Dicentra
''Dicentra'' (Ancient Greek, Greek ''dís'' "twice", ''kéntron'' "spur"), known collectively as the bleeding-hearts, is a genus containing eight species of herbaceous plant, herbaceous Flowering plant, flowering perennial plants with unique, "heart"-shaped Flower, flowers and finely divided Leaf, foliage. The species are, primarily, native plant, native to North America, although several are found in temperate East Asia. Description and growth requirements Flowers have two tiny sepals and four petals. The flowers are bisymmetric: the two outer petals are spur (botany), spurred or pouched at the base and curved outwards or backwards at the tip, and the two inner ones with or without a crest at the tip. In ''Dicentra'', all leaves are in a basal rosette (botany), rosette, and flowers are on leafless pedicel (botany), stalks. In other genera with bisymmetric heart-shaped flowers (''Lamprocapnos'', ''Dactylicapnos'', ''Ichtyoselmis'', ''Ehrendorferia''), leaves grow on stems as well ...

Dicentra Cucullaria
''Dicentra cucullaria'', Dutchman's britches, or Dutchman's breeches, is a perennial herbaceous plant, native to rich woods of eastern North America, with a disjunct population in the Columbia Basin. The common name Dutchman's breeches derives from their white flowers that look like white breeches. Description The rootstock is a cluster of small pink to white teardrop-shaped bulblets (more precisely, miniature tubers). Leaves are long and broad, with a petiole (leaf stalk) long. They are trifoliate, with finely divided leaflets. The flowers are usually white, rarely suffused with pink, long. They are produced in early spring in racemes of 3 to 14 flowers on peduncles (flower stalks) long. Unlike the closely related '' Dicentra canadensis'' (squirrel corn), the flowers lack fragrance. The pistil of a pollinated flower develops into a slender pod long and , narrowed to a point on both ends. The capsule splits in half when the seeds are ripe. The seeds are kidney-s ...

Lamprocapnos
''Lamprocapnos spectabilis'', commonly known as bleeding heart or Asian bleeding heart, is a species of flowering plant belonging to the fumitory subfamily (Fumarioideae) of the Papaveraceae (poppy family). It is native to Northeast China and the Korean peninsula; however, it has been introduced by humans into a larger area of Northeast Asia, including parts of Siberia, Russia and Japan. It is the sole species in the monotypic genus ''Lamprocapnos'', but is still widely sold under the obsolete name ''Dicentra spectabilis'' (now listed as a synonym), not to be confused with the North American native bleeding heart plants of the genus Dicentra. It is valued in flower gardens for the heart-shaped pink and white flowers it produces in spring.Tebbit, Mark, Lidén, Magnus and Zetterlund, Henrik, ''Bleeding Hearts, Corydalis and their relatives'', pub.

Ichtyoselmis
''Ichtyoselmis macrantha'' (also spelled ''Ichthyoselmis''; formerly known as ''Dicentra macrantha''; large-flowered dicentra) is the only species in the genus ''Ichtyoselmis''. It is a perennial plant growing from a long rhizome, native to woodland and glades at elevations of in northern Burma and southern China. In Sichuan Province, China, it is known as goldfish plant, because of the shape and color of the flowers. Etymology ''Ichtyoselmis'' comes from Greek (', "fish") and ' ("fishing line"). Although the correct spelling of the Greek word uses ''th'' (theta), the scientific name uses ''t''. Description Leaves are divided in threes twice or three times and toothed. Flowers hang at the end of leafy stems up to tall in cymes of 3-14 flowers and have two long, thin sepals and four cream to pale yellow petal Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dactylicapnos
''Dactylicapnos'' (climbing dicentra; formerly included in ''Dicentra'') is a genus of frost-tender perennial or annual climbers native to the Himalayas, northern Burma, central southern China, and northern Vietnam. Description Leaves are compound, with leaflets arranged in threes (perennial species) or pinnately (mostly annuals). The leaflet at the end of each leaf is transformed into a branched tendril. Flowers are heart-shaped and have four pale yellow to orange petals. The outer petals are pouched at the base and bent slightly outwards at the tip. The fruit is a capsule with two valves, dehiscent Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part. Structures that op ... in most species, but indehiscent in ''D. scandens''.

Gynoecium
Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl (botany), whorl of a flower; it consists of (one or more) ''#Pistil, pistils'' and is typically surrounded by the pollen-producing plant reproductive morphology, reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, Marchantiophyta, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeast Asia
Northeast Asia or Northeastern Asia is a geographical Subregion#Asia, subregion of Asia. Its northeastern landmass and islands are bounded by the Pacific Ocean, North Pacific Ocean. The term Northeast Asia was popularized during the 1930s by American historian and political scientist Robert Kerner. Under Kerner's definition, "Northeast Asia" includes the Japanese archipelago, Japanese Archipelago, the Korea, Korean Peninsula, the Mongolian Plateau, the Northeast China Plain, and East Siberian Mountains, the mountainous regions of the Russian Far East, stretching from the Lena (river), Lena River in the west to the Pacific Ocean in the east. Definitions The definition of Northeast Asia is not static but often changes according to the context in which it is discussed. The subregion of Northeast Asia comprises China, Japan, and Korea, usually also including Mongolia and Siberia. Parts or the whole of Northern and southern China, northern China are also frequently included in source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. The stalk at the base of a leaf is called a petiole. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts.

Pacific Northwest
The Pacific Northwest (PNW; ) is a geographic region in Western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east. Though no official boundary exists, the most common conception includes the U.S. states of Oregon, Washington (state), Washington, Idaho, and the Canadian province of British Columbia. Some broader conceptions reach north into Alaska and Yukon, south into Northern California, and east into western Montana. Other conceptions may be limited to the coastal areas west of the Cascade Mountains, Cascade and Coast Mountains, Coast mountains. The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as "British Columbia Interior, the Interior" in British Columbia), is the inland region. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a Aerial stem modification, modified stem in which the internode (botany), internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of Gall, galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant family (taxonomy), families have varieties with rosette Morphology (biology), morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern ''Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
