The Ethnobotany 551<br />

to Diggs et al. (1999) the plants contain a poisonous<br />

saponin that causes photodermatitis.<br />

Fruits have been substituted for hops in making<br />

beer since at least 1868 when Asa Gray recorded that<br />

use (Hedrick 1919, Vines 1977).<br />

Pteridium<br />

natural history in Pavia, named the fern with Greek<br />

Pteridium aquilinum (of an eagle, from the wingshaped<br />

fronds or leaves)<br />

Although Moerman (1998) and Balick et al. (2000)<br />

separate Pteridium aquilinum var. caudatum into<br />

Pteridium caudatum, Wunderlin (1998) retains both<br />

as a single species. Regardless, P. aquilinum is widespread<br />

and was used by people from Alaska to Mexico<br />

and Florida. Among the relatives of Florida people,<br />

the Koasati made a decoction of the roots for chest<br />

pain (Taylor 1940). The Seminoles used the plant for<br />

‘‘Turkey Sickness’’ (permanently bent toes and fingers)<br />

(Sturtevant 1955). Murphee (1965) found people in the<br />

Panhandle making a tea from the plants to treat burns.<br />

Farther north, the steamed mature fronds are used<br />

to make medicinal teas and inhalants for lung<br />

disorders and headaches (Moerman 1998). The young<br />

buds (fiddleheads) are edible. Older parts are poisonous<br />

(Morton 1968b), and King (1984) warns against<br />

using it for food at any stage. Yellow and green dyes<br />

are extracted from the roots (King 1984, Tull 1999).<br />

Pterocaulon: Blackroot<br />

(From Greek pteron, wing, plus kaulos, stem)<br />

Within the United States, there are relatively few<br />

plants whose roots yield a black sap. The two in the<br />

southeast are called ‘‘blackroot.’’ Scientifically, the<br />

herbs belong to the genus Pterocaulon. The green<br />

leaves with their white undersides merging into the<br />

stem and extending downward toward the ground, like<br />

wings, are as characteristic as their black roots. The<br />

first information Europeans had of these plants was<br />

when Linnaeus called them Gnaphalium virgatum in<br />

1759. However, it was Stephen Elliott, an American<br />

professor in Charleston, South Carolina, who gave<br />

them the Greek name fitting their morphology in<br />

1823.<br />

For many years, it was believed that a single<br />

species grew in the United States, and it was called<br />

P. virgatum. Then, when the Frenchman André<br />

Michaux, who explored the Carolinas and Florida,
