The species name honors William Oakes (1799-1848), a famous New England botanist who first collected this plant. His career was cut short when he fell overboard from a ferry boat between Boston and East Boston and drowned. His name was used for another New York rare plant, Oakesia conradii, which later was changed to Corema conradii.
|State Ranking Justification||
There are six existing populations but only two of them have more than 100 plants. Their locations are in disturbed areas which may have a larger effect on population sizes from year to year. There are 26 historical occurrences but many of these have probably been extirpated by development of the open sandy areas.
Existing populations seem to be stable at low numbers but most populations have only been surveyed once.
Populations seem to be declining from historical numbers but this species is difficult to identify and may move around from one disturbance to another so trends are difficult to assess.
