개서어나무(자작나무과 서어나무속) 동아

2014. 1. 4. 경남.

 

동아와 수피로 서어나무와 구분하기 까다롭지만 가장 쉬운 방법은

전년지의 밀모를 확인하는 방법이다.

서어나무는 거의 털이 없거나 약간 있는 정도이지만 개서어나무는 부드러움 털이 밀생하고 있다.

 

서어나무에 비하여 잎 표면과 잎 뒷면에 복모가 있고 열매가 크고 과포 한쪽에만 톱니가 있다.

 

헌데 열매 포의 크기가 대형(2.5~2.8cm)인 왕개서어나무(, 전남, 경남,지리산, 통영, 함양,)와

소견과의 윗부분이 화피 밖으로 나오는 당개서어나무(지리산, 백양산)가 더 있는데 아직 확인하지 못하고 있다

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

수피의 근육질은 서어나무보다 평활한 편이다.
