Abstract |
|
Morphological characters of section Acutae of the genus Carex(Cyperaceae) were reexamined. The epidermal patterns of perigynium, achene and leaf were investigated using by a scanning electron microscope(SEM) and a light microscope (LM). Morphological characters such as length and width of stem, leaf, bract, spike, scale, perigynium and achene, and shape of cross-sectioned stem, spike, scale, apex of scale. perigynium, beak of perigynium and achene, and epidermal pattern of perigynium, achene and leaf (shape of fundamental epidermal cell and cell wall, type of silica body, shape of beak epidermal cell and cell wall in perigynium, subsidiary cell shape, size and frequency of stomatal complex of leaf) were useful for the identification of the observed 11 taxa. C. cinerascens, C. heterolepis and C. forficular have been confused due to similar morphological characters. Co cinerascens, C. heterolepis and C. forficula were distinct, however with respect to from width of leaf, shape of scale, apex of scale, perigynium, beak of perigynium, and epidermal patterns of achene and leaf. |
