Epilobium tetragonum | |
Epilobium tetragonum, commonly known as the square stalked willow herb, is a species of flowering plant in the willowherb family Onagraceae.
The erect perennial herb typically grows to a height of 0.1 to 1.3 metres (0.3 to 4.3 ft) and can have several stems. It blooms between January and November[ clarification needed ] and produces pink-purple flowers.
The species has become naturalised in the Perth and Peel regions of Western Australia. [1]
Epilobium tetragonum is characterized by its distinctive square-shaped stem, with leaves evenly spaced in a tetragonal arrangement around the stem, giving the plant a square-like appearance. The leaves are hairless and solid green and have a unique shimmer in direct sunlight. [2]
Chamaenerion angustifolium is a perennial herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb. In the United Kingdom it is also known as bombweed, as a result of its rapid appearance on city bomb sites during the Blitz of World War II; the plant is also traditionally known as Saint Anthony's laurel. It is also known by the synonyms Chamerion angustifolium and Epilobium angustifolium. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.
Epilobium is a genus of flowering plants in the family Onagraceae, containing about 197 species. The genus has a worldwide distribution. It is most prevalent in the subarctic, temperate and subantarctic regions, whereas in the subtropics and tropics Epilobium species are restricted to the cool montane biomes, such as the New Guinea Highlands.
Teucrium is a cosmopolitan genus of flowering plants in the family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.
Agonis flexuosa is a species of tree that grows in the south west of Western Australia. It is easily the most common of the Agonis species, and is one of the most recognisable trees of Western Australia, being commonly grown in parks and on road verges in Perth.
Scutellaria galericulata, the common skullcap, marsh skullcap or hooded skullcap, is a hardy perennial herb native to northern areas of the Northern Hemisphere, including Europe, Asia, and almost all of Canada. It is a member of the mint family. The form is upright and is usually 20-45 centimeters in height, sometimes reaching up to 80 cm. It is a wetland-loving species and grows along fens and shorelines. The blue flowers are 1 to 2 centimeters long. The flowers are in pairs and are all on the same side of the stem. The flowers do not appear at the top of the stem.
Prunella vulgaris, the common self-heal, heal-all, woundwort, heart-of-the-earth, carpenter's herb, brownwort or blue curls, is a herbaceous plant in the mint family Lamiaceae.
Chamaenerion is a genus of flowering plants in the family Onagraceae. It has sometimes been included in the genus Epilobium. Members of the genus may be called willowherbs, or fireweeds, based on a common name used for C. angustifolium. They are upright herbaceous perennials, growing from a woody base or from rhizomes, with racemes of usually purple to pink flowers. All species are found in the northern hemisphere. Most occur in moist habitats; C. angustifolium is the exception, favouring disturbed ground.
Epilobium hirsutum is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie.
Epilobium ciliatum, known by the common names fringed willowherb, American willowherb, slender willow herb, and northern willow herb is a species of flowering plant in the willowherb family Onagraceae. This species is native to much of North America, southern South America, and East Asia. It is an introduced species in much of Eurasia and Australia.
Epilobium minutum is a species of willowherb known by the common names little willowherb, chaparral willowherb and desert willowherb. It is also called "smallflower willowherb" in reference to its small size relatively. However that name, in particular the British English variant "small-flowered willowherb", typically refers to Epilobium parviflorum.
Epilobium foliosum is a species of flowering plant in the evening primrose family known by the common names leafy willowherb and California willowherb. It is native to parts of western North America from British Columbia through California to Arizona, where it grows in many types of habitat, including disturbed areas.
Epilobium howellii is an uncommon species of flowering plant in the evening primrose family known by the common names Yuba Pass willowherb and subalpine fireweed. It is endemic to the High Sierra Nevada of California, where it is known from only about 20 occurrences.
Epilobium oregonense is a species of flowering plant in the evening primrose family known by the common name Oregon willowherb. It is native to western North America from British Columbia to Arizona, where it generally grows in moist places in several types of habitat. It is a perennial herb growing spindly erect stems approaching 40 centimeters high or sometimes forming mats spreading via stolons. The small leaves are rounded near the base of the plant and linear in shape farther up the stem. The inflorescence bears flowers with four white to pink petals each a few millimeters long. The fruit is an elongated capsule up to 5 centimeters in length which is borne on a long pedicel which may be longer than the capsule itself.
Epilobium pallidum is a species of flowering plant in the evening primrose family known by the common name largeflower spike-primrose. It is native to western United States, where it grows in moist areas in northern California, Oregon, and Idaho. It is an annual herb producing a narrow, upright stem up to 60 centimeters long lined with narrow oval leaves each up to 5 centimeters in length. The inflorescence atop the stem bears several flowers and hairy, leaflike bracts. Each flower has four bilobed petals each up to about a centimeter long and bright pink in color. The fruit is a beaked capsule between 1 and 2 centimeters long containing a row of tiny seeds.
Dendrobium tetragonum, commonly known as the tree spider orchid, is a variable species of epiphytic or lithophytic orchid endemic to eastern Australia. Tree spider orchids are unusual in having pendulous pseudobulbs that are thin and wiry near the base then expand into a fleshy, four-sided upper section before tapering at the tip. There are only a few thin but leathery leaves at the end of the pseudobulbs and up to five flowers on relatively short flowering stems. To allow for the variations in the species there are five subspecies and a variety, some with a unique common name.
Epilobium parviflorum, commonly known as the hoary willowherb or smallflower hairy willowherb, is a herbaceous perennial plant of the family Onagraceae.
Epilobium brunnescens is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is a small, creeping, perennial plant with white or pale pink flowers. It is native to New Zealand and south-east Australia and has been introduced to Northern Europe. Its common names include New Zealand willowherb in Great Britain and Ireland, creeping willowherb in New Zealand and bog willowherb for the Australian subspecies.
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.
Epilobium billardierianum, commonly known as the glabrous willow herb or smooth willow herb, is a species in the family Onagraceae that is native to Australia and New Zealand.
Epilobium coloratum, known by the common names purpleleaf willowherb and cinnamon willow-herb, is a species of flowering plant in the genus Epilobium of the willowherb family Onagraceae. This species is native to the Midwest and Eastern United States, as well as the Canadian provinces of Ontario, Québec, New Brunswick, Nova Scotia, and Newfoundland. It is also native to the Dominican Republic and Haiti.
