June 1967 The Journal of Geobotany Vol. XV. No. 4 And in 1965 the writer newly found this sedge at Hirao-dai plateau in north­

em Kyusyu of Japan.

Each of the Japanese localities listed above lies on limestone area, while Middle China and South Korea are presumed to have limestones or chalky soils at the place where this sedge grows. On the other hand, the distribution map of the sedge (Fig. 1) shows some resembrance to IwATSUKI

s map of Hypodema­

tium, a fern genus, which is well known as a limestone dweller. From these facts, it is probable to say C. poculisquama one of the calcicolous relics.

So far as it is observed at Akiyoshi-dai and Hirao dai plateau, this sedge is found only in the sunny grassland, though in乱1iddle China KiJKENTHAL wrote the specimen had collected in a forest or in a dark forest. As is shown in Table 2, here in Japan this sedge seems to have high fidelity towards Arundina­

ria ( =Ple1

oblastus) community. And the community spreads over more or less dry or rather poor soil which is caused by the yearly fire set on the plateau in order to regenerate the grassland. By the way, it is noticeable that Fimbristylis pierotii has also rather high fidelity towards such a community.

C. poculisquama rises in the same pace with the growth of Arundinaria species, grasses or other herbs in the community, finally attaining to as tall as a meter near the end of July when it comes to its full development.
