It is a perennial herb producing an erect flowering stem from a patch of basal leaves. The leaf has a rounded blade at the end of a long petiole, the leaf reaching a total of up to 16 centimeters long. The inflorescence may be up to 40 centimeters tall and consists of a mostly naked peduncle with one clasping bract midway up.
