Pinus Contorta
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine zone, subalpine, but is rare in lowland temperate rainforest, rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The Crown (botany), crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches a ...

Pinus Banksiana
Jack pine (''Pinus banksiana'') is an eastern North American pine. Its native range in Canada is east of the Rocky Mountains from the Mackenzie River in the Northwest Territories to Cape Breton Island in Nova Scotia, and the north-central and northeast of the United States from Minnesota to Maine, with the southernmost part of the range just into northwest Indiana and northwest Pennsylvania. It is also known as grey pine and scrub pine. In the far west of its range, ''Pinus banksiana'' hybridizes readily with the closely related lodgepole pine (''Pinus contorta''). The species epithet ''banksiana'' is after the English botanist Sir Joseph Banks. Description ''Pinus banksiana'' ranges from in height. Some jack pines are shrub-sized, due to poor growing conditions. They do not usually grow perfectly straight, resulting in an irregular shape similar to pitch pine (''Pinus rigida''). This pine often forms pure stands on sandy or rocky soil. It is fire-adapted to stand-rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca Altaica
''Festuca altaica'', synonym ''Festuca scabrella'', is a perennial bunchgrass with a wide native distribution in the Arctic, from central Asia to eastern North America. It has been called altai fescue and, under the synonym ''F. scabrella'', rough fescue. Description ''Festuca altaica'' is a densely tufted perennial grass. The tufts are connected by short rhizomes. The flowering stems ( culms) are usually tall, but may reach . The upper (adaxial) surface of the leaves is densely covered with short hairs. A ligule is present and is long. The inflorescence is a loose panicle. The spikelets are long, purple to brown in color, and have 3 to 6 individual florets. ''Festuca altaica'' flowers and fruits from late spring to the fall. Taxonomy ''Festuca altaica'' was first described in 1829 by Carl Bernhard von Trinius, who wrote the section on grasses in ''Flora Altaica'', whose principal author was Carl Friedrich von Ledebour.

Calamagrostis Canadensis
''Calamagrostis canadensis'' is a species of grass, having three or more varieties, in the family Poaceae. It is known variously by the common names of bluejoint, bluejoint reedgrass, marsh reedgrass, Canadian reedgrass, meadow pinegrass, and marsh pinegrass. Varieties ''Calamagrostis canadensis'' takes the form of at least three varieties, including the type. The U.S. Forest Service names others. * The type variety (and autonym), is ''C. c.'' var. ''canadensis''. This is the name for ''C. canadensis'' after varieties of it were named, and is used only to differentiate it from the other, newer varieties. The common name is bluejoint * ''C. c.'' var. ''langsdorffii''. It is also called bluejoint. * ''C. c.'' var. ''macouniana''. It is known as Macoun's reedgrass.

Shepherdia Canadensis
''Shepherdia canadensis'', commonly called Canada buffaloberry, russet buffaloberry, soopolallie, soapberry, or foamberry (Ktunaxa: ',) is one of a small number of shrubs of the genus ''Shepherdia'' that bears edible berries. Description The plant is a deciduous shrub of open woodlands and thickets, growing to a maximum of . The fruit is usually red, but one variety has yellow berries. The berries have a bitter taste. It is a non-legume nitrogen fixer. Etymology The common name of the plant in British Columbia is "soopolallie", a word derived from the historic Chinook Jargon trading language spoken in the North American Pacific Northwest in the 19th and early 20th centuries. The name is a composite of the Chinook words "soop" (soap) and "olallie" (berry).Turner, Nancy J., Laurence C. Thompson, M. Terry Thompson, and Annie Z. York. 1990. Thompson Ethnobotany.

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the 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-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 dogwood are understory specialists. In 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 potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Dominance (ecology)
Ecological dominance is the degree to which one or several species have a major influence controlling the other species in their ecological community (because of their large size, population, productivity, or related factors) or make up more of the biomass. Most ecological communities are defined by their dominant species. *In many examples of wet woodland in western Europe, the dominant tree is alder ('' Alnus glutinosa''). *In temperate bogs, the dominant vegetation is usually species of ''Sphagnum'' moss. *Tidal swamps in the tropics are usually dominated by species of mangrove (''Rhizophoraceae'') *Some sea floor communities are dominated by brittle stars. *Exposed rocky shorelines are dominated by sessile organisms such as barnacles and limpets. See also * National Vegetation Classification, a system for classifying British British may refer to: Peoples, culture, and language * British people, nationals or natives of the United Kingdom, British Overseas Territori ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
