Resurrection of Fimbristylis campylophylla Tuyama (Cyperaceae)

Abstract

Fimbristylis campylophylla Tuyama with its variety, var. pygmaea Tuyama, has been treated by recent botanists as F. diphylloides Makino or its variety. As a result of my morphological and ecological studies, F. campylophylla is considered as distinct from F. diphylloides and F. campylophylla var. pygmaea is inseparable from F. campylophylla var. campylophylla. Fimbristylis drizae J. Kim & M. Kim described from Korea should be reduced to a synonym of F. campylophylla. Fimbristylis campylophylla is widely distributed in Japan and is newly found in Korea.
