Hydrocharis Laevigata
''Hydrocharis laevigata'' is a floating aquatic plant, and is a member of the family Hydrocharitaceae. Common names include West Indian spongeplant, South American spongeplant and Amazon or smooth frogbit. This plant was introduced to North American waterways through use in aquariums and aquascapes. Plant origin and distribution Spongeplant originates from fresh water habitats of tropical and subtropical Mexico Central America, the Caribbean, and South America. It has been introduced to other parts of the world including California, France, Spain, Sweden, Poland, Japan, western and eastern Australia, Zambia, Zimbabwe, and Java. In California it has been introduced as an ornamental pond plant, and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento River delta and the San Joaquin River, and ponds and irrigation canals. It is an invasive species in Chile where it has been found from Elqui River in the north to Carlos Anwandter Natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elqui River
The Elqui River starts in the west Andes and flows into the Pacific Ocean near the Chilean city of La Serena. It flows through a wine and pisco producing area. Vicuña, the main town of the middle valley, was the home of Nobel Laureate poet Gabriela Mistral. The invasive plant species '' Limnobium laevigatum'' is present in the river which is its northernmost locale in Chile. Indigenous cultures of the Elqui Valley About a quarter of the toponymy in Elqui Valley is of indigenous origin, overwhelmingly Quechua and Mapuche. There is scant Diaguita (Kakan) toponyy known in the area despite it being considered a homeland of that people by various authors. Quechua toponymy is related to valleys incorporation to the Inca Empire in the late 15th and early 16th-century. Some Mapuche toponymy posdates Inca rule, but other may be coeval or even precede it. Toponyms recognised as Nahua, Kunza, Diaguita, Aymara and Taino make together up less than 10% of the all placenames in Elqui V ...

Aquatic Plants
Aquatic plants, also referred to as hydrophytes, are vascular plants and non-vascular plants that have adapted to live in aquatic environments ( saltwater or freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.Sculthorpe, C. D. 1967.

Hydrilla Verticillata
''Hydrilla'' (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, ''Hydrilla verticillata'', though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.Flora Europaea''Hydrilla''/ref>Flora of Taiwan''Hydrilla'' The stems grow up to 1–2 m long. The leaves are arranged in whorls of two to eight around the stem, each leaf 5–20 mm long and 0.7–2 mm broad, with serrations or small spines along the leaf margins; the leaf midrib is often reddish when fresh. It is monoecious (sometimes dioecious), with male and female flowers produced separately on a single plant; the flowers are small, with three sepals and three petals, the petals 3–5 mm long, transparent with red streaks. It reproduces primarily vegetatively by fragmentation and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Plant propagation Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. W ...

Spatulate
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocharis Spongia
''Hydrocharis spongia'', commonly known as American frogbit, is a species of flowering plant in the family Hydrocharitaceae. It is native to the central and southeastern United States, where it grows in the Lower Mississippi Valley as far north as Illinois, and on the Southern Coastal Plain from Texas to Delaware. It is occasionally found elsewhere as a waif. Image It grows in the slow-moving water of streams, bayous, and lakes from sea level up to 100 meters elevation. The plants are herbaceous, growing up to 50 cm long. Heart-shaped or nearly rounded leaves are floating or emersed, 1–3 in (2–7 cm) in diameter. The leaves have two forms, often on the same plant. Floating leaves have a thick layer of spongy [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
