Abstract
コウライシバは, 葉の形態や生育場所からはっきりとコウシュンシバZoysia matrella(L.)Merr.から区別される別種と考えられるが, 従来コウライシバに当てられていたZoysia tenuifoliaが, コウライシバの学名として使用できないので, 新名Z.pacificaを提唱する。また, 西南日本での両種の分布域を明らかにした。
Zoysia matrella var. pacifica Goudswaard, is treated as a distinct species Z. pacifica M. Hotta & S. Kuroki. This species is easily distinguished from Zoysia matrella by folded, cylindrical, slightly succulent slender leaf lamina (ca. 1 mm in diameter). Dried specimens of Zoysia matrella has usually rolled leaf lamina which have similar appearance to folded cylindrical lamina of Z. pacifica. Living clones of Zoysia matrella, however, has narrow (1.5-2.5 mm wide) flat leaf lamina. A key that distingusihes Zoysia pacifica from Z. matrella is also provided.
