Abstract To be able to deseribe the structure and functioning of Miscanthus sinensis grassland, its floristie composition, life-form spectra, stand productivity and dry matter allocation were studied. 43 species were to be found during the growing season of 1976. 29 species, and 345 individuals per 1 m2, were observed in the sample areas in September. The values for standing crop of constituent species have been arranged in ascending order. The dominant Raunkiaer life-forms were the hemicryptophyte and geophyte. The stand was characterized by erect and tufted forms in Numata's system of growth form classification. The standing crop of the whole stand decreased from April to June, then increased from mid-July. The maximum standing crop of 3346 g m-2was observed in September. The net production of the stand was 959.4 g m-2year-1. Fifty one percent of this net production was allocated to the underground organs which consume it for respiration during winter and for initial growth in the next growing season.
