북편 응달 삿갓우산이끼 가득한 사이에 뱀톱이 파랗게 꼬리를 치켜세웠다.
석송과 중 하나인 뱀톱은 포자를 터뜨리는 양치식물로 줄기 끝의 무성아가 떨어지면서 번식을 한다.
윗부분 끝의 무성아는 떨어지면 싹이 돋고 짙은 녹색이며 길이 5mm로서 3개의 작은 육질엽으로 싸인다.
아래 그림에서 삐죽한 용머리 형상을 한 것이 무성아이다. 엽액의 포자낭은 벌써 터져서 홀씨는 다 날아 가 버린 것 같다.
잎은 총생하며 옆으로 퍼지거나 밑으로 처지고 좁은 피침형으로서 선명한 녹색이며 편평하고 길이 6~20mm, 폭 1~5mm 정도이다.
중륵이 뒷면에서 뚜렷하고 가장자리에 불규칙한 톱니가 있으며 밑부분은 좁아져서 자루같고 끝이 뾰족하다
