Malheur Valley fiddleneck is an erect annual, 10-50 cm tall, glabrous to mostly glaucous below and sparsely bristly above. Leaves are ovate to broadly lanceolate and acute at the tip, with pustuliferous-based hairs on both lower and upper leaf surfaces. Plants produce from one to several flowering stalks which may be branched above. The inflorescence is a coiled cyme, up to 25 cm long in fruit, bearing 5-25 flowers. Sepals are sometimes unequal in width, some of them connate in pairs or triplets. The corolla is typically a broadly flaring funnel shape with blunt, ovate-rounded lobes and is burnt orange to deep yellow, with prominent deeper orange sinuses. The corolla limb is broad, its width approximately 0.5-0.9 times the length of the corolla tube. The tube is 10-nerved below the attachment of the stamens. Nutlets are shiny and smooth, 0.4-0.7 cm long, overall much longer than broad, lanceolate and trigonous with an elongate, acuminate tip, keel-like ventrally, less so dorsally.
