Glehnia littoralis F. Schmidt ex Miq. | |
Glehnia is a genus of plants in the carrot family, Apiaceae. It is monotypic, being represented by the single species, Glehnia littoralis, [1] commonly known as beach silvertop and American silvertop. The genus was named after Russian botanist Peter von Glehn. [2]
It is a long-taprooted plant forming a basal patch of leaves, with each leaf made up of several rounded, lobular segments. It reaches a maximum height exceeding .5 metres (1+1⁄2 feet), with the North American subspecies only reported to reach 6.5 centimetres (2+1⁄2 inches). [3] The plant's erect stem is topped with an umbel of carrotlike white flowers.
The plant contains naphthisoxazole A. [4]
Two subspecies exist, one in Asia and one in North America; the latter is named leiocarpa. [3]
It is native to eastern Asia, particularly eastern China, Japan, and far-eastern Russia, and western North America from Alaska to northern California. It can be found on sandy beaches and dunes. [3]
The plant is perhaps best known as a Chinese herbal remedy for cough. [5]
Pears are fruits produced and consumed around the world, growing on a tree and harvested in late summer into mid-autumn. The pear tree and shrub are a species of genus Pyrus, in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees.
Sassafras is a genus of three extant and one extinct species of deciduous trees in the family Lauraceae, native to eastern North America and eastern Asia. The genus is distinguished by its aromatic properties, which have made the tree useful to humans.
Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly referred to as elder, elderflower or elderberry.
The horned lark or shore lark is a species of lark in the family Alaudidae found across the northern hemisphere. It is known as "horned lark" in North America and "shore lark" in Europe.
Cercis is a genus of about 10 species in the subfamily Cercidoideae of the pea family Fabaceae. It contains small deciduous trees or large shrubs commonly known as redbuds in the USA. They are characterised by simple, rounded to heart-shaped leaves and pinkish-red flowers borne in the early spring on bare leafless shoots, on both branches and trunk ("cauliflory"). The genus contains ten species, native to warm temperate regions of North America, southern Europe, western and central Asia, and China.
Alisma plantago-aquatica, also known as European water-plantain, common water-plantain or mad-dog weed, is a perennial flowering aquatic plant widespread across most of Europe and Asia, and apparently spread elsewhere in both the Old and New World.
Cornus canadensis is a species of flowering plant in the dogwood family Cornaceae, native to eastern Asia and North America. Common names include Canadian dwarf cornel, Canadian bunchberry, quatre-temps, crackerberry, and creeping dogwood. Unlike its relatives, which are for the most part substantial trees and shrubs, C. canadensis is a creeping, rhizomatous perennial growing to about 20 centimetres tall.
Maianthemum racemosum, the treacleberry, feathery false lily of the valley, false Solomon's seal, Solomon's plume or false spikenard, is a species of flowering plant native to North America. It is a common, widespread plant with numerous common names and synonyms, known from every US state except Hawaii, and from every Canadian province and territory, as well as from Mexico.
Mentha arvensis, the corn mint, field mint, or wild mint, is a species of flowering plant in the mint family Lamiaceae. It has a circumboreal distribution, being native to the temperate regions of Europe and western and central Asia, east to the Himalaya and eastern Siberia, and North America. Mentha canadensis, the related species, is also included in Mentha arvensis by some authors as two varieties, M. arvensis var. glabrata Fernald and M. arvensis var. piperascens Malinv. ex L. H. Bailey.
Lonicera caerulea, also known by its common names blue honeysuckle, sweetberry honeysuckle, fly honeysuckle, blue-berried honeysuckle, or the honeyberry, is a non-climbing honeysuckle native throughout the cool temperate Northern Hemisphere regions of North America, Europe, and Asia.
Banksia seminuda, commonly known as the river banksia, is a tree in the plant genus Banksia. It is found in south west Western Australia from Dwellingup (32°42′ S) to the Broke Inlet east of Denmark (34°57′ S). It is often mistaken for, and was originally considered a subspecies of, the Banksia littoralis. Stephen Hopper described the subspecies remanens as a short-leaved shrubby form found in the coastal sands below granite outcrops in the Walpole-Nornalup National Park, however George does not feel this form warrants taxonomic recognition as it lies within the normal variability of the species and there was no clear distinction between it and the other populations of B. seminuda.
Banksia blechnifolia is a species of flowering plant in the genus Banksia found in Western Australia. It was first described by Victorian state botanist Ferdinand von Mueller in 1864, and no subspecies are recognised. It gained its specific name as its leaves are reminiscent of a fern (Blechnum). B. blechnifolia is one of several closely related species that grow as prostrate shrubs, with horizontal stems and leathery, upright leaves. The red-brown flower spikes, known as inflorescences, are up to 20 centimetres (8 in) high and appear from September to November in the Australian spring. As the spikes age, each turns grey and develops as many as 25 woody seed pods, known as follicles.
Veratrum is a genus of flowering plants in the family Melanthiaceae. It occurs in damp habitats across much of temperate and subarctic Europe, Asia, and North America.
Commelina communis, commonly known as the Asiatic dayflower, is an herbaceous annual plant in the dayflower family. It gets its name because the blooms last for only one day. It is native throughout much of East Asia and northern parts of Southeast Asia. In China, the plant is known as yazhicao, roughly translating to "duckfoot herb", while in Japan it is known as tsuyukusa, meaning "dew herb". It has also been introduced to parts of central and southeastern Europe and much of eastern North America, where it has spread to become a noxious weed. It is common in disturbed sites and in moist soil. The flowers emerge from summer through fall and are distinctive with two relatively large blue petals and one very small white petal.
Mentha canadensis is a species of mint native to North America and the eastern part of Asia. In North America, it is commonly known as Canada mint, American wild mint, and in Asia as Chinese mint, Sakhalin mint, Japanese mint, and East Asian wild mint. The flowers are bluish or have a slight violet tint. The plant is upright, growing to about 4–18 in (10–46 cm) tall. Leaves grow opposite from each other, and flower bunches appear in the upper leaf axils. The mint grows in wet areas but not directly in water, so it will be found near sloughs, and lake and river edges. Plants bloom from July to August in their native habitats.
Anaphalis margaritacea, commonly known as the western pearly everlasting or pearly everlasting, is an Asian and North American species of flowering perennial plant in the family Asteraceae.
A pitaya or pitahaya is the fruit of several different cactus species indigenous to the region of southern Mexico and along the Pacific coasts of Guatemala, Costa Rica, and El Salvador. Pitaya is cultivated in East Asia, South Asia, Southeast Asia, the United States, the Caribbean, Australia, Brazil, and throughout tropical and subtropical regions of the world.
Malus baccata is an Asian species of apple known by the common names Siberian crab apple, Siberian crab, Manchurian crab apple and Chinese crab apple. It is native to many parts of Asia, but is also grown elsewhere as an ornamental tree and for rootstock. It is used for bonsai. It bears plentiful, fragrant, white flowers and edible red to yellow fruit of about 1 cm diameter.
Hymenocallis littoralis, commonly known as the beach spider lily, is a species of plant in the amaryllis family Amaryllidaceae. It is native to warmer coastal regions of Latin America and a widely cultivated and naturalized plant in many tropical countries.
Juncus balticus is a species of rush known by the common name Baltic rush. It is a perennial flowering plant in the family Juncaceae. It can reach a height of about 75 centimetres. It is native to north-western Europe from Spain to northern European Russia, most of North America except the south-eastern United States, parts of Mexico and Central America, and western and southern South America from Colombia to Argentina. It is available from specialist nurseries for landscaping and soil stabilization purposes.
