Carex Bicolor
''Carex bicolor'', the bicoloured sedge, is a species of sedge native to North America, Northern Europe and Northern Asia. The International Union for Conservation of Nature has assessed the plant's conservation status as being of least concern because it has a widespread distribution and faces no particular threats. Description ''Carex bicolor'' is a tufted perennial sedge growing to a height of about . The grass-like leaves are mostly basal, greyish-green with blades up to long and wide, linear, strongly keeled, with parallel veins and long pointed tips. The inflorescence has a triangular stem about the same length as the leaves. It bears two or three spikes of small flowers, the terminal spike having staminate flowers for the lowest third and pistillate flowers above. The floral scale is shorter than the perigynium that surrounds the achene and has brown or reddish-black edges with a green midvein. Distribution and habitat ''Carex bicolor'' has a pan-boreal distribution. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperaceae
The Cyperaceae () are a family of graminoid (grass-like), monocotyledonous flowering plants known as wikt:sedge, sedges. The family (biology), family is large; botanists have species description, described some 5,500 known species in about 90 genus, generathe largest being the "true wikt:sedge, sedges" (genus ''Carex''), with over 2,000 species. Distribution Cyperaceae species are widely distributed with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges grow in almost all environments, many thrive in wetlands or in poor soils. Community (ecology), Ecological communities dominated by sedges are known as s or as sedge meadows. Classification Some species superficially resemble the closely related Juncaceae , rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example be ...

Inner Hebrides
The Inner Hebrides ( ; ) is an archipelago off the west coast of mainland Scotland, to the south east of the Outer Hebrides. Together these two island chains form the Hebrides, which experience a mild oceanic climate. The Inner Hebrides comprise 35 inhabited islands as well as 44 uninhabited islands with an area greater than . Skye, Isle of Mull, Mull, and Islay are the three largest, and also have the highest populations. The main commercial activities are tourism, crofting, fishing and Scotch whisky, whisky distilling. In modern times the Inner Hebrides have formed part of two separate local government jurisdictions, one to the north and the other to the south. Together, the islands have an area of about , and had a population of 18,948 in 2011. The population density is therefore about . There are various important prehistoric structures, many of which pre-date the first written references to the islands by Classical antiquity, Roman and Greek authors. In the historic period ...

Flora Of Northern America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Rùm
Rùm (), a Scottish Gaelic language, Scottish Gaelic name often Anglicisation, anglicised to Rum ( ), is one of the Small Isles of the Inner Hebrides, off the west coast of Scotland, in the district of Lochaber.
