Resumen:
This study evaluates the leaf anatomy pattern
of Gaillardia cabrerae Covas, an
exclusive endemic camephyte from the Lihué Calel National Park, province
of La Pampa, Argentina. Leaf cross sections and peelings of plants growing in
two different populations were used to determine the basic leaf anatomy patterns
and to estimate the influence of growth conditions in the two microhabitats.
The analysis showed differences in epidermal cells area, stomata density and
main diameter, lacunar parenchyma cells and central vascular bundle diameter
and palisade parenchyma cells dimensions. These aspects might be reflecting
environmental conditions of the populations, especially sun exposure and soil
moisture. The results provide information on the relationship of the species to
its environment, which could be used in the establishment of conservation policies.
