Abstract
Morphological characters of 14 taxa in 6 sections Ischnostachya(one taxon), Anomalae(one taxon), Capitellatae (five taxa), Debiles (one taxon), Capillares (one taxon) and Molliculae (five taxa) of genus Carex (Cyperaceae) were reexamined. The epidermal patterns of perigynium, achene and leaf were investigated using by using a scanning eletron microscope (SEM) and a light microscope (LM). Morphological characters such as rhizome, spike, width of leaf, leaf sheath, involucre, involucre sheath, beak of perigynium, perigynium shape, and leaf epidermal patterns were useful for the identification of observed fourteen taxa. The number of spike, arrangement of psitillate or staminate spike and presence of bract were very useful characters to divide the treated 14 taxa into two groups. A key based on data was presented here.
