| Abstract: | Studies have indicated that Peganum possesses very striking xeromorphic structures,for example,roots possesses developed periderm,more than 2 rings of anomalousvascular bundles exsite in axis organs,with crystal cells and water storage tissues,theleaves belong to ring-palisade in structure and palisade tissues are well developed. It issuggested that these structural characters might have important ecological value to adaptxeric habitat. |
