Japanese Knotweed
''Reynoutria japonica'', synonyms ''Fallopia japonica'' and ''Polygonum cuspidatum'', is a species of herbaceous perennial plant in the knotweed and buckwheat family Polygonaceae. Common names include Japanese knotweed and Asian knotweed. It is native to East Asia in Japan, China and Korea. In North America and Europe, the species has successfully established itself in numerous habitats, and is classified as a pest and invasive species in several countries. Japanese knotweed has hollow stems with distinct raised nodes that give it the appearance of bamboo, though it is not related. While stems may reach a maximum height of each growing season, it is typical to see much smaller plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves are broad oval with a truncated base, long and broad, with an entire margin. The flowers are small, cream or white, produced in erect racemes long in late summer and early autumn.

Martinus Houttuyn
Maarten Houttuyn or Houttuijn (1720 – 2 May 1798) Latinised as Martinus Houttuyn, was a Dutch naturalist. Houttuyn was born in Hoorn, studied medicine in Leiden and moved to Amsterdam in 1753. He published many books on natural history, e.g. ''Natuurlyke Historie of uitvoerige Beschryving der Dieren, Planten en Mineraalen, volgens het Samenstel van den Heer Linnaeus'', in 37 volumes (1761-1773), following Carl Linnaeus' division into the animal kingdom, the plant kingdom, and the mineral kingdom. His areas of interest encompassed Pteridophytes, Bryophytes and Spermatophytes. He died in Amsterdam. In botanical nomenclature, the standard author abbreviation ''Houtt.'' is applied to plants described by him. He is commemorated by the genus ''Houttuynia'', a member of the Saururaceae from China and Japan. Martinus Houttuyn was the co-writer of the volumes 2, 3, 4 and 5 of '' Nederlandsche Vogelen''.His name appears on the title pages ovol 2 an of ''Nederlandsche Vogelen''. ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ...

Houttuynia
''Houttuynia'' is a genus of two species in the Saururaceae native to Southeast Asia. One species, '' H. cordata'', is widely cultivated as a culinary herb. The genus was originally described in 1783 by Carl Peter Thunberg when he formally described ''H. cordata'' as the only species. It remained a monotypic genus until 2001 when Zheng Yin Zhu and Shi Liang Zhang discovered and described a second species native to China, '' H. emeiensis'' but the validity still unestablished.Wu Wei, Zheng Youliang, Chen Li, Wei Yuming, Yan Zehong, and Yang Ruiwu. 2005PCR-RFLP analysis of cpDNA and mtDNA in the genus ''Houttuynia'' in some areas of China.''Hereditas'' 142: 24-32.

Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...

Caersws Headg Row1
Caersws ( cy, Caersŵs; ) is a village and community on the River Severn, in the Welsh county of Powys (Montgomeryshire) west of Newtown, and halfway between Aberystwyth and Shrewsbury. It has a station on the Cambrian Line from Aberystwyth to Shrewsbury. At the 2011 Census, the community had a population of 1,586 – a figure which includes the settlements of Clatter, Llanwnnog and Pontdolgoch. The village itself had a population of slightly over 800. Etymology The name is derived from the Welsh placename elements "Caer-" and "Sŵs". "Caer" translates as "fort" and likely refers to the Roman settlement. The derivation of the second element is less certain. Thomas Pennant and later writers note that the fort was the termination of the Roman Road from Chester (via Meifod), the name of the road was ''Sarn Swsan'' or ''Sarn Swsog'' and it is thought that the town and the road share their etymology. The meaning of Swsan/Swsog is again, uncertain, but two local traditi ...
