Isoetes, commonly known as the quillworts, is a genus of lycopod. It is the only living genus in the family Isoetaceae and order Isoetales. There are currently 192 recognized species, with a cosmopolitan distribution mostly in aquatic habitats but with the individual species often scarce to rare. Some botanists split the genus, separating two South American species into the genus Stylites, although molecular data place these species among other species of Isoetes, so that Stylites does not warrant taxonomic recognition. Species virtually identical to modern quillworts have existed since the Jurassic epoch, though the timing of the origin of modern Isoetes is subject to considerable uncertainty.
Erica arborea, the tree heath or tree heather, is a species of flowering plant (angiosperms) in the heather family Ericaceae, native to the Mediterranean Basin and Ethiopia, Kenya and Tanzania in East Africa. It is also cultivated as an ornamental.
The third generation of the BMW 3 Series range of compact executive cars is designated under the model code E36, and was produced by the German automaker BMW from 1990 to 2000. The initial models were of the four-door sedan body style, followed by the coupe, convertible, wagon ("Touring"), hatchback ("Compact"), and the rare four-door convertible Baur TC4 in later years.
Isoetes lacustris, the lake quillwort or Merlin's grass, is a boreal quillwort native on both sides of the northern Atlantic Ocean. Synonyms include Isoetes hieroglyphica.
Alpina Burkard Bovensiepen GmbH & Co. KG is an automobile manufacturing company based in Buchloe, in the Ostallgäu district of Bavaria, Germany that develops and sells high-performance versions of BMW cars. Alpina works closely with BMW and their processes are integrated into BMW's production lines, and is recognized by the German Ministry of Transport as an automobile manufacturer, in contrast to other performance specialists, which are aftermarket tuners. The Alpina B7 is produced at the same assembly line in Dingolfing, Germany, as BMW's own 7 Series. The B7's twin-turbo 4.4-litre V8 is assembled by hand at Alpina's facility in Buchloe, Germany, before being shipped to BMW for installation, and the assembled vehicle is then sent back to Alpina for finishing touches.
The Australian flowering shrub Grevillea alpina has several common names, including mountain grevillea, alpine grevillea, and cat's claws. It is not limited to alpine environments, and in fact is less common at high elevation than low. The species is variable in appearance, with five general forms described: small-flowered, Grampians, Northern Victorian, Goldfields, and Southern Hills forms. It is found in dry forests and woodlands across Victoria and into southern New South Wales. Some forms of the plant are low to the ground, and some become a spreading shrub. The flowers come in many colours, from white to green to shades of red and pink, or a pattern of several colours. The curled flowers are 1 to 3 centimetres in length. It is attractive to nectar-feeding insects and birds.
Lobelia dortmanna, Dortmann's cardinalflower or water lobelia, is a species of flowering plant in the bellflower family Campanulaceae. This stoloniferous herbaceous perennial aquatic plant with basal leaf-rosettes and flower stalks grows to 0.7–2 m (2.3–6.6 ft) tall. The flowers are 1–2 cm long, with a five-lobed white to pale pink or pale blue corolla, produced in groups of one to ten on an erect raceme held above the water surface. The fruit is a capsule 5–10 mm long and 3–5 mm wide, containing numerous small seeds.
Isoetes sinensis, the narrow quillwort, is a species of plant in the family Isoetaceae.
Isoetes engelmannii is a species of aquatic plant in the family Isoetaceae. It is referred to by the common names Engelmann's quillwort or Appalachian quillwort, and is the most widely distributed species of its genus in eastern North America. Its range extends from Ontario in the north, south to Florida and west Arkansas and Missouri. It can be found from April to October in temporary pools, bogs, marshes, stream edges, swamps and along wet roadsides.
Isoetes valida, commonly known as the strong quillwort or true quillwort, is an aquatic lycophyte native to eastern North America. It is found primarily in the Appalachian Mountains from Pennsylvania south to Alabama and Georgia. In addition, one collection of the plant was made in a railway ditch in Wilmington, Delaware in the 1860s, but this was most likely an accidental introduction.
Astelia is a genus of flowering plants in the recently named family Asteliaceae. They are rhizomatous tufted perennials native to various islands in the Pacific, Indian, and South Atlantic Oceans, as well as to Australia and to the southernmost tip of South America. A significant number of the known species are endemic to New Zealand. The species generally grow in forests, swamps and amongst low alpine vegetation; occasionally they are epiphytic.
Isoetes eludens is an aquatic plant in the genus commonly known as quillwort that is native to the Kamiesberg Mountains in Namaqualand, South Africa. So far it is known to grow only in a single !gau (gnamma), a small temporary pool formed in a hollowed out area of granite rock. It has likely been growing in that region for millions of years, but was only discovered in 2007 and described in 2009. The specific epithet eludens refers to the fact that it eluded discovery, in spite of several searches in recent years in the area for new quillwort species.
Gleichenia alpina, commonly known as alpine coral-fern, is a small fern species that occurs in Tasmania and New Zealand. It grows in alpine and subalpine areas with moist soils and is a part of the Gleichrniaceae family.
Caladenia alpina, commonly known as the mountain caladenia, is a species of plant in the orchid family Orchidaceae and is native to subalpine areas of south-eastern Australia and to New Zealand. It has a single fleshy leaf and a thin wiry flowering spike bearing two white flowers with red bars on the labellum. In New Zealand this orchid is sometimes known as Caladenia lyallii.
Isoetes echinospora, also known as spiny quillwort, spiny-spored quillwort or spring quillwort is a species of quillwort in the Isoetaceae family, and is the most abundant species in Canada. It can be found in shallow aquatic environments from Labrador and Newfoundland to Alaska, and south to Pennsylvania, Wisconsin, Michigan, Colorado, and California. In Germany it is found in only two locations: the Feldsee and Lake Titisee, both in the High Black Forest.
Isoetes acadiensis, the Acadian quillwort is a species of quillwort in the Isoetaceae family described by Kott in 1981. It can be found along the shores of lakes, ponds, and rivers in Newfoundland, Nova Scotia, and New Brunswick, as well as in the American states Maine, Massachusetts, and New Hampshire. It has a similar distribution to that of I. tuckermanii. It bears 9 to 35 mostly recurved leaves, each 5–21 cm long. The leaves are usually dark green, though can occasionally be tinged with red. The sporangium can be up to five millimeters long and 3 millimeters in length, covered one sixth to one third by the velum. The spherical megaspores are 400-570 micrometers in diameter, and bear smooth ridges. The kidney shaped microspores are 25 to 30 micrometers long. It was originally believed to be a member of Isoetes hieroglyphica because of their similar megaspore structure.
Isoetes tuckermanii, or Tuckerman's quillwort, is a tetraploid species of plant in the family Isoetaceae. It can be found in shallow water in Newfoundland, Nova Scotia, New Brunswick, and south through the New England states to Maryland. It bears 10 to 45 long bright green to yellow green leaves that are 4 to 25 centimeters long, usually erect, but sometimes recurved. The velum covers one fourth or less of the sporangium, which is usually unspotted, 5 millimeters long, and 3 millimeters wide. The white spherical megaspores are 400 to 650 micrometers in diameter, and bear rough-crested ridges that form a hexagonal honeycomb shape. The kidney shaped microspores are 24 to 33 micrometers long, bearing tubercles. It is very similar to I. macrospora, only reliably distinguishable by cytology or through careful megaspore measurement.
Astelia alpina called pineapple grass, silver astelia, or perching lily is a commonly found species in alpine and subalpine areas of Tasmania and the Australian Alps. It is a perennial herb that typically dominates its environment by growing in dense clusters, called mats, in alpine bogs. There are two subspecies: Astelia alpina var. novae hollandiae from New South Wales and Victoria and Astelia alpina var. alpina endemic to Tasmania. Both subspecies appear very similar to each other. The species was originally described by Robert Brown.
Isoetes butleri, commonly known as limestone quillwort, is a species of plant in the quillwort family, a member of the lycophytes.
