(2) The natural populations of the species in Ohio are limited to three or fewer occurrences.

(3) The distribution of the natural populations of the species in Ohio is limited to a geographic area delineated by three or fewer United States geological survey 7.5 minute quadrangle maps.

(4) The total number of plants in all the natural populations of the species in Ohio is limited to one hundred or fewer individual, physically unconnected plants.
