Abstract

|
Rosae Laevigatae Fructus is a traditional medicine derived from the fruit of Rosa laevigata Michx. a member of the family Rosaceae. Rosa laevigata was recently reported as a new alien plant in Jangmok-myeon, Geoje-si, Gyeongsangnam-do. This study aimed to analyze and describe leaf, petiole, sepal, and petal epidermal cell patterns of Rosa laevigata using field emission scanning electron microscopy. The leaves of this species were hypostomatic, and the range of the size of the stomata was 16.5-25.9 × 16.0-20.3 μm. Epicuticular waxes and trichomes were not found on both surfaces of leaves; however, plate waxes were found in petioles only. Simple non-glandular trichomes were densely distributed on the outer side of the sepal and glabrous on the inner side of the sepal. Tabular rugose with longitudinal striations was found on the outer surface of the petal and papillose conical with striations on the inner side of the petal. These results will help understand future taxonomic works of the genus Rosa and the original species belonging to the family Rosaceae.
