Maianthemum trifolium (Three-leaf Solomon's-seal, three-leaf Solomon's-plume, threeleaf false lily of the valley, smilacine trifoliée) 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). [2]
It is a herbaceous perennial plant growing erect, 10–25 cm (4–10 in) tall. It grows off spreading sympodial rhizomes with roots found only at nodes. New plants produce two petiolate foliage leaves the first year, [3] then a flowering shoot the second year with 2-4 sessile leaves.
Fertile plants have 2-4 alternate leaves that are elliptic, 5–12 cm (1.97–4.72 in) long and 2.5–4 cm (1–1+1⁄2 in) broad. [2] Leaf bases are narrowly tapered and tips pointed.
5 to 15 flowers are produced on a simple raceme 5–10 cm (2–4 in) long. There is only one flower per node, set on a 1–3 mm (0.04–0.12 in) long pedicel.
Flowers are trimerous, that is, flower parts are in groups of three. Each flower has 6 white tepals 2–4 mm (0.08–0.16 in) long. Fruits are berries 4–6 mm (0.16–0.24 in) wide, mottled with fine red spots when young, maturing to red. Berries contain 1-3 small, rounded seeds. Flowering is May to June, berries remain on plants into September. [2]
Found in all Canadian provinces and territories and in the USA in some northeastern states (Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, and Wisconsin). Also found in St. Pierre and Miquelon and Asia (Siberia). [2]
Maianthemum trifolium often forms dense patches in wet forests, sphagnum bogs and other wetlands and is sometimes considered to be aquatic. [2]
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 canadense 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. 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 2-3 leaves. Flowering shoots have clusters of 12–25 starry-shaped, white flowers held above the leaves.
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 bifolium is often a localized common rhizomatous flowering plant, native from western Europe east to Siberia, China and Japan.
Streptopus amplexifolius is a species of flowering plant in the family Liliaceae, native to North America, Europe and Asia.
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 from 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.
Streptopus lanceolatus, is an understory perennial plant native to the forests of North America, from Alaska to Labrador, south through the Great Lakes and Appalachian Mountain regions of the United States, as well as Montana, Washington state, Oregon, and St. Pierre & Miquelon. It grows primarily in mixed-wood forests, and throughout a wide range of soil and site conditions, preferring cool, acidic soils.
Acrothamnus hookeri, commonly known as the mountain beardheath, is a flowering plant in the family Ericaceae and grows in subalpine regions of southeastern Australia. It is a small upright shrub with oblong-shaped leaves and white flowers.
Maianthemum paniculatum is a perennial flowering plant; a species of monocot found from Mexico to Panama. It is often associated with montane environments and is found primarily in forest openings and along roadsides.
Hypericum undulatum, the wavy St Johns Wort, is a herbaceous perennial flowering plant native to western Europe and northern Africa. The specific name undulatum is Latin, meaning "wavy" or "undulated", referring, just as the common name, to the wavy leaf margins of the herb. The plant has a diploid number of 16 or 32.
Maianthemum amoenum is a perennial flowering plant, growing as an epiphyte on trees in cloud forests from Mexico south to Honduras.
