West Palm Valley, Nihoa, Northwestern Hawaiian Islands, USA-2012
West or Occident is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth. Etymology The word "west" is a Germanic word passed into some Romance languages (''ouest'' in French, ''oest'' in Catalan, ''ovest'' in Italian, ''oeste'' in Spanish and Portuguese). As in other languages, the word formation stems from the fact that west is the direction of the setting sun in the evening: 'west' derives from the Indo-European root ''*wes'' reduced from ''*wes-pero'' 'evening, night', cognate with Ancient Greek ἕσπερος hesperos 'evening; evening star; western' and Latin vesper 'evening; west'. Examples of the same formation in other languages include Latin occidens 'west' from occidō 'to go down, to set' and Hebrew מַעֲרָב maarav 'west' from עֶרֶב erev 'evening'. Navigation To go west using a compass for navigation (in a place where magnetic north is the same dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schiedea Verticillata
''Schiedea verticillata'', known as the Devils Slide schiedea or Nihoa carnation, is an endangered species of plant in the family Caryophyllaceae, endemic to the island of Nihoa in the Northwestern Hawaiian Islands, where it was discovered in 1923 by the ''Tanager'' Expedition. It has been listed as endangered since 1996. It has stems long, erect or sometimes trailing, and fleshy mint-colored leaves as long as 15 cm. The flowers are petal-less, have ten stamens and 4-5 styles. The plant estivates, dying back to the fleshy perennial roots during the dry season. Less than 400 individual plants survive in two of Nihoa's rocky valleys, but the population has remained stable. How this plant is pollinated is not known. Even though there are very few individuals surviving, the carnation can avoid inbreeding, a problem that threatens fellow Nihoan plant ''Amaranthus brownii'', because this carnation has the highest genetic diversity of its genus.

Solanum Americanum
''Solanum americanum'', commonly known as American black nightshade, small-flowered nightshade or glossy nightshade, is a herbaceous flowering plant of wide though uncertain native range. The certain native range encompasses the tropics and subtropics of the Americas, Melanesia, New Guinea, and Australia. The plant is widely naturalised around the tropical Pacific and Indian Oceans, including Hawaii, Indochina, Madagascar and Africa, possibly via anthropogenic introduction in these locales. ''Solanum americanum'' is one of the most widespread and morphologically variable species belonging to the section ''Solanum''. It can be confused with other black nightshade species in the ''Solanum nigrum'' complex. Description ''Solanum americanum'' grows up to tall and is an annual or short-lived perennial. The leaves are alternate on the branch, and vary greatly in size, up to long and broad, with a petiole and a coarsely wavy or toothed margin. The flowers are about 1 cm diam ...

Portulaca
''Portulaca'' (, is the type genus of the flowering plant family Portulacaceae, with over 100 species, found in the tropics and warm temperate regions. They are known as the purslanes. Common purslane (''Portulaca oleracea'') is widely consumed as an edible plant, and in some areas it is invasive. ''Portulaca grandiflora'' is a well-known ornamental garden plant. Purslanes are relished by chickens. Some ''Portulaca'' species are used as food plants by the larvae of some Lepidoptera species including the nutmeg moth (''Hadula trifolii''). Species The following species are accepted: *''Portulaca africana'' (Danin & H.G.Baker) Danin – Western Africa to south China *''Portulaca almeviae'' Ocampo – Mexico *''Portulaca amilis'' Speg. – Paraguayan purslane – Peru to Brazil and N.

Portulaca Oleracea
''Portulaca oleracea'' (common purslane, also known as little hogweed, or pursley) is an annual (actually tropical perennial in USDA growing zones 10–11) succulent in the family Portulacaceae. Description The plant may reach in height. It has smooth, reddish, mostly prostrate stems and the leaves, which may be alternate or opposite, are clustered at stem joints and ends. The yellow flowers have five regular parts and are up to wide. Depending upon rainfall, the flowers appear at any time during the year. The flowers open singly at the center of the leaf cluster for only a few hours on sunny mornings. The tiny seeds are formed in a pod, which opens when the seeds are mature. Purslane has a taproot with fibrous secondary roots and is able to tolerate poor soil and drought. The fruits are many-seeded capsules. Seed set is considerable; one plant can develop up to 193,000 seeds. The seeds germinate optimally at a temperature above 25 °C; they are light germinators, with ...

Portulaca Lutea
''Portulaca lutea'', the native yellow purslane, is a species of ''Portulaca'' that is indigenous to all of the main islands of Hawaii except for Kaua'i and is widespread throughout the Pacific Islands. Ecology ''Portulaca lutea'' is very much like ''Sesuvium portulacastrum'' , it is a pan tropical, sea-dispersed beach succulent that can spread and even travel as vegetative fragments which are tolerant of salt water and root easily on landing. It grows on a variety of soils, including lava, coral and sand dunes, in coastal areas from sea level to 390 metres above sea level. Appearance The leaves are oval to round and range in size to 24 mm long. One to three yellow flowers are borne at the ends of the stems.

Rumex
The docks and sorrels, genus ''Rumex'', are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family, Polygonaceae. Members of this genus are very common perennial herbs with a native almost worldwide distribution, and introduced species growing in the few places where the genus is not native. Some are nuisance weeds (and are sometimes called dockweed or dock weed), but some are grown for their edible leaves. ''Rumex'' species are used as food plants by the larvae of a number of Lepidoptera species, and are the only host plants of ''Lycaena rubidus.'' Description They are erect plants, usually with long taproots. The fleshy to leathery leaves form a basal rosette at the root. The basal leaves may be different from those near the inflorescence. They may or may not have stipules. Minor leaf veins occur. The leaf blade margins are entire or crenate. The usually inconspicuous flowers are carried above the leaves in clusters. The fertile flowers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boerhavia
''Boerhavia'' is a genus of over 100 species in the Nyctaginaceae family. The genus was named for Herman Boerhaave, a Dutch botanist, and the genus name is frequently misspelled "''Boerhaavia''". Common names include spiderlings and hogweeds. Taxonomy There are over 100 species in the genus ''Boerhavia'', which is in the family Nyctaginaceae, which includes the four o'clock flower. The genus was named for the Dutch botanist Herman Boerhaave, and often misspelt as "Boerhaavia". Common names include spiderlings and hogweeds. Description Some species are annuals and others perennials. In habit they generally are herbaceous. "Spiderling" refers to the appearance of those species that bear inflorescences on numerous long, slender stems, interlocking in a manner suggestive of a spider or spider's web. ''Boerhavia'' species generally are native to warm tropical regions. Significance Several species of ''Boerhavia'' are of importance as agricultural and horticultural weeds. Some are ...

Sida Fallax
''Sida fallax'', known as yellow ilima or golden mallow, is a species of herbaceous flowering plant in the ''Hibiscus'' family, Malvaceae, indigenous to the Hawaiian Archipelago and other Pacific Islands. Plants may be erect or prostrate and are found in drier areas in sandy soils, often near the ocean. Ilima is the symbol of Laloimehani and is the flower for the islands of Oahu, Hawaii, and Abemama, Kiribati. It is known as ''ilima'' or ''āpiki'' in Hawaiian and as ''kio'' in Marshallese, ''te kaura'' in Kiribati, ''idibin ekaura'' in Nauruan, and ''akatā'' in Tuvalu. In Hawaiian religion, the ilima flowers are associated with Laka, the goddess of the hula, and the plant's prosrate form with Pele's brother, Kane-apua, the god of taro planters. Lei made from ilima were believed to attract mischievous spirits (thus its alternative name, ''āpiki''), although some considered them to be lucky.

Sesbania Tomentosa
''Sesbania tomentosa'', commonly known as Oahu riverhemp and ''ōhai'', is an endangered species of plant in the pea family, Fabaceae, that is endemic to the main Hawaiian Islands as well as Nihoa and Necker Island. It inhabits low shrublands and, rarely, dry forests, at elevations from sea level to . Associated native plant species include akiaki (''Sporobolus virginicus''), ilima (''Sida fallax''), naupaka kahakai (''Scaevola taccada''), and pili (''Heteropogon contortus''). Off-road vehicles, wildfires, grazing, and alien species competition have destroyed their habitat on the main islands, but they are still quite common on Nihoa and Necker. At least 2000 specimens grow on Nihoa, while there are far less on Necker. ''Ōhai'' is highly polymorphic, exhibiting broad variations in color and shape. Plants that grow on Nihoa have reddish-orange flowers and young leaflets that are relatively hairless. Necker plants have salmon to orange colored-flowers, and leaflets that are ve ...
