Abstract

Camphorosma monspeliaca subsp. lessingii (Litv.) Aellen (Amaranthaceae) has been analysed the anatomy of the root, stem and leaf with LM and SEM. The botanical material was fixed, freehand sectioned and stained according to usual microtechniques. The root was completely covered by xylem cells. The stem, in secondary growth, has the dermal system similar to the leaf; the angular collenchyma alternates with the chlorenchyma. The leaves are simple, entire, decussate, oval-lanceolate and purple, presenting uniseriate epidermis, pluricellular non-glandular trichomes coated by papillose cuticle, anomocytic and diacytic stomata on both surfaces; the mesophyll is dorsiventral, with collateral vascular bundles and druses. The results of the light and scanning electron microscope investigation revealed pollen grains of C. monspeliaca subsp. lessingii are polypantoporate, amb shape triangular, pollen shape spheroidal. Exine tectatae-echinate. The examined taxon has different levels of pore depth and convexness of mesoporial exine. Also the number of spines on the pore membrane and the density of the perforations and echinae on pollen surfaces are characteristic.
