수목원 소장표본을 중심으로 한 국내 목본 식물의 분포지와 식별(IV) : 진달래과

Abstract

To clarify the taxonomy of two genera (Vaccinium andRhododendron) of Ericaceae, herbarium specimens collected from South Korea past forty years were examined on the basis of leaf, flower and fruit morphology. The qualitative and quantitative characters among Thododendreon taxa showed that ten taxa could be recognized. The current study rejected several varietal status R. mucronulatum var. taquetii, R. yedoense var. hallaisanense, R. brachycarpum var. tigerstedtii, R. brachycarpum var. roseum mainly proposed by Yamazxaki. On the other hand, R. parvifolium justified varietal status, i.e., R. lapponicum var. parvifolium (Adams) Yamazaki. Also, a plausible suggestion was that the entities of genera Oxycocus and Hugeria must be united and recognized under the genus Vaccinium. Results from this current study of Rhododendreon and Vaccinium in south Korea showed that R. brachycarpum, R. micranthum, R. dauricu, R. mucronulatum var. martimu, R. mucronulatum var. mucronulatum, R. mucronulatum var. ciliatum, R. tschonoskii, R. yedoense for. poukhanense, R. weyrichii, R. schippenbachii, V. koreanum, V. uliginosum, V. oldhamii, V. bracteatum, and V. japonicum were recognized respectively. Finally using a key and a limited sample of the Arboretum herbarium(SNUA) specimens to all taxa, the distribution maps were provided here.
