수목원 소장표본을 중심으로 한 국내 목본 식물의 분포지와 식별에 대해서 (VII) : 갈매나무과에 대해서

Abstract

To clarify the taxonomy of Ramnaceae, herbarium specimens collected from South Korea were examined on the basis of leaf, flower, and fruit morphology. The qualitative and quantitative characters showed that 13 taxa could be recognized. The current study could not confirm the existence of Rhamnus utilis Decne., R. diamanticus Nakai, and R. parvifolius Bunge in South Korea. On the other hand, R. davuricus var. nipponicus justified a species status as R. ussuriensis J. Vass due to the presence of thorn in the winter terminal bud. Also, a plausible suggestion was that Berchemia wilsonii in central China may be recognized as a synonym of B. berchemiaefolia in Korea and Japan. Results from this current study showed that B. racemosa justified the old name of B. floribunda in China. Finally using a key and a limited sample of the Arboretum herbarium specimens (SNUA) to all taxa, the distribution maps were provided here.
