NAPÆA, in botany: A genus of the polyandria order, belonging to the polydelphia class of plants; and in the natural method ranking under the 37th order, Columnifera. The calyx is single and cylindric; the
Naphtha, the arilli coalited and monospermous. There are two species; both of them with perennial roots, composed of many thick fleshy fibres, which strike deep into the ground, and are connected at the top into large heads; the stalks grow to seven or eight feet high, producing white flowers, tubulous at bottom, but spreading open at top, and dividing into five obtuse segments. Both these plants are natives of Virginia and other parts of North America: from the bark of some of the Indian kinds a sort of fine hemp might be procured, capable of being woven into very strong cloth. They are easily propagated by seed, which will thrive in any situation.
