Description (according to IHSP 2003) :

 

Basal leaves peltate, to 7 cm in diameter, cauline leaves ± lanceolate, becoming linear in the inflorescences.

 

Inflorescences dense simple racemes to 1 m but mostly less, somewhat secund, floriferous part to 35 cm, pedicels to 3 mm.

 

Flowers horizontal or drooping, corolla tubular, costate, bright yellow, 10 - 12 mm, stamens usually 5.

 

This is the most distinctive European taxon, distinguished by its relatively tall stature, the bright yellow costate corolla tube strongly constricted at the mouth, and by the reduction in number of stamens.
