Morphological characters of 16 Korean taxa of two sections (Fimbristylis, Michospora) of the genus Fimbristylis (Cyperaceae) were reexamined. The epidermal patterns of achene and leaf were investigated using a scanning electron microscope (SEM) and a light microscope (LM). The scientific and Korean names were reviewed and a key based on these characters was provided. Morphological characters (length and width of stem, leaf, leaf sheath, spikelet, achene, scale and bract, and shape of cross-sectioned stem, spikelet, achene, apex of scale, and number of bract) and epidermal patterns of achene and leaf (shape of achene, leaf epidermal cell, cell wall, silica body of leaf, size and frequency of stomatal complex, and subsidiary cell shape) were useful for the identification and classification of the taxa. Fimbristylis aestivalis Vahl was newly recorded in Korea, while taxonomic positions and Korean names of F. complanata (Retz.) Link f. exalata T. Koyama, F. autumnalis (L.) Roem. et Schult., F. dichotoma (L.) Vahl, F. dichottana (L.) Vahl f. floribunda (Miq.) Ohwi, F. dichotoma (L.) f. tomentosa (Vahl) Ohwi, F. globulosa Kunth var. austrojaponica Ohwi, F. longispica Steud., F. miliacea (L.) Vahl, F squarrosa Vahl, F. squarrosa var. esquarrosa Mak., F. tristachya R. Br. var. subbispicata were clarified. On the other hand, F. dichotoma Vahl, F. dichotoma f. floribunda, and F. dichotoma f. tomentosa were distinct from each other regarding length of stem, leaf sheath, leaf and bract, shape of cross-sectioned stem and shape of epidermal cell of leaf. |
