Gentiana autumnalis subsp. pennelliana is a perennial herb, which grows at approximately 20 cm (7.9 in) in height. The leaves are linear elliptic, 3–4 cm (1.2–1.6 in) long and widely spaced along the stem. The distinctive white tubular flowers, which are sometimes fringed with purple, are solitary and terminal, with a 7 cm (2.8 in) long flare at the opening with five entire lobes, alternating with five shorter fringed membranes.
