P.

farcta, there is a single-stranded vascular bundle.

Only in P.

juliflora there are two more secondary wing bundles.
