This paper is here presented as a material for a flora of the Chinese grasses.  At the beginning, it chronologically gives a brief historical sketch on the study of the sub- tribe Isachninae.  The category which this group should constitute is here delimited, and its position in the natural system of grass-classification is also discussed.       Secondly it deals with a taxonomic treatment on the genus Isachne which comprises 16 species and 7 varieties in China, amongst which two species (I. hoi and I. hainanensis) and four varieties (I. albens var. glandulifera, I. truncata vars. crispa & maxima, and I. nipponensis var. kiangsiensis) are published here as new to science.  In addition, a new combination, I. hirsuta, (Hook. f.) Keng, f., based upon I. albens var. hirsuta Hook. f., is made here.  The two species (I. ciliatiflora Keng, and  I. tenuis  Keng)  published in Chinese only in the “Flora Illustralis Plantarum Primarum Sinicarum Graimeae 1959”, arehere supplemented with Latin diagnoses for validation.
