Stem simple or sparingly branched, erect, smooth, 8 to 20 inches high. Leaves usually opposite, lanceolate or oblong-lanceolate, sharp pointed at both ends, nearly sessile and usually dotted with black, 1 to 3 inches long, one-sixth to two-thirds of an inch wide; often bearing, after flowering time, long bulblets (suppressed branches) in the axils, especially in the autumn. It was this condition that was mistaken by Linnaeus for a Mistletoe, under which group he originally classified it. Flowers one-fourth to one-third of an inch broad, chiefly in the axils of the upper and smaller leaves and forming a terminal leafy raceme; stalks of the flowers slender, one-half to threefourths of an inch long; sepals long-ovate, pointed; corolla rotate, parted nearly to the base, usually into five segments, yellow with purple streaks or dots. Fruit a capsule about one-eighth of an inch in diameter.
