한국의 물오리나무(Alnus hirsuta var. hirsuta)와 물갬나무(A. hirsuta var. sibirica)의 분류학적 재고

Abstract

Fruit specimens with leaves of 45 specimens were sampled to investigate patterns of interspecific variation and to evaluate recognition of Alnus hirsuta var,. hirsuta and A, hirsuta var. sibirica taxa using eight leaf and fruit characters. This study suggested that leaf characters (length and width) were no longer useful for identification, but fruit width, andgle of leaf, bud length, and fruit shapes were useful to tell A. hirsuta var. hirsuta from A. hirsuta var. sibirica. Our data showed that A. hirsuta var. sibirica was mainly distributed in eastern Korea. However, A. hirsuta var. hirsuta was distributed in eastern Asia area(China, Russia, Korea, and Japan).
