Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 to >300
Comments: A total of 77 extant EOs are known, but the total is likely over 100 because this plant is sufficiently common not to be tracked in Oklahoma and Texas. For Stylisma pickeringii var. pickeringii, 62 extant occurrences are known, from the following states: New Jersey (11), North Carolina (36), South Carolina (7), Georgia (6), and Alabama (2). (Information was gathered from the 1993 EGR for this variety, plus additional records through 1995 for North Carolina and Alabama.). For S. pickeringii var. pattersonii, 15 extant occurrences are known from the following states: Illinois (4 post-1970), Iowa (1 post-1950), Missouri (2), Kansas (3 post-1970), and Arkansas (5). The variety pattersonii is also known from Mississippi, where it is rare, and reported from Oklahoma and Texas, where it is fairly common in sandy, open ground (Poole pers. comm. 1996).
