Corydalis flavula is a species of plant found in North America in the subfamily of the fumigation plants (Fumarioideae) within the poppy family(Papaveraceae). The first description of this species was published in 1808 by Constantine Samuel Rafinesque-Schmaltz in Species Plantarum .
description
The green to bluish green, annual herbaceous plant has one to several stems that reach heights of 15 to 30 centimeters; these are erect in youth, later often prostrate. The foliage leaves that grow on the base of the stem are long-stalked, the leaves that grow further up have short-stalked to sessile and hardly reduced in size. The leaves are pinnate and consist of five to seven leaflets, which in turn consist of up to five incised leaflets. The outermost leaf segments are narrow to broadly elliptical, pointed, very different in size.
The racemose inflorescence consists of six to ten or more flowers, it hardly grows beyond the leaves; the flowers are sometimes poorly trained, one to fünfblütige grapes cleistogamic flowers - if available - are normal. The flower stalks are slender and 6 to 15 millimeters (and more) long. The sepals thin, lanceolate, glutinous and about 1 millimeter long. The crowded flowers are pale yellow, the spurred petals are 7 to 9 millimeters long, the unsporn petals 6 to 8 millimeters long. The fruits are 14 to 22 millimeters long, the black seeds up to 2 millimeters.
The flowering period extends from mid-March to mid-May, the fruiting period from early April to early June.
The number of chromosomes is 2n = 16.
