The APG IV system of 2016 (unchanged from the earlier 1998 APG system, the 2003 APG II system, and the APG III system of 2009) includes the former family Fumariaceae within the Papaveraceae. (wikipedia.org)
Corydalis6
The largest genus is Corydalis (with 470 species). (wikipedia.org)
All Corydalis species are delicate, low-growing, and sometimes form mats. (mo.gov)
There are four species of Corydalis in Missouri, and they are quite similar in appearance. (mo.gov)
Also, although the other corydalis species flowers range from pale yellow to bright yellow, this species' flowers are always bright yellow. (mo.gov)
All our corydalis species may be found along roadsides and streams. (mo.gov)
Our other three corydalis species otherwise tend to occur in drier, more upland sites, such as prairies, glades, savannas, openings in dry upland forests, and so on, and some prefer acidic soils. (mo.gov)
