From the Himalayan region to Annam, Manchuria, Korea, Japan, and extending as far north as Sachalin (var. sachalinensis Ohwi); through Malesia to Australia (New South Wales) and New Zealand; in Malesia: Sumatra (North: Atjeh; Central West: G. Singalang), W. Java (Mt Papandajan), N. Borneo (Mt Kinabalu), SW. Celebes (Mt Rante Mario), Philippines (Luzon), and New Guinea.


Closely related to the Indian C. rara Boott. Boott distinguished C. capillacea from C. rara by the capillary stems and leaves, the shorter, ovoid spikelet, the smaller, reflexed, puncticulate utricles, and the caducous glumes. Except for the much longer, linear spikelets (male part much longer than the female one), and the suberect utricles of C. rara, these characters are unreliable. The two might possibly better be regarded as subspecies of a single species.
In typical C. capillacea (var. capillacea) the stems and leaves are filiform and the utricles 2-2.5 mm long. The above description comprises also stouter plants with leaves up to 2 mm wide and utricles 3-4 mm long, which have been distinguished as var. sachalinensis (F. Schmidt) Ohwi.
