Elodea canadensis is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
Maianthemum trifolium is a species of flowering plant that is associated with extremely wet environments and is native to Canada and the northeastern United States as well as St. Pierre and Miquelon and Asia (Siberia).
Sagina subulata (, the heath pearlwort, Irish-moss, awl-leaf pearlwort or Scottish moss, is a species of flowering plant in the pink and carnation family Caryophyllaceae. It is native to Europe, from Iceland south to Spain, and east to southern Sweden and Romania. It occurs on dry sandy or gravelly soils.
Adenocaulon bicolor, the American trailplant, trailplant, pathfinder, or silver-green, is a flowering plant in the family Asteraceae, native to North America. It is found in southern Canada and across the northern and western United States. It is the only species of Adenocaulon native to the United States or Canada. The genus name Adenocaulon is derived from Greek, and refers to the glandular stem. The English name "Pathfinder" was given to this species, because if you walk through a patch of its leaves you will find the path you made through them, with some of the white undersides of the leaves having been exposed, by them having been twisted. Over time, the plant will turn its leaves back with the green side up, and the white side down.
Frankenia pauciflora, the common sea-heath or southern sea-heath, is an evergreen shrub native to southern Australia. It is part of the Frankenia genus of the Frankeniaceae family.
Juncus scheuchzerioides is a species of rush variously called short rush or greater rush. It has an Antarctic circumpolar distribution and is native to many subantarctic islands in, and on the regions bordering, the Southern Ocean.
Colobanthus kerguelensis is a low-growing, moss-like flowering cushion plant in the family Caryophyllaceae, found on subantarctic islands in the southern Indian Ocean. The specific epithet refers to the type locality – the Kerguelen Islands.
Hakea leucoptera, commonly known as silver needlewood, needle hakea, pin bush or water tree and as booldoobah in the Koori language, is a shrub or small tree with rigid, cylindrical, sharply pointed leaves and white, cream-coloured or yellow flowers in late spring and early summer. It is widespread and common in central parts of the Australian mainland.
Tasmanian cushion plants are low growing, highly compact, woody, spreading mats that can grow up to 3 m in diameter, located mainly on the island of Tasmania. These mats are made up of tightly packed stems that grow at the same rate so that no apical rosettes protrude above the rest. The term cushion plant refers to a characteristic growth habit adopted by various species from a range of families to adapt to alpine and subalpine environments and areas of high latitude. They are adapted to grow in low nutrient areas and typically have deep taproots. Cushion plants are very slow growing and do not grow high above ground; mounds typically remain under 30 cm high. Underneath the living surface of the cushion, the plants either allow dead leaves to persist or produce non-photosynthetic material, resulting in an insulating effect.
The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line. These flora often occur in alpine fell-fields. The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
Eremophila foliosissima, commonly known as poverty bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a small, erect, densely foliaged shrub with long, narrow, hairy leaves and mauve to purple flowers. It is similar to Eremophila gilesii but is more dense and rounded, has more crowded leaves and has different hairs on the flowers.
Rubus tricolor is an evergreen prostrate shrub, native to southwestern China. Leaves are dark green above, pale green below, and stems have red bristles. It has white flowers in summer and edible red fruit. It grows approximately 0.3 m (0.98 ft) high and usually forming a vigorously spreading, dense mat. In cultivation, it is mainly used as groundcover. Common names include Chinese bramble, groundcover bramble, creeping bramble, Korean raspberry, Himalayan bramble, and groundcover raspberry. In Chinese, it is called 三色莓.
Oreobolus pectinatus is a species of flowering plant in the sedge family that is native to the subantarctic islands, and to the North and South Islands of New Zealand. The specific epithet derives from the Latin, pectin/pectinis,, and refers to the leaves.
Abrotanella forsteroides, commonly known as the Tasmanian cushion plant, is an endemic angiosperm of Tasmania, Australia. The plant is a dicot species of the daisy family Asteraceae and can be identified by its bright green and compact cushion like appearance.
Distichia muscoides is a species of plant in the rush family Juncaceae. It is native to the Andes of South America where it grows in upland wetland areas known as bofedales.
Dracophyllum muscoides, commonly known as cushion inaka, is a small cushion plant in the family Ericaceae. It is endemic to New Zealand and is found only in the South Island in sub-alpine regions.
Dudleya anomala is a rare species of succulent plant in the family Crassulaceae commonly known as the Todos Santos liveforever. With a dense, cushion-forming habit, this leaf succulent is characterized by elongated stems, slightly sticky leaves, and bell-shaped flowers with white, spreading petals. This species is native to Baja California, Mexico, and is found primarily on islands and one coastal locality.
Myosotis pulvinaris is a species of flowering plant in the family Boraginaceae, endemic to the South Island of New Zealand. Joseph Dalton Hooker described the species in 1867. Plants of this species of forget-me-not are perennial with a prostrate, compact, cushion habit, short bracteate inflorescences, and white corollas.
Myosotis uniflora is a species of flowering plant in the family Boraginaceae, endemic to the South Island of New Zealand. Joseph Dalton Hooker described the species in 1867. Plants of this species of forget-me-not are perennial with a prostrate, compact, cushion or mat habit, short bracteate inflorescences, and cream to yellow corollas.
Myosotis albosericea is a species of flowering plant in the family Boraginaceae, endemic to the South Island of New Zealand. Joseph Dalton Hooker described the species in 1867. Plants of this species of forget-me-not are perennial rosettes which form loose clumps, with ebracteate, erect inflorescences, and yellow corollas.
