Polygala nodiflora (Polygala nodiflora)
Description
Polygala includes annual and perennial plants, shrubs, vines, and trees. The roots often have a scent reminiscent of wintergreen. The leaf blades are generally undivided and smooth-edged, and are alternately arranged in most species. The inflorescence is a raceme or spikelike array of several flowers; the occasional species bears solitary flowers.The flower is bilateral in shape, with two large petal-like sepals on the sides, often called the "wings", and three smaller sepals behind. There are three petals in shades of reddish purple, yellow or white, which are joined at the bases. The lower of the three is the keel petal, which is "boat-shaped, cucullate [hood-like], or helmet-shaped". The keel petal may have a beak or a fringe on the tip.Stamens and style are within the curve of the keel petal. The fruit is a capsule, sometimes winged. It contains 2 seeds which are usually black, hairy and tipped with a large white aril. One polygala is the Fringed Polygala, found in coniferous forests
