In the Violet tribe there are two types of growth-There are stemless violets and violets with true stems: it'- as simple as that, their division. The so-called stemless violets are like the common blue violet and many others which have leaves and flowers on separate stalks rising from the true stem. This is really a thick, gnarly rootstock growing horizontally in the ground. The stemmed violets have true stalks which rise from a fibrous root. Leaves are placed alternately upon the forking stem, and the flowers on thin petioles spring from the axils of the leaves. These flowers produce seeds; in the stemless violets, the colored flowers seldom make seeds. Instead, in summer they produce short-stalked, green, fat, seed-making flowers which have no petal-. These are called cleistogamous flowers; they make large quantities of seeds. These are dispersed when the three-parted pods burst in late summer and they usually germinate in great abundance to make many new violet seedlings.
Viola pedatifida G. Don.
April - May Prairie roadsides.
One of the stemless species is the prairie violet. It- flowers are light lavender-blue with a white-furred throat. The} stand on long thin stems above the leaves which appear almost as if someone had taken common blue violet leaves and with scissors had lobed them deeply. The leaves of Viola pedatifida somewhal resemble the -till more deeply cut leave- of the bird-fool violet, but the flowers are not large and their shape and color prove them to he true prairie violet- instead. They are found on open prairie soil between the railroad track- and highways in many place- in the state.
