Quick facts for kidsClintonia umbellulata
Clintonia umbellulata, commonly known as white clintonia or speckled wood-lily, is a species of flowering plant in the lily family Liliaceae. The specific epithet umbellulata means "umbelled," which refers to the shape of the plant’s inflorescence.
Clintonia umbellulata is a perennial herbaceous plant that spreads by means of underground rhizomes. A plant stands 27 to 60 cm (11 to 24 in) tall with 2–4 dark green leaves, each 18 to 30 cm (7 to 12 in) long and 4.5 to 8 cm (2 to 3 in) wide. The inflorescence is a single terminal umbel with 10–25(–30) outward-facing flowers on a flowering stalk up to 50 cm (20 in) high. Each flower has six tepals and six stamens. The tepals are white or greenish white, often marked with purplish brown or green speckles, each tepal being 5.5 to 8 mm (0.2 to 0.3 in) long and 2.7 to 4 mm (0.1 to 0.2 in) wide. The stamens are 60% longer than the tepals. The fruits are black (occasionally ultramarine blue) berries, each 6 to 8 mm (0.2 to 0.3 in) long with 2–4 seeds per berry. Each seed is approximately 3.5 mm (0.1 in) long.
Because of their proximity, C. umbellulata and C. borealis are often confused. The following table compares the two species character by character (with diagnostic characters emphasized):
|C. umbellulata||C. borealis|
|Habitat||Hardwood forests less than 1,000 m (3,281 ft)||Mixed forests up to 1,600 m (5,249 ft)|
|Height||Plant stands 27 to 60 cm (11 to 24 in) tall||Plant stands 20 to 50 cm (8 to 20 in) tall|
|Leaves||Leaves 3–4, blade dark green, each leaf 18 to 30 cm (7 to 12 in) long and 4.5 to 8 cm (2 to 3 in) wide||Leaves 2–4, blade dark glossy green, each leaf 15 to 30 cm (6 to 12 in) long and 5 to 10 cm (2 to 4 in) wide|
|Flower buds||A tight cluster of spherical buds||A loose cluster of elongate buds|
|Inflorescence||Terminal umbel, 10–25(–30) outward-facing flowers||Terminal racemes, 3–8(–10) nodding flowers|
|Flowers||Tepals white or greenish white, often marked with purplish brown or green speckles, each tepal 5.5 to 8 mm (0.2 to 0.3 in) long and 2.7 to 4 mm (0.1 to 0.2 in) wide; filaments 5.5 to 7 mm (0.2 to 0.3 in) long; anthers approximately 4.5 mm (0.2 in) long||Tepals yellow or yellowish green, each tepal 12 to 16 mm (0.5 to 0.6 in) long and 3.5 to 4.5 mm (0.1 to 0.2 in) wide; filaments 12 to 17.5 mm (0.5 to 0.7 in) long; anthers approximately 3 mm (0.1 in) long|
|Fruits||Berries black (occasionally ultramarine blue), globose to ellipsoid, each berry 6 to 8 mm (0.2 to 0.3 in) long; seeds 2–4 per berry, each seed approximately 3.5 mm (0.1 in) long||Berries ultramarine blue (rarely white), ovoid, each berry 8 to 12 mm (0.3 to 0.5 in) long; seeds 8–16 per berry, each seed approximately 4 mm (0.2 in) long|
Based on morphological characters alone, bare-leaved Clintonia is generally difficult to identify, but flowering or fruiting plants are readily distinguishable.
C. umbellulata has numerous look-alikes. For example, the inflorescence of the small white leek (Allium tricoccum) is very similar in appearance. To distinguish the two, look at the leaves. The leaves of A. tricoccum have usually wilted by the time the plant is in full bloom while the leaves of C. umbellulata remain throughout the summer months.
In 1803, André Michaux described the species Convallaria umbellulata Michx., a name that was to become a synonym for Clintonia umbellulata (Michx.) Morong. The latter was first described by Thomas Morong in 1894.
In 1933, John Kunkel Small described the segregate species Xeniatrum umbellulatum, a distinction that did not persist. Numerous other synonyms are in use. Perhaps the best known is Clintonia alleghaniensis Harned, which unlike C. umbellulata has ultramarine blue (not black) fruit. It is known to occur at a number of sites in Virginia, Maryland, and West Virginia.

The range of C. umbellulata apparently overlaps with that of C. borealis throughout the Appalachian Mountains. (Counties where both species are known to occur are shown above in bold.) Actually C. umbellulata and C. borealis are allopatric, that is, the ranges of the two species do not significantly overlap but are immediately adjacent to one another.
C. umbellulata is globally secure, rare and imperiled in New York, and endangered in Ohio.
