Oxalis Montana
''Oxalis montana'' is a species of flowering plant in the family Oxalidaceae known by the common names mountain woodsorrel, wood shamrock, sours and white woodsorrel. It may also be called common woodsorrel, though this name also applies to its close relative, ''Oxalis acetosella''. This species is a perennial herb native to eastern North America, including eastern Canada and the north-central and eastern United States, and Appalachian Mountains.Pavek, Diane S.

Oxalidaceae
The Oxalidaceae, or wood sorrel family, are a small family of five genera of herbaceous plants, shrubs and small trees, with the great majority of the 570 species in the genus ''Oxalis'' (wood sorrels). Members of this family typically have divided leaf, leaves, the leaflets showing "sleep movements", spreading open in light and closing in darkness. The genus ''Averrhoa'' of which starfruit is a member, is usually included in this family (e.g. APG IV, 2016), but some botanists place it in a separate family, Averrhoaceae.

Understory
In forestry and ecology, understory (American English), or understorey (English in the Commonwealth of Nations, Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the Canopy (biology), forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy, so understory vegetation is generally Shade tolerance, shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines, and undergrowth. Small trees such as holly and Cornus (genus), dogwood are understory specialists. In Temperate broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Trientalis Borealis
''Lysimachia borealis'' (synonym ''Trientalis borealis''), the starflower, is a North American woodland perennial that blooms between May and June. Description Starflowers have creeping rhizomes with vertical stalks. Each stalk has a whorl of 5–10 lanceolate leaves (up to long) at its tip, with one to four (most often one or two) white flowers on smaller stalks extending from the center of the whorl. The flowers are about across and consist of five to nine petals that form a star-like shape. Its fruit is tiny, globe-shaped, pale blue, and matte. Biology ''Lysimachia borealis'' has three, fairly discrete phases of the life cycle each year: shoot development, rhizome growth, and tuber formation. The species reproduces both sexually, by seed, and asexually, via tubers. Flowers are pollinated primarily by halictid and andrenid bees. In response to warming, ''L. borealis'' appears to shift reproductive effort away from sexual reproduction toward asexual vegetative spread. The ...

Coptis Groenlandica
''Coptis trifolia'', commonly known as the threeleaf goldthread or savoyane, is a perennial plant in the genus ''Coptis'', a member of the family Ranunculaceae. Distribution It is native to North America and Asia across the subarctic region. Its range is divided into three broad groups. The first is from southern Greenland and Labrador that extends to Manitoba to the west and to the mountains of North Carolina to the south. The second is in Alaska and adjacent areas of British Columbia, extending towards eastern Siberia and into Japan and Manchuria. Records from Norway and central Russia are most likely based on confusion. The disrupted and wide range of the species suggests that the three populations have been isolated from each other for significant periods of time. Goldthread seems to prefer coniferous or mixed canopies dominated by Eastern hemlock, but it has also been found in deciduous canopies in moist, acidic soils. Description Goldthread has at least one small, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Maianthemum Canadense
''Maianthemum canadense'' (Canadian may-lily, Canada mayflower, false lily-of-the-valley, Canadian lily-of-the-valley, wild lily-of-the-valley,, p.105 two-leaved Solomon's seal) 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 two to three leaves. Flowering shoots have clusters of 12–25 starry-shaped, white flowers held above the leaves. 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.

Fagus Grandifolia
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around the bottom ...

Betula Lutea
''Betula alleghaniensis'', the yellow birch, golden birch, or swamp birch, is a large tree and an important lumber species of birch native to northeastern North America. Its vernacular names refer to the golden color of the tree's bark. In the past its scientific name was ''Betula lutea'', the yellow birch. ''Betula alleghaniensis'' is the provincial tree of Quebec, where it is commonly called ''merisier'', a name which in France is used for the wild cherry. Description ''Betula alleghaniensis'' is a medium-sized, typically single-stemmed, deciduous tree reaching tall (exceptionally to ) with a trunk typically in diameter, making it the largest North American species of birch. Yellow birch is long-lived, typically 150 years and some old growth forest specimens may last for 300 years. It mostly reproduces by seed. Mature trees typically start producing seeds at about 40 years but may start as young as 20. The optimum age for seed production is about 70 years. Good seed crop ...

Acer Saccharum
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and the eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be called "rock maple," "sugar tree," "sweet maple," or, particularly in reference to the wood, "hard maple," "Bird's eye figure, birds-eye maple," or "curly maple," the last two being specially Figure (wood), figured lumber. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaf, leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes a ...

Acer Rubrum
''Acer rubrum'', the red maple, also known as swamp maple, water maple, or soft maple, is one of the most common and widespread deciduous trees of eastern and central North America. The U.S. Forest Service recognizes it as the most abundant native tree in eastern North America. The red maple ranges from southeastern Manitoba around the Lake of the Woods on the border with Ontario and Minnesota, east to Newfoundland, south to Florida, and southwest to East Texas. Many of its features, especially its leaves, are quite variable in form. At maturity, it often attains a height around . Its flowers, petioles, twigs, and seeds are all red to varying degrees. Among these features, however, it is best known for its brilliant deep scarlet foliage in autumn. Over most of its range, red maple is adaptable to a very wide range of site conditions, perhaps more so than any other tree in eastern North America. It can be found growing in swamps, on poor, dry soils, and almost anywhere in between. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ecotone
An ecotone is a transitional area between two plant communities, where these meet and integrate. Examples include areas between grassland and forest, estuaries and lagoon, freshwater and sea water etc. An ecotone may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined (and its etymology given) in 1904 in "The Development and Structure of Vegetation" (Lincoln, Nebraska: Botanical Seminar) by Frederic E. Clements. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, wi ...

Northern Hardwood Forest
The northern hardwood forest is a general type of North American forest ecosystem found over much of southeastern and south-central Canada, Ontario, and Quebec, extending south into the United States in northern New England, New York, and Pennsylvania, and west along the Great Lakes to Minnesota and western Ontario. Some ecologists consider it a transitional forest because it contains species common to both the oak-hickory forest community to the south and the Boreal forest community to the north. The trees and shrub species of the Northern Hardwood Forest are known for their brilliant fall colors, making the regions that contain this forest type popular fall foliage tourist destinations. Sugar maple, yellow birch, American beech, and white ash are the common key indicator tree and shrub species in the Northern Hardwood Forest. Other species include eastern hemlock and eastern white pine. Herb and heath species include wintergreen, wild sarsaparilla, and wood sorrel. Bir ...
