Series: Images of a botanical trip to the Free State of Thuringia (German: Freistaat Thüringen) in Germany from 15 - 19/04/2011
Corydalis cava (NL: Holwortel / EN: Bulbous Corydalis / DE: Hohler Lerchensporn)
Between March and early April Corydalis cava develops variable-colored, slightly fragrant flowers. In every population there is roughly an equal amount of purple and white flowering specimens. The flowers are in a terminal ten-to 20-flowered and dense inflorescence. Below each flower are oval to ovate, entire bracts. In Corydalis solida - a very similar species, these bracts are divided. An individual flower is about 2 to 3 cm long. The botanical name derives from the Greek word "κορύδαλις" - "korýdalis" meaning "From the Crested Lark (Galerida cristata) because the flower shape is similar to the spurred toe of this bird. The Latin word "cava" means "hollow" and refers to the hollow tuber of the plant.
