Bulb of 2 scales, ca. 2 cm in diam. Stem 15--50 cm. Leaves rather densely arranged, basal 2 opposite, others in whorls of 4--7; leaf blade narrowly lanceolate to linear, 5--9 cm × 2--10 mm, apex strongly cirrose. Inflorescence 1--5-flowered; bracts 2 or 3, apex strongly cirrose. Flowers nodding, campanulate; pedicel 1--2 cm. Tepals white or pale yellow, occasionally tinged with pale purple, oblong-elliptic, 2--5 × 1.5--2 cm; nectaries ovate, projecting at a right angle abaxially. Stamens 1--2.5 cm; filaments dilated proximally, glabrous. Style 3-lobed, lobes 2--4 mm. Capsule winged; wings 2--4 mm wide. Fl. Apr--Jun, fr. Jul. 2 n = 24*.

Martyn Rix (pers. comm.) notes that Fritillaria verticillata commonly has an inflorescence with only one flower, and that reports of several-flowered plants are the result of longstanding confusion between this species and F. thunbergii. Rix also notes that F. albidoflora may be distinct from F. verticillata differing as follows: flowers opening nearly flat (vs. campanulate), tepals 2--3 cm (vs. 3--5 cm), and nectaries orbicular (vs. ovate), ca. 6 mm above base of tepal.
