Phenology: Fruiting early May–Jun.
Habitat: On well-drained soils of seasonally wet stream banks
Elevation: 700–1000 m
Of conservation concern.
Carex aboriginum was not seen from the time of its original collection in 1899 until its rediscovery, in the vicinity of the type locality in 1999 (C. Bork 2000), and at a nearby site in 2000. The abundant new material matches the type specimens in all respects. On the basis of the type alone, F. J. Hermann (1970) considered C. aboriginum to be very close to C. serratodens, which the new specimens support. Carex aboriginum has pistillate spikes with perigynia clearly larger and staminate spikes on longer peduncles. These morphologic distinctions and the disjunct distribution of C. aboriginum from the main range of C. serratodens argue for provisionally maintaining it at the rank of species until sufficient specimens are available to permit a reëvaluation of variation. The illustration in K. K. Mackenzie (1940) as C. aboriginum is of another species.
