Perennial herb with a elongate, slender rhizome stem 10 - 45 cm tall Stem: one, one-branched, upright, forked above the middle, with sheathing bracts at the base. Leaves: alternate, stalkless, 4 - 6.5 cm long, 1.5 - 3 cm wide, oblong lance-shaped to elliptic with a pointed tip, minutely toothed, with a waxy coating (glaucous) on the lower surface. One or two leaves grow beneath the fork of the stem. Flowers: one per stem, terminal (but appearing axillary), nodding, pale straw-yellow, narrowly bell-shaped, with six distinct tepals. Tepals over-lapping, 1.2 - 2.5 cm long, 2 - 4.5 mm wide, elongate, with a pointed tip. Flower stalk 0.6 - 1.6 cm long. Stamens six, 8 - 15 mm long. Fruit: a sharply three-winged capsule, distinctly stalked, greenish to yellowish brown, 1.5 - 3 cm long, 1 - 1.6 cm wide, ellipsoid. Seeds brownish red, nearly spherical.
Similar species: The similar Uvularia grandiflora and U. perfoliata differ by having perfoliate leaves.
Flowering: April to June
Habitat and ecology: Rare in the Chicago Region. A substantial population was discovered in Porter County, Indiana growing in full sun between thickets in a cutover area. Typically found in rich woods.
Occurence in the Chicago region: native
Etymology: Uvularia comes from the word uvula (the soft lobe that dangles at the back of the throat) of which the drooping flowers resemble. Sessilifolia means stalkless.

Colonies are infrequently found in the southern counties where it grows in hard, clay soil, usually associated with beech, beech and sweet gum, and lowland oaks. It propagates mostly from the rootstocks and a note on one of my labels reads: "I found, in a low woods about 3 miles southwest of Dale, Spencer County, two colonies about 10 X 20 feet and this species formed a mat over these areas."
