Maianthemum canadense (Canadian may-lily, Canada mayflower, false lily-of-the-valley, Canadian lily-of-the-valley, wild lily-of-the-valley, [3] two-leaved Solomon's seal) [4] is an understory perennial flowering plant, native to Canada and the northeastern United States, from Yukon and British Columbia east to Newfoundland, into St. Pierre and Miquelon. [4] It can be found growing in both coniferous and deciduous forests. The plant appears in two forms, either as a single leaf rising from the ground with no fruiting structures or as a flowering/fruiting stem with two to three leaves. Flowering shoots have clusters of 12–25 starry-shaped, white flowers held above the leaves. [4]
The plant is rich in calcium and phosphorus and as such makes up the bulk of the diet of white-tailed deer in the northeastern United States in the spring, when lactating does and antler-growing bucks require extra amounts of those nutrients. [5]
Plants grow to 10–25 cm (4–10 in) tall, [6] arising from branching rhizomes that have roots only at the nodes. Plants may be one-leaved and without fruiting structures (sterile). the fertile, flowering shoots have 2–3 leaves.
The leaf blades are 4.5–9 cm (2–4 in) long by 3–5.5 cm (1–2 in) wide with a pointed tip. The lowest leaves are usually egg-shaped with two lobes at the base and a narrow space (sinus) between the lobes. Upper leaves are usually heart-shaped and set on a short 1–7 mm long petiole.
The clusters of 12–25 starry-shaped, white flowers are set in a complex raceme - an unbranched flowering cluster that has 1-3 (usually 2) stalked flowers per node, set at roughly equal distances along a central axis. The lowest flowers open first. The flower stalks (pedicels) are 3–7 mm long and thin (0.2-0.5 mm wide). [7]
The flowers are produced from spring to mid summer. They have four conspicuous, white, 1.5–2 mm long tepals. The fruit is a berry containing one or two round seeds. The berries are 4–6 mm across, mottled red in early summer and turning deep red by mid summer. A seed is produced infrequently and most plants in a location are vegetative clones, spreading by their shallow, trailing, white rhizomes.
It is found in Canada from southeastern Yukon, southern Northwest Territories, into eastern British Columbia and east to Newfoundland and Labrador, and into St. Pierre and Miquelon. It is also found in the northern United States from the Dakotas east, south along the Appalachian Mountains and disjunct populations in Colorado, Wyoming, Nebraska and Kansas. [4] It is possibly extirpated from Montana.
Primarily a boreal forest understory species, but also found at low elevation sites in the Rocky Mountains, to 1800 m. [4] It is associated with moist woods but is also found in sandy pine woods in the north [8] and can persist in clearings. [4]
Although most Maianthemum have flower parts in sets of three, M. canadense plants have flowers with four tepals and four stamens, as in the very closely related Maianthemum bifolium and Maianthemum dilatatum . The range of these species do not overlap. M. bifolium is found in temperate Eurasia, [9] and M. dilatatum is essentially a coastal species found from Alaska south to northwest California as well as Mongolia to Japan. [10] Maianthemum trifolium is also a small herb and has a distribution similar to M. canadense, but the flower parts are in sets of 3s, the leaf bases are tapered, not heart-shaped; it is found in wet habitat such as bogs. [4]
No subspecies are currently recognized, although in the western half of the range plants with hairs and consistently larger leaves have been treated as var. interius. [4]
Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.
Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.
Maianthemum dilatatum is a common rhizomatous perennial flowering plant that is native to western North America from northern California to the Aleutian islands, and Asia across the Kamchatka Peninsula, Japan, and Korea. It grows in coastal temperate rainforests, and is often the dominant groundcover plant in Sitka Spruce forests.
Maianthemum racemosum, the treacleberry, feathery false lily of the valley, false Solomon's seal, Solomon's plume or false spikenard, is a species of flowering plant native to North America. It is a common, widespread plant with numerous common names and synonyms, known from every US state except Hawaii, and from every Canadian province and territory, as well as from Mexico.
Maianthemum trifolium is a species of flowering plant that is associated with extremely wet environments and is native to Canada and the northeastern United States as well as St. Pierre and Miquelon and Asia (Siberia).
Maianthemum bifolium is often a localized common rhizomatous flowering plant, native from western Europe east to Siberia, China and Japan.
Maianthemum stellatum is a species of flowering plant, native across North America. It has been found in northern Mexico, every Canadian province and territory except Nunavut, and every US state except Hawaii and the states of the Southeast. It has little white buds in the spring, followed by delicate starry flowers, then green-and-black striped berries, and finally deep red berries in the fall.
