NAPÆA, in botany; a genus of the polyginia order, belonging to the monadelphia class of plants. 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.
