Comprehensive Description

Read full entry


Both the flowers and foliage are quite attractive. Large-Bracted Corydalis can be distinguished from other Corydalis spp. by its long yellow flowers (exceeding 2/3" or 15 mm. in length) and their large leafy bracts (exceeding 1/3" or 8 mm. in length). Other Corydalis spp. in Illinois have shorter bracts and/or shorter flowers. Large-Bracted Corydalis also differs from some Corydalis spp. by the crested protuberances behind the lips of its flowers (as opposed to protuberances that lack crests). In contrast to the seedpods of the similar Corydalis aurea (Golden Corydalis), the seedpods of Large-Bracted Corydalis are more erect and they lack constrictions between their seeds (they are not torulose). There are other varieties of Corydalis curvisiliqua, but they occur in states that lie southwest of Illinois.
