Oreojuncus Trifidus
''Oreojuncus trifidus'' is a species of rush known by the common names highland rush and three-leaved rush. It is native to the Northern Hemisphere, where it is an arctic/montane species with an amphi-atlantic distribution. Description ''Oreojuncus trifidus'' is a perennial herb with tufted stems up to 40 centimeters long, growing erect or drooping. There are a few grasslike leaf blades measuring up to 12 centimeters long. The inflorescence holds one to four flowers with brown tepals and six stamens. The fruit is a capsule a few millimeters long.''Juncus trifidus''. Flora of North America. The plant reproduces sexually with its flowering structures and |
Juncaceae
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is ''Juncus''. Most of the ''Juncus'' species grow exclusively in wetland habitats. A few rushes, such as ''Juncus bufonius'' are annuals, but most are perennials. Description The leaves are evergreen and well-developed in a basal aggregation on an erect stem. They are alternate and tristichous (i.e., with three rows of leaves up the stem, each row of leaves arising one-third of the way around the stem from the previous leaf). Only in the genus '' Distichia'' are the leaves distichous. The rushes of the genus ''Juncus'' have flat, hairless leaves or cylindrical leaves. The leaves of the wood-rushes of the genus ''Luzula' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poales Genera
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus ''Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG III system (2009) accepts the order within a monocot clade called commelinids, and accepts the following 16 families: The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; rec ...
