Many species appear totally dissimilar f ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobelia Erinus
''Lobelia erinus'' (edging lobelia, garden lobelia or trailing lobelia) is a species of flowering plant in the bellflower family Campanulaceae, native to southern Africa. Description It is a low growing, prostrate or scrambling herbaceous perennial plant growing to 8–15 cm tall. The basal leaves are oval, 10 mm long and 4–8 mm broad, with a toothed margin; leaves higher on the stems are slender and sometimes untoothed. The flowers are blue to violet in wild plants, with a five-lobed corolla 8–20 mm across; they are produced in loose panicles. About 0.5 to 4.5 inches long inflorescence stems are about 5 inches long, loose racemose inflorescences with many flowers. The hermaphrodite flower is zygomorphic with a length of up to 1 centimeter and quinate with double perianth. The five sepals are fused. The fan-shaped lower lip is trilobed. The color of the crown varies depending on the variety between white, blue, purple, pink or red and the center is yellow or white. The fiv ...

Hawaiian Lobelioids
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: ''Clermontia'' are typically branched shrubs or small trees, up to tall, with fleshy fruits; ''Cyanea'' and ''Delissea'' are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; ''Lobelia'' and ''Trematolobelia'' have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar ''Brighamia'' have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled . Many species have beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedding (horticulture)
In horticulture, bedding is temporary planting of fast-growing plants into flower beds to create colourful displays, during spring, summer or winter. Plants used for bedding are generally annuals, biennials or tender perennials; succulents are gaining in popularity. Some bedding plants are also referred to as "patio plants" because they are widely used in pots and other containers positioned on patios, terraces, decking and other areas around houses. Larger tender "conservatory plants" may also be moved out from greenhouses or conservatories and planted out in borders (or stood in their pots in sheltered positions) for the warmer months, then returned to shelter for the winter. The modern bedding plant industry breeds and produces plants with a neat, dwarf habit, which flower uniformly and reliably. They are bred primarily for use in large-scale bedding schemes where uniformity and predictability is of paramount importance, but this is often achieved by losing the plants' indivi ...

Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant is usually divided into two categories: tender, and hardy. (Some sources also use the erroneous terms "Half-hardy" or "Fully hardy".) Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobelia Siphilitica
''Lobelia siphilitica'', the great blue lobelia, great lobelia, or blue cardinal flower, is a plant species within the family Campanulaceae. It is an herbaceous perennial dicot native to eastern and central Canada and United States. There are two recognized varieties of Lobelia siphilitica, Var. ''siphilitica and Var. ludoviciana.'' Blooming from August to October, it is short-lived, lasting only for a few years. Although self-compatible, a flower is unable to offer pollen to itself and it must be pollinated by insects, primarily bumblebees. Bees use the lower three fused petals as a landing pad. A bee of correct weight will depress these petals on its way to the flower's nectar, this lowers the stigma wiping it against the bee's back. Description Morphology Growing up to four feet tall, Great lobelia has a single ridged, unbranched stem, which is smooth or sparsely hairy. Leaves are hairless or scarcely hairy, that vary in shape from elliptical to lance-like, slightly n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setaceous Hebrew Character
The setaceous Hebrew character (''Xestia c-nigrum'') is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. It is found in the Palearctic realm. It is a common species throughout Europe and North Asia and Central Asia, South Asia, China, Japan and Korea. It is also found in North America, from coast to coast across Canada and the northern United States to western Alaska. It occurs in the Rocky Mountains from Montana to southern Arizona and New Mexico. In the east, it ranges from Maine to North Carolina. It has recently been recorded in Tennessee. The forewings of this species are reddish brown with distinctive patterning towards the base; a black mark resembling the Hebrew letter ''nun'' () with a pale cream-coloured area adjacent to this mark. The hindwings are cream coloured. Description The wingspan is 35–45 mm. Forewing purplish grey or purplish fuscous with a leaden gloss; costal area at ...

Lepidoptera
Lepidoptera ( ) is an order of insects that includes butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scales that cover the bodies, wings, and a proboscis. 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 mem ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The 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. 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 larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are ...
