Maianthemum Tubiferum
''Maianthemum'' includes the former genus ''Smilacina'' and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds. Vegetative ; Rhizomes and roots Rhizomes are persistent and have scale leaves. They can be sympodial; spreading and thread-like, or cylin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Maianthemum Racemosum
''Maianthemum racemosum'', the treacleberry, feathery false lily of the valley, false Solomon's seal, Solomon's plume or false spikenard, is a species of flowering plant native to North America. It is a common, widespread plant with numerous common names and synonyms, known from every US state except Hawaii, and from every Canadian province and territory (except Nunavut and the Yukon), as well as from Mexico. Description It is a woodland herbaceous perennial plant growing to tall, with 7–12 alternate, oblong-lanceolate leaves long and broad. The leaf bases are rounded to clasping or tapered, sometimes with a short petiole. The leaf tips are pointed to long-tipped. Seven to 250 small flowers are produced on a panicle that has well-developed branches. Each flower has six white tepals long and is set on a short pedicel usually less than 1 mm long. Blooming is mid-spring with fruiting by early summer. The plants produce fruits that are rounded to 3-lobed and green with c ...

Tepals
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 similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Maianthemum Bifolium
''Maianthemum bifolium'' (false lily of the valley or May lily) is often a localized common rhizomatous flowering plant, native from western Europe (including Britain''New Flora of The British Isles'', Clive Stace) east to Siberia, China and Japan. Non-flowering stems usually have only one waxy leaf, but on flowering plants there is one basal leaf that withers away before flowering, and two stem leaves produced alternately up the 10–20 cm tall stems, which are topped off with many star-shaped white flowers. The leaves are heart to triangular, 3–8 cm long and 2–5 cm broad, with small fine hairs on the veins. The flowers have four tepals, four stamens and have two chambers in the pistil; flowering is in mid spring to early summer. This species, along with ''Maianthemum canadense'' and ''Maianthemum dilatatum'' are the only four-tepaled species. One to two seeds are produced in round berries that are speckled red when immature and redden with age. This species is ...

Trimerous
Merosity (from the greek "méros," which means "having parts") refers to the number of component parts in a distinct whorl of a plant structure. The term is most commonly used in the context of a flower where it refers to the number of sepals in a whorl of the calyx, the number of petals in a whorl of the corolla, the number of stamens in a whorl of the androecium, or the number of carpels in a whorl of the gynoecium. The term may also be used to refer to the number of leaves in a leaf whorl. The adjective ''n''-merous refers to a whorl of ''n'' parts, where ''n'' is any integer greater than one. In nature, five or three parts per whorl have the highest frequency of occurrence, but four or two parts per whorl are not uncommon. Be aware that two consecutive whorls of dimerous petals are often mistaken for tetramerous petals. If all of the whorls in a given floral arrangement have the same merosity, the flower is said to be isomerous, otherwise the flower is anisomerous. For exa ...

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Actinomorphic
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged. Actinomorphic Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on. It may or may not be possible to divide the flower into symmetrical halves by the same number of longitudinal planes passing through the axis: Oleander is an example of a flower without such mirror planes. Actinomorphic flowers are also called radially symmetrical or regular flowers. Other examples of actinomorphic flowers are the lily (''Lilium'', Liliaceae) and the buttercup (''Ranunculus'', Ranunculaceae). Zygomorphic Zygomorp ...

Maianthemum Dilatatum
''Maianthemum dilatatum'' (snakeberry, two-leaved Solomon's seal or false lily of the valley) is a common rhizomatous perennial flowering plant that is native to western North America from northern California to the Aleutian islands, and Asia across the Kamchatka Peninsula, Japan, and Korea. It grows in coastal temperate rainforests, and is often the dominant groundcover plant in Sitka Spruce forests. Description The plant produces an erect, unbranched flower stem, occasionally to 40 centimeters in height, but typically much shorter. A non-flowering shoot bears one smooth, waxy, shiny leaf up to 10 centimeters long and 5 to 8 cm broad, hence its scientific name (''dilatatum'' means 'broad'). The leaf is oval in shape with a heart-shaped base. The inflorescence is an erect raceme with star-shaped white flowers. They each have four tepals and four stamens. After fertilization the fruit produced is a berry 6 millimeters in diameter. The berry is speckled red when immature and ...

Leaves
A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthesis, photosynthetic 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. 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, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
