Limnobium Laevigatum
''Limnobium laevigatum'' 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 Central and South America. 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. Description ''Limnobium laevigatum'' is a floating aquatic plant, which can be mistaken for water hyacinth ('' Eichornia crassipes'') due to their superficial similarity. Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface, a distinguishing character of the juvenile plant ...

Cordate (leaf Shape)
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing 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 "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Plants
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecologi ...

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''Australian Plant Name Index''Hydrilla''/ref> The stems grow up to 1–2m 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 prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Department Of Food And Agriculture
The California Department of Food and Agriculture (CDFA) is a cabinet-level agency in the government of California. Established in 1919 by the California State Legislature and signed into law by Governor William Stephens, the Department of Food and Agriculture is responsible for ensuring the state's food safety, the protection of the state's agriculture from invasive species, and promoting the California agricultural industry. The Department of Food and Agriculture maintains district and field offices in 32 counties across the state, and two extraterritorial offices in Hawaii and Arizona. This includes agricultural inspection stations at the state's borders. The California State Board of Food and Agriculture is an advisory board to the governor and secretary. , the Secretary of Agriculture was Karen Ross, who is a member of Governor Gavin Newsom's cabinet, having originally been appointed to that post by Governor Jerry Brown in January, 2011.

Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any 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. Background 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. While m ...

Hydrocharitaceae
Hydrocharitaceae is a flowering plant family including 16 known genera with a total of ca 135 known species (Christenhusz & Byng 2016), that including a number of species of aquatic plant, for instance the tape-grasses, the well known Canadian waterweed, and frogbit. The family includes both freshwater and marine aquatics. They are found throughout the world in a wide variety of habitats, but are primarily tropical. Description The species are annual or perennial, with a creeping monopodial rhizome with the leaves arranged in two vertical rows, or an erect main shoot with roots at the base and spirally arranged or whorled leaves. The leaves are simple and usually found submerged, though they may be found floating or partially emerse. As with many aquatics they can be very variable in shape – from linear to orbicular, with or without a petiole, and with or without a sheathing base. The flowers are arranged in a forked, spathe-like bract or between two opposite bracts. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
