Dicentra Canadensis, By Mary Vaux Walcott
''Dicentra'' (Greek ''dís'' "twice", ''kéntron'' "spur"), known as bleeding-hearts, is a genus of eight species of herbaceous plants with oddly shaped flowers and finely divided leaves, native to eastern Asia and North America. Description Flowers have two tiny sepals and four petals. The flowers are bisymmetric: the two outer petals are 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, and flowers are on leafless stalks. In other genera with bisymmetric heart-shaped flowers (''Lamprocapnos'', ''Dactylicapnos'', ''Ichtyoselmis'', ''Ehrendorferia''), leaves grow on stems as well as from the root. Each of the two compound stamens is composed of one median and two lateral half stamens fused together. The stamens and pistil are held between the inner petals. Seeds with elaiosomes are borne in long capsules. All parts are poisonous if ingested ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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-shaped ...

Spur (botany)
The botanical term “spur” is given to outgrowths of tissue on different plant organs. The most common usage of the term in botany refers to nectar spurs in flowers. * nectar spur * spur (stem) * spur (leaf) See also *Fascicle *Sepal *Petal *Tepal A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very ... * Calyx * Corolla Plant anatomy Plant morphology {{SIA ...

Dicentra Eximia
''Dicentra eximia'' (wild or fringed bleeding-heart, turkey-corn) is a flowering plant with fernlike leaves and oddly shaped flowers native to the Appalachian Mountains. It is similar to the Pacific bleeding-heart (''Dicentra formosa''), which grows on the Pacific Coast. ''Dicentra eximia'' is a perennial herb in the Papaveraceae family. Description Leaves are finely divided and gray-green, growing from the base of the plant. Flowers are pink and bloom in tight clusters at the top of leafless, fleshy stems above the leaves from mid-spring to autumn. The four petals are connected at the base. The two outer petals are pouched at the base and bent back at the tips. The inner petals are perpendicular to the outer petals and connected at the tip. The pistil is enclosed within the inner petals, and the two stamens are on either side. There are two tiny, triangular, pink sepals above the petals. Seeds are borne in a plump, pointed pod. They ripen to black while the pod is still green. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicentra Canadensis
''Dicentra canadensis'', the squirrel corn, is a flowering plant from eastern North America with oddly shaped white flowers and finely divided leaves. Description Squirrel corn has small yellow clustered bulblets (looking roughly like kernels of maize, corn), finely dissected leaf, leaves, and white heart-shaped flowers. The flowers are fragrant. It is a ephemeral plant, spring ephemeral, leafing out and flowering in spring and going dormancy, dormant in summer. Distribution and habitat It is native to temperate deciduous forest, deciduous woodland in eastern North America. It is also found among rock outcrops near mountains.

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Elaiosome
Elaiosomes ( grc, ἔλαιον ''élaion'' "oil" + ''sóma'' "body") are fleshy structures that are attached to the seeds of many plant species. The elaiosome is rich in lipids and proteins, and may be variously shaped. Many plants have elaiosomes that attract ants, which take the seed to their nest and feed the elaiosome to their larvae. After the larvae have consumed the elaiosome, the ants take the seed to their waste disposal area, which is rich in nutrients from the ant frass and dead bodies, where the seeds germinate. This type of seed dispersal is termed myrmecochory from the Greek "ant" (myrmex) and "circular dance" (khoreíā). This type of symbiotic relationship appears to be mutualistic, more specifically dispersive mutualism according to Ricklefs, R.E. (2001), as the plant benefits because its seeds are dispersed to favorable germination sites, and also because it is planted (carried underground) by the ants. Elaiosomes develop in various ways either from seed ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Gynoecium
Gynoecium (; ) 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 of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing 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, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ''pi ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ 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 and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the 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 stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
