Stems (25-) 60-100 (-130) cm, base usually simple-puberulent. Leaves mostly cauline; cauline leaves 3 or more, ± gradually smaller than basal leaves. Inflorescences 2-5 (-8) flowers per 5 cm, ± open. Flowers: sepals reddish purple to dark maroon, lateral sepals 8-12 mm, spurs (6-) 9-12 (-16) mm. 2n = 32.


Phenology: Flowering early-mid spring.
Habitat: Rock outcrops in open oak woods, grasslands
Elevation: 60-600 m
