Penstemon floridus is a species of penstemon known by the common name Panamint beardtongue. It is native to the lower mountain and plateau areas of eastern California and western Nevada, where it grows in canyons, arroyos, and sagebrush scrub. It is a perennial herb producing erect stems sometimes exceeding one meter tall. The thick leaves are lance-shaped to oval, usually toothed and somewhat wavy, and arranged in pairs with bases clasping the stem. The hairy flower cluster produces showy flowers up to 3 centimeters long and tubular in shape with a wide throat becoming narrowed at the lipped mouth. The flowers are bright pink with darker lining inside. There are two varieties of this species. Austin's beardtongue, var. austinii, is named for Stafford Wallace Austin, collector of plants and husband of writer Mary Hunter Austin.
