ANATOMICAL ASPECTS OF CHLOROPHYTUM COMOSUM (THUNB.) JACQUES „VARIEGATUM” (ANTHERICACEAE) PUBLISHEDRodica Bercu
The article comprises the investigation of the adventitious root, the aerial stoloniferous stem and leaf anatomy of a verypopular houseplant , native of the tropical and subtropical regions of South Africa Chlorophytum commosum ( Thunb. ) Jaques 'Variegatum'. The mature root possesses a typical monocot’s prymary structure with numerous vascular bundles but possessing few xylem and phloem elements. The aerial shoot stele is atactostelic with poor developed collateral bundles, composed of xylem and phloem. The blade mesophyll of Chlorophytum commosum is homogenous with poorly developed vascular bundles veins. The stem and blade epidermis is covered by a thick cuticle. The leaf and shoot epidermis continuity is interruptured by the presence of stomata. The poorly developed vascular system (in the adventitious root, shoots and leaf), the few mechanical elements of collenchyma, present in the aerial stolons and some sclerenchyma cells in the blade are in accordance with the plant pendant condition.
