The lark spurs ( Corydalis ) form a genus of plants in the subfamily of the fume family (Fumarioideae) within the poppy family (Papaveraceae).

Appearance and leaves

Corydalis species are annual to perennial herbaceous plants . Tap roots, tubers or rhizomes are formed as persistence organs. The simple or branched stems are erect or creeping. The leaves are mostly composed, but also simple. When the leaves are put together, they are two to six pinnate or lobed.

Inflorescences and flowers

The flowers are in terminal or axillary, paniculate or racemose inflorescences . The hermaphrodite flowers are zygomorphic . The two small sepals fall off early in some species. The four petals standing in two circles are free or fused at their base; the two inner ones are also fused together at the top. The upper petal forms a spur at its base. This spur, which gives the larkspur species a certain resemblance to the crested lark ( Galerida cristata ), led to the common German name "Lerchensporn" (the rear toe nail (rear claw) of the skylark is also known as the larkspur). There are six stamens . The stylus ends in a two-part scar.

Fruits and seeds

In contrast to Fumaria (single-seeded nut ) , the fruit is a two- compartment pod that contains a few or many seeds. The mostly shiny black seeds usually have an elaiosome . Some Corydalis species (species with a tuber , such as Corydalis cava ) have only one cotyledon . The other species have, as is usual with the dicotyledons , two cotyledons.
