There are at least 33 members of the heaths, wintergreens and monotropes order, Ericales, found in Montana. [1] Some of these species are exotics (not native to Montana) [2] and some species have been designated as Species of Concern. [3]
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.
Vaccinium is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other ericaceous plants, they are generally restricted to acidic soils.
A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead.
Bilberries or blueberries are a primarily Eurasian species of low-growing shrubs in the genus Vaccinium, bearing edible, dark blue berries. The species most often referred to is Vaccinium myrtillus L., but there are several other closely related species.
A calcifuge is a plant that does not tolerate alkaline (basic) soil. The word is derived from the Latin 'to flee from chalk'. These plants are also described as ericaceous, as the prototypical calcifuge is the genus Erica (heaths). It is not the presence of carbonate or hydroxide ions per se that these plants cannot tolerate, but the fact that under alkaline conditions, iron becomes less soluble. Consequently, calcifuges grown on alkaline soils often develop the symptoms of iron deficiency, i.e. interveinal chlorosis of new growth. There are many horticultural plants which are calcifuges, most of which require an 'ericaceous' compost with a low pH, composed principally of Sphagnum moss peat. Alternatively sulphur chips may be used to lower soil pH.
The Northern California coastal forests are a temperate coniferous forests ecoregion of coastal Northern California and southwestern Oregon.
Wintergreen is a group of aromatic plants, many in the genus Gaultheria.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains, including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains. It covers an area of about 61,500 square miles (159,000 km2) in: northeast Alabama and Georgia, northwest South Carolina, eastern Tennessee, western North Carolina, Virginia, Maryland, and central West Virginia and Pennsylvania; and small extensions into Kentucky, New Jersey, and New York.
An oak–heath forest is a plant community association and type of forest ecology. It is a deciduous forest type of well-drained, acidic soils, characterized by oaks (Quercus) and plants of the heath family (Ericaceae). It is commonly found in the high elevations of the eastern United States. Such forest areas typically have a dense fibrous root layer at the surface of the soil, and in many areas predominate on south-facing or southwest-facing slopes. Many of the existing oak–heath forests once featured American chestnut as an important canopy species.
Huckleberry is a name used in North America for several plants in the family Ericaceae, in two closely related genera: Vaccinium and Gaylussacia.
Vaccinium membranaceum is a species within the group of Vaccinium commonly referred to as huckleberry. This particular species is known by the common names thinleaf huckleberry, tall huckleberry, big huckleberry, mountain huckleberry, square-twig blueberry, and (ambiguously) as "black huckleberry".
Geocaulon is a monotypic genus of flowering plants in the family Santalaceae containing the single species Geocaulon lividum, which is known by the common names northern comandra and false toadflax. It is native to northern North America, where it is common and widespread from Alaska to Newfoundland and into the northernmost contiguous United States.
Gaylussacia frondosa is a species of flowering plant in the heath family known by the common names dangleberry and blue huckleberry. It is native to the eastern United States, where it occurs from New Hampshire to South Carolina.
Vaccinium myrsinites is a species of flowering plant in the heath family known by the common name shiny blueberry. It is native to the southeastern United States from Alabama, Georgia, South Carolina and Florida. It may occur as far west as Louisiana.
