State Rank Reason (see State Rank above)
Tellima grandiflora occurs in northwestern Montana. Plants grow in mesic coniferous forests from low to high elevations and often near streams. Populations are typically small and localized, though some sites are known to support several hundred plants. Populations are also frequently found near established game or hiking trails. While plants may be uncommon its habitat appears to be widespread and relatively secure, and threats have not been identified. Current data on population sizes, viability, habitat condition, and threats is needed.

General Description
PLANTS: Perennial forbs from a horizontal rootstock. Stems are erect, hirsute below, glandular above, and 40–70 cm tall. Source: Lesica et al. 2012.

LEAVES: Basal and alternately arranged on the stem, and sparsely hairy. Lower leaves have petioles and blades that are cordate-orbicular in shape, 5- to 7-lobed with dentate margins, and 3–12 cm wide. Upper leaves are smaller and sessile (lack petioles). Source: Lesica et al. 2012.

INFLORESCENCE: A narrow, glandular raceme. Flowers are 5-merous, regular, and perfect. Calyx is cup-shaped, 6–8 mm long, and has erect lobes. Petals are white to reddish, 4–6 mm long with 5 to 7 thread-like lobes at the tip. Stamens are 10. Pistil is inferior, but less than half of it is fused with the hypanthium. Fruit is a capsule. Capsule is 6–8 mm long with numerous seeds. Source: Lesica et al. 2012.

Range Comments
Alaska south to California, Oregon, Idaho, and Montana (Lesica et al. 2012). In Montana plants have been found in Flathead and Lincoln counties (Lesica et al. 2012).
