Ericameria Martirensis
''Ericameria'' is a genus of North American shrubs in the family Asteraceae. ''Ericameria'' is known by the common names goldenbush, rabbitbrush, turpentine bush, and rabbitbush. Most are shrubs, but one species ''( E. parishii)'' can reach tree stature. They are distributed in western Canada (Saskatchewan, Alberta, British Columbia) western United States (from the western Great Plains to the Pacific) and northern Mexico. Bright yellow flower heads adorn the plants in late summer. All the species have disc florets, while some have ray florets but others do not. ''Ericameria nauseosa'', (synonym ''Chrysothamnus nauseosus''), is known for its production of latex. Etymology ''Ericameria'' is based on the genus name ''Erica'' and the Greek word ''meros'' ('part'), in reference to the similarity of the plant's leaves to those of ''Erica''. Uses This genus has a number of admirable landscape plants for heavily alkaline soils, but most species need extensive rejuvenation pruning e ...

Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus '' Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 millimetres long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up to tall. All are evergreen, with minute, needle-like leaves long. Flowers are sometimes axillary, and sometimes borne in terminal umbels or spikes, and are usually outward or downward facing. The seeds are very small, and in some species may survi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lepidoptera
Lepidoptera ( ) or lepidopterans is an order (biology), order of winged insects which includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 family (biology), families and 46 Taxonomic rank, superfamilies, and one of the most widespread and widely recognizable insect orders in the world. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, large triangular Insect wing, wings, and a proboscis for siphoning nectars. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs is normally performe ...

Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the lar ...

Pruning
Pruning is the selective removal of certain parts of a plant, such as branches, buds, or roots. It is practiced in horticulture (especially fruit tree pruning), arboriculture, and silviculture. The practice entails the targeted removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants. Woody plants may undergo a process referred to as ''self-pruning'', where they will drop twigs or branches which are no longer producing more energy than they require. It is theorized that this process can also occur in response to lack of water, in order to reduce the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkaline
In chemistry, an alkali (; from the Arabic word , ) is a basic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word ''alkali'' is derived from Arabic ''al qalīy'' (or ''alkali''), meaning (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lime''), a far more strongly basic substance known as ''caustic ...
