Cinquefoil
''Potentilla'' is a genus containing over 300Guillén, A., et al. (2005)Reproductive biology of the Iberian species of ''Potentilla'' L. (Rosaceae).''Anales del Jardín Botánico de Madrid'' 1(62) 9–21. species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae. Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds. Some species are called tormentils, though this is often used specifically for common tormentil (''P. erecta''). Others are referred to as barren strawberries, which may also refer to '' P. sterilis'' in particular, or to the closely related ''Waldsteinia fragarioides''. Several other cinquefoils formerly included here are now separated in distinct genera - notably the popular garden shrub ''P. fruticosa'', now ''Dasiphora fruticosa''. Potentillas are generally found throughout the northern continents of the world (holarctic), though some occur in montane biomes ...

Potentilla Reptans
''Potentilla reptans'', known as the creeping cinquefoil, European cinquefoil or creeping tormentil, is a flowering plant in the family Rosaceae. A creeping perennial plant native to Eurasia and Northern Africa, ''Potentilla reptans'' has been naturalized elsewhere. Its trailing stems root at the nodes, and leaves are on long stalks. The plant blooms between June and August with yellow flowers that are about 2 cm in diameter and have five heart-shaped petals. ''P. reptans'', which can be easily confused with silverweed, often grows in crushed masonry in the South of England. The grizzled skipper ''Pyrgus'' is a genus in the skippers butterfly family, Hesperiidae, known as the grizzled skippers. The name "checkered" or "chequered skipper" may also be applied to some species, but also refers to species in the genera '' Burnsius'' and '' ... butterfly favors the plant.

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fragaria
''Fragaria'' () is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as ''Fragaria'' × ''ananassa''. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Description Strawberries are not berries in the botanical sense.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits. Etymology The genus name derives from ("strawberry") and , a suffix used to create feminine nouns and plant names. The Latin name is tho ...

Alchemilla
''Alchemilla'' is a genus of herbaceous perennial plants in the family Rosaceae, with the common name lady's mantle applied generically as well as specifically to ''Alchemilla mollis'' when referred to as a garden plant. The plant used as a herbal tea or for medicinal usage such as gynaecological disorders is '' Alchemilla xanthochlora'' or in Middle Europe the so-called common lady's mantle ''Alchemilla vulgaris''. There are about 700 species, the majority native to cool temperate and subarctic regions of Europe and Asia, with a few species native to the mountains of Africa and the Americas. Most species of ''Alchemilla'' are clump-forming or mounded perennials with basal leaves arising from woody rhizomes. Some species have leaves with lobes that radiate from a common point and others have divided leaves—both are typically fan-shaped with small teeth at the tips. The long-stalked, gray-green to green leaves are often covered with soft hairs, and show a high degree of water-re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agrimonia
''Agrimonia'' (from the Greek ), commonly known as agrimony, is a genus of 12–15 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere, with one species also in Africa. The species grow to between tall, with interrupted pinnate leaves, and tiny yellow flowers borne on a single (usually unbranched) spike. ''Agrimonia'' species are used as food plants by the larvae of some Lepidoptera species including grizzled skipper (recorded on ''A. eupatoria'') and large grizzled skipper. Species *''Agrimonia eupatoria'' – Common agrimony (Europe, Asia, Africa) *''Agrimonia gryposepala'' – Common agrimony, tall hairy agrimony (North America) *''Agrimonia incisa'' – Incised agrimony (North America) *''Agrimonia coreana'' – Korean agrimony (eastern Asia) *''Agrimonia microcarpa'' – Smallfruit agrimony (North America) *''Agrimonia nipponica'' – Japanese agrimony (eastern Asia) *''Agrimonia parviflora'' ...

Rose
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from L ...

Geum
''Geum'' , (Latinized Greek for "taste" referencing the roots of the plant) commonly called avens, is a genus of about 50 species of rhizomatous perennial plant, perennial herbaceous plants in the Rosaceae, rose family and its subfamily Rosoideae, widespread across Europe, Asia, North and South America, Africa, and New Zealand. They are closely related to ''Potentilla'' and ''Fragaria''. From a basal Rosette (botany), rosette of leaves, they produce flowers on wiry stalks, in shades of white, red, yellow, and orange, in midsummer. ''Geum'' species are evergreen except where winter temperatures drop below . The cultivars 'Lady Stratheden' (with yellow flowers), and 'Mrs J. Bradshaw' (with orange flowers) have gained the Royal Horticultural Society's Award of Garden Merit. ''Geum'' species are used as food by the larvae of some Lepidoptera species including the grizzled skipper.

Nut (fruit)
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an energy-dense and nutrient-rich food source. Botanical definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into a ne ...

Accessory Fruit
An accessory fruit is a fruit in which some of the flesh is derived not from the floral ovary but from some adjacent tissue exterior to the carpel.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. Accessory fruits are usually indehiscent. Terminology Alternative terms for accessory fruit are false fruit, spurious fruit, pseudofruit, or pseudocarp. These are older terms for accessory fruit that have been criticized as "inapt", and are not used by some botanists today. Examples The following are examples of accessory fruits listed by the plant organ from which the accessory tissue is derived: * Hypanthium-derived: pomes (e.g. apple and pear) * Perianth-derived: ''anthocarps'' of the Nyctaginaceae * Receptacle-derived: fig, mulberry, pineapple, and strawberry * Calyx-derived: ''Gaultheria procumbens'' and '' Syzygium jambos'' Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruits.

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] |
