| ABSTRACT |
|
Two Korean species of Anotrichium was taxonomically investigated, referred to their subgeneric groups, A. furcellatum (J. Ag.) Baldock was characterized by the tetrasporangia borne singly on nonforked nodal cells and the elongate capillary vegetative cells in 10-15 times as long as broad. A. tenue (C. Ag.) Naegeli was characterized by peculiar branching mode, decumbent habit, and unicellular rhizoids. The latter species was divided into three varieties by morphological characters; A. tenue var. tenue for Mediterranean plants, A. tenue var. secundum (Harvey ex J. Ag.) Stegenga for South African plants and A. tenue var. thysigerum (Thwaites ex Harvey) Kim et Lee, var. nov. for Atlantic to Indo-Pacific plants. According to the present investigation, the genus can be divided into two subgenera, resurrecting Naegeli's proposal; Anotrichium (= Euanotrichium) including A. barbatum and A. elongatum group sensu Baldock, and Corynosporium for only one species A. tenue previously included in A. barbatum group sensu Baldock.
