| Research Abstract |
The comparative study of leaf morphology in Heteropappus hispidus and its ecotypic subspecies, H. hispidus ssp. leptocladus in serpentine soils and H. hispidus ssp. insularis in the coastal area, were conducted using morphological and anatomical approaches. The morphological analyses revealed that the leaf of H. hispidus ssp. leptocladus was more miniaturization and stenophyllization, and H. hispidus ssp. insularis has larger leaves than those of H. hispidus ssp. hispidus. Moreover, the anatomical analyses indicate that the leaf of H. hispidus ssp. leptocladus caused by decreased size and number of the cells but H. hispidus ssp. insularis also decrease the cell number though the cell size was increased.
