Acorus Gramineus
''Acorus gramineus'', commonly known as Japanese sweet flag, Japanese rush, grassy-leaved sweet flag, and grass-leaf sweet flag, is a botanical species belonging to the genus ''Acorus'', native to Japan, Korea, and eastern Asia. The plant usually grows in wetlands and shallow water. Description This shrubby plant's long, narrow, slightly curved leaves may grow to 30 cm (12 inches) in height. It can grow fully or partially submerged, or in very moist soil, but it will usually only flower when at least partially submerged. Var. ''pusillus'' has slightly shorter, more rigid glossy green leaves, while var. ''variegatus'' has longer leaves streaked with yellow. Cultivation and uses ''Acorus gramineus'' spreads aggressively by rhizome, creating a nearly-seamless groundcover where conditions are favorable, and it is frequently used around the edges of ponds and water gardens, as well as submerged in freshwater aquaria. It can be propagated by dividing the fleshy underwater rh ...

Daniel Solander
Daniel Carlsson Solander or Daniel Charles Solander (19 February 1733 – 13 May 1782) was a Swedish naturalist and an apostle of Carl Linnaeus. Solander was the first university-educated scientist to set foot on Australian soil. Biography Solander was born in Piteå, Norrbotten, Sweden, to Rev. Carl Solander a Lutheran principal, and Magdalena (née Bostadia). Solander enrolled at Uppsala University in July 1750 and initially studied languages, the humanities and law. The professor of botany was the celebrated Carl Linnaeus, who was soon impressed by young Solander's ability and accordingly persuaded his father to let him study natural history. Solander travelled to England in June 1760 to promote the new Linnean system of classification. In February 1763, he began cataloguing the natural history collections of the British Museum, and was elected a Fellow of the Royal Society in June the following year. In 1768, Solander gained leave of absence from the British Museum and ...

Korea National Arboretum
Korea National Arboretum () is an over-500-year-old arboretum located in Pocheon city of Gyeonggi Province of South Korea. It is widely known as "Gwangneung Forest ()" by the public. It is designated as UNESCO World Network of Biosphere Reserves, World Network of Biosphere Reserve and the country's 11th Natural monuments of South Korea, natural monument. Its history can be traced back to Joseon Dynasty. The planting of large forests started during the reign of Sejo of Joseon. He and Queen Jeonghui designated the area for a tomb which later named ''Gwangneung.'' Their tomb is one of Royal Tombs of the Joseon Dynasty, a UNESCO World Heritage Site. Following the construction of the tomb, it and its surrounding areas were designated as royal forest and kept under strict protection which lasted throughout post-Joseon history. The area was devastated during the Korean war. From 1983 to 1987, the central government went under project to develop the area as an arboretum with a forest museum ...

Acorus
''Acorus'' is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage (the order Alismatales), that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots (e.g., Alismataceae, Posidoniaceae). However, modern phylogenetic studies demonstrate that ''Acorus'' is sister to all other monocots. Common names include calamus and sweet flag. The genus is native to North America and northern and eastern Asia, and naturalised in southern Asia and Europe from ancient cultivation. The known wild populations are diploid except for some tetraploids in eastern Asia, while the cultivated plants are sterile triploids, probably of hybrid origin between the diploid and tetraploid forms. Characteristics ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ...

Heian Period
The is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kanmu, moved the capital of Japan to Heian-kyō (modern Kyoto). means "peace" in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Two types of Japanese script emerged, including katakana, a phonetic script which was abbreviated into hiragana, a cursive alphabet with a unique writing method distinctive to Japan. This gave rise to Japan's famous vernacular literature, with many of its texts written by court women who were not as educated in Chinese compared to their male counterparts. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic f ...

The Pillow Book
is a book of observations and musings recorded by Sei Shōnagon during her time as court lady to Empress Consort Teishi during the 990s and early 1000s in Heian-period Japan. The book was completed in the year 1002. The work is a collection of essays, anecdotes, poems, and descriptive passages that have little connection to one another except for the fact that they are ideas and whims of Shōnagon's spurred by moments in her daily life. In it she included lists of all kinds, personal thoughts, interesting events in court, poetry, and some opinions on her contemporaries. While it is mostly a personal work, Shōnagon's writing and poetic skill makes it interesting as a work of literature, and it is valuable as a historical document. Shōnagon meant her writing in ''The Pillow Book'' for her eyes only, but part of it was accidentally revealed to the Court during her life: "she inadvertently left it er writingon a cushion she put out for a visiting guest, who eagerly carried it off ...

Freshwater Plants
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...
