Initial growth is in the form of a basal rosette with a single flowering stem produced the second year. This stem is unbranched below the inflorescence and leafy throughout. Upper leaves are alternate, numerous, not reduced or larger, acute to obtuse, and sessile or clasping.
All leaves are pubescent on upper and lower surfaces.
Flowers are perfect and in racemosely arranged cymes axillary to the leaves or on terminating short branches, pedicellate, crowded at anthesis, less crowded in fruit. The throat of the corolla bears five hairy scales. Five stamens are inserted into the upper part of the tube. The pistil consists of a deeply lobed ovary and simple style. Fruit is indehiscent and consists of one to four nutlets.
