Spathe
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant 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 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 (adaxial) and lower ( 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 to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Yellow-rattle Close 700
''Rhinanthus minor'', known as yellow rattle, is a herbaceous wildflower in the genus ''Rhinanthus'' in the family Orobanchaceae (the broomrapes). It has circumpolar distribution in Europe, Russia, western Asia, and northern North America. An annual plant, yellow rattle grows up to tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds. The preferred habitat of ''Rhinanthus minor'' is dry fields or meadows; it tolerates a wide range of soil types. It flowers in the summer between May and September. It is hemiparasitic, notably on Poaceae (grasses) and Fabaceae (legumes), and farmers consider it to be a pest, as it reduces grass growth. Yellow rattle is used to create or restore wildflower meadows, where it maintains species diversity by suppressing dominant grasses and the recycling of soil nutrients. The seed is sown thinly onto grassland from August to November—to germinate the following spring, the seeds need to remai ...

Euphorbia
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and ''Senecio''. ''Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant (''Euphorbia milii''). ...

Cornus Florida
''Cornus florida'', the flowering dogwood, is a species of flowering tree in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure. Classification The flowering dogwood is usually included in the dogwood genus ''Cornus'' as ''Cornus florida'' L., although it is sometimes treated in a separate genus as ''Benthamidia florida'' (L.) Spach. Less common names for ''C. florida'' include American dogwood, Florida dogwood, Indian arrowwood, Cornelian tree, white cornel, white dogwood, false box, and false boxwood. Two subspecies are generally recognized: Description Flowering dogwood is a small deciduous tree growing to high, often wider than it is tall when mature, with a trunk diameter of up to . A ...

Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

Erigeron Peregrinus
''Erigeron peregrinus'' is a North American species of flowering plants in the family Asteraceae known by the common name wandering fleabane. ''Erigeron peregrinus'' is native to northwestern North America from Alaska to Oregon. Some populations from farther south (California, Colorado, etc.) were formerly considered as belonging to this species, but they have now either been moved to other taxa or recognized as distinct species. ''Erigeron peregrinus'' is a perennial herb up to 70 centimeters (28 inches) in height, spreading by means of underground rhizomes. It has hairless to hairy leaves reaching up to 10 centimeters long at the base of the branching stem, getting smaller higher up on the stem. The plant usually produces only one flower head per stem, each with 30–80 blue, purple, pink, or white ray florets surrounding numerous disc florets. Flowers bloom July to August. Its habitats include stream banks, bogs, and moist mountain meadows. ;Varieties *''Erigeron peregrinus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ananas Bracteatus
The pineapple (''Ananas comosus'') is a tropical plant with an edible fruit; it is the most economically significant plant in the family Bromeliaceae. The pineapple is indigenous to South America, where it has been cultivated for many centuries. The introduction of the pineapple to Europe in the 17th century made it a significant cultural icon of luxury. Since the 1820s, pineapple has been commercially grown in greenhouses and many tropical plantations. Pineapples grow as a small shrub; the individual flowers of the unpollinated plant fuse to form a multiple fruit. The plant is normally propagated from the Offset (botany), offset produced at the top of the fruit, or from a side shoot, and typically matures within a year. Botany The pineapple is a herbaceous plant, herbaceous perennial, which grows to tall, although sometimes it can be taller. The plant has a short, stocky stem with tough, waxy leaves. When creating its fruit, it usually produces up to 200 flowers, although s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphorbia Milii
''Euphorbia milii'', the crown of thorns, Christ plant, or Christ thorn, is a species of flowering plant in the spurge family Euphorbiaceae, native to Madagascar. The species name commemorates Baron Milius, once Governor of Réunion, who introduced the species to France in 1821. It is imagined that the species was introduced to the Middle East in ancient times, and legend associates it with the crown of thorns worn by Christ. It is commonly used as an ornamental houseplant that can be grown in warmer climates. The common name is due to the thorns and deep red bracts referring to the crown thorn Jesus had to wear during his crucifixion and his blood. Description It is a woody succulent subshrub or shrub growing to tall, with densely spiny stems. The straight, slender spines, up to long, help it scramble over other plants. The fleshy, green leaves are found mainly on new growth, and are up to long and broad. The flowers are small, subtended by a pair of conspicuous petal-li ...

Banana
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus ''Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – ''Musa acuminata'' and ''Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ''Musa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bougainvillea Glabra
''Bougainvillea glabra'', the lesser bougainvillea or paperflower, is the most common species of bougainvillea used for bonsai. The epithet 'glabra' comes from Latin and means "bald". Description It is an evergreen, climbing shrub with thick, thorny stems and drooping branches that are glabrous or sparsely hairy. The leaves have a stem. The leaf blade is ovate to ovate-lanceolate, pointed or briefly pointed, 5 to 13 centimeters long and 3 to 6 centimeters wide, sparsely fluffy hairy on the underside and bald on the top. The leaf-like bracts are purple, oblong or elliptical, pointed, long and about wide. They tower over the flowers. These grow individually in pairs or in groups of three on flower stems about 3.5 millimeters long. The crown tube is greenish, clearly angled, about 2 centimeters long, sparsely downy hairy, ribbed and points away from the flower stalk. The tip is lobed five times and forms a short, spread, white or yellowish hem. The six to eight stamens have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
