ANATOMICAL VARIATIONS IN LEAVES OF BOESENBERGIA O. KUNTZE AND KAEMPFERIA L. SPECIES (ZINGIBERACEAE)
凹唇姜属(Boesenbergia O.Kuntze)和山柰属(Kaempferia L.)(姜科)叶的解剖学

Leaf anatomical variations between species of Boesenbergia (B. curtisii, B. prainiana B. rotunda and B. plicata) and Kaempferia (K. pulchra, K. galanga, K. gilbertii, K. rotunda, K. parviflora and K. angustifolia) were studied in order to investigate anatomical variations which could be used to distinguish species. Results show that there are variations in the type of stomata, the structure of the midrib, the outlines of the leaf margin and petiole in transverse section, and the presence or absence of abaxial or adaxial hypodermis and trichomes in the lamina. The results suggest that a combination of these characters is useful in distinguishing the species studied.
