The leaf blade of lower leaves ovate - cordate, above they are more elliptical- lanceolate. The sheet-like side sheets are only slightly broadened, with four or six side portions, and with a more or less linealischen always ganzrandigen end portion.
The slender stems usually wears one, but sometimes up to four flowers. The five 1.5 to 3 cm wide, zygomorphic, hermaphrodite flowers grow on long stems and little smell. The outstretched petals are yellow, purple or mixed colors. The petals are much longer than the sepals. The seated on the lowest petal spur is about half as long as the petals. The flowering time is June to August. Pollination is mainly by insects.
