Content
Description
Leaves subbasal, longer than the stems, flat, stiffish, rough-margined, conspicuously septate-nodulose, long-acuminate, light or yellowish green, 6-10 mm wide.
Distribution
Asia-Tropical: Jawa (Jawa present); New Guinea present, Australasia: Queensland (Queensland present); Tasmania (Tasmania present), Eurasia present, Japan present, Kandep valley present, Kashmir present, Lake Habbema present, Lake Inin present, N. Africa present, New Zealand present, North and South America present, Terr. of New Guinea present, W. Europe present, W. Highlands present, W. New Guinea present, Wissel Lake region present, Yobobos grassland area present, almost worldwide present, eastern N. America present, northern hemisphere present
Carex pseudocyperus in the circumscription here accepted shows an almost worldwide distribution. The typical variety is widely distributed in the northern hemisphere (Eurasia from W. Europe to Kashmir and Japan, N. Africa, eastern N. America). Other varieties occur in North and South America; var. fascicularis in Australia (Tasmania to Queensland) and in New Zealand, in Malesia: New Guinea (W. New Guinea: Lake Habbema, Wissel Lake region; Terr. of New Guinea: W. Highlands, Kandep valley; Yobobos grassland area; Lake Inin). Specimens of this variety in BM and K are labelled "Java, Hofsfield"; recent collections from this island are not extant.
Notes
Var. fascicularis differs from var. pseudocyperus in its darker, ferrugineous glumes, its subinflated utricles with more divergent teeth to their beaks and longer stipe, and its contorted style.
The varieties certainly represent geographical races and might therefore better be considered subspecies. They are often treated at specific level, but the differences are so slight that it is here preferred to follow Boott (1867) and Kukenthal (1909).
