Ophioglossum vulgatum, var. crotalophoroides, E aton, in Chapman’s
Ploi-a, p. 599.
Mab.— Old fields and low sandy grounds from South Carolina and
Florida to Louisiana. Dr. Garber found it at Manatee, Florida, and
Professor E ugene A. S m ith reports it as being abundant near Tuscaloosa,
Alabama. The range extends to Chili, and possibly much farther.
P ursh says, “ New Jersey to Carolina,” but no one in recent years has
detected it in New Jersey, and it may be doubted whether it was ever
found there.
D e s c r i p t i o n : — T h e root-stock is so lid and sub-globose,
two to fo u r line s thick, and fu rn ish ed w ith a few com m on ly
de scend ing roots much s lend ere r than those o f O. vulgatum.
