Carex richardsonii is named in honor of its discoverer, Sir John Richardson who was alive from 1787 to 1863 (Fernald 1970).
|State Ranking Justification||
There is only a single specimen of Carex richardsonii from New York. This was collected in the late 1800 from a site "eleven miles west of Rochester in the town of Greece." Despite multiple surveys, this site has not been relocated. While the only known site is probably extirpated, this sedge may be present in the alvar region near the eastern shore of Lake Ontario.
No populations of Carex richardsonii have been seen in NY in over 100 years and therefore, short term trends are unknown.
The only population of C. richardsonii known from New York is believed extirpated. Therefore, long term trends show a sharp decline.
