Racemes
A raceme () or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus '' Brassica''), radish (genus '' Raphanus''), and orchid (genus '' Phalaenopsis'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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.

Actaea Racemosa
''Actaea racemosa'', the black cohosh, black bugbane, black snakeroot, rattle-top, or fairy candle ( syn. ''Cimicifuga racemosa''), is a species of flowering plant of the family Ranunculaceae. It is native to eastern North America from the extreme south of Ontario to central Georgia, and west to Missouri and Arkansas. It grows in a variety of woodland habitats, and is often found in small woodland openings. The roots and rhizomes are used in traditional medicine by Native Americans. Its extracts are manufactured as herbal medicines or dietary supplements. Most dietary supplements containing black cohosh are not well-studied or recommended for safe and effective use in treating menopause symptoms or any disease. Taxonomy The plant species has a history of taxonomic uncertainty. Carl Linnaeus, on the basis of morphological characteristics of the inflorescence and seeds, placed the species into the genus ''Actaea''. This designation was later revised by Thomas Nuttall reclassif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalaenopsis - Feburary 2022 - Sarah Stierch 02
''Phalaenopsis'' (), also known as moth orchids, is a genus of about seventy species of plants in the Family (biology), family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to Asia, New Guinea, and Australia, but mostly occur in Indonesia and the Philippines. Description Orchids in the genus ''Phalaenopsis'' are monopodial epiphytic, sometimes lithophytic Herbaceous plant, herbs with long, coarse roots with pneumatodes (which allow for gaseous exchange of the photosynthetic roots), and short leafy stems hidden by overlapping leaf bases. The leaves are usually arranged in two rows, relatively large and leathery, oblong to elliptic and sometimes succulent. A few to many, small to large, long-lasting, flat, often fragrant flowers are arranged on erect to hanging racemes or panicl ...

Glume
In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grass Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family (biology), family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and spe ...es (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and palea. In grasses, two bracts known as "glumes" form the lowermost organs of a spikelet (there are usually two but one is sometimes reduced; or rarely, both are absent). Glumes may be similar in form to the lemmas, the bracts at the base of each floret. In sedges, by contrast, a glume is a scale at the base of each flower in a spikelet.

Calla
''Calla'' is a genus of flowering plant in the family Araceae, containing the single species ''Calla palustris'' (bog arum, marsh calla, wild calla, squaw claw, and water-arumDickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 62.). Description It is a rhizomatous herbaceous perennial plant growing in bogs and ponds. The leaves are rounded to heart-shaped, long on a petiole, and broad. The greenish-yellow inflorescence is produced on a spadix about long, enclosed in a white spathe. The fruit is a cluster of red berries, each berry containing several seeds. The plant is very poisonous when fresh due to its high oxalic acid content, but the rhizome (like that of ''Caladium'', ''Colocasia'', and ''Arum'') is edible after drying, grinding, leaching and boiling. Taxonomy The genus formerly also included a number of other species, which have now been transferred to the separate genus ''Zant ...

Arisaema Triphyllum
''Arisaema triphyllum'', the Jack-in-the-pulpit, is a species of flowering plant in the arum family Araceae. It is a member of the ''Arisaema triphyllum'' complex, a group of four or five closely related taxa in eastern North America. The specific name ''triphyllum'' means "three-leaved", a characteristic feature of the species, which is also referred to as Indian turnip, bog onion, and brown dragon. Used without qualification, the name ''Arisaema triphyllum'' is ambiguous. For clarity, the qualified name ''Arisaema triphyllum'' sensu stricto (abbreviated s.s.) refers to the species while ''Arisaema triphyllum'' sensu lato refers to the species complex. The latter includes the species (''Arisaema triphyllum'') among its members. ''Arisaema triphyllum'' sensu lato is wide-ranging across eastern North America, from Nova Scotia to Manitoba in eastern Canada, and from Texas to Florida in the southern United States. It is common throughout most of its range. Description The ''Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Description Within the Araceae, species are often rhizomatous or tuberous; many are epiphytic, creeping lianas or vining plants, and the leaves and tissues of the entire plant nearly always contains irritating calcium oxalate crystals or raphides, in varying degrees. The foliage can vary considerably from species to species. The majority of species produce an inflorescence consisting of a spadix (which some compare to a corn cob, in appearance), which is nearly always surrounded ...

Spathe
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. 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 or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of 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 palea (upper bract), while each spikelet (group of florets) has a further pair of bra ...

Spadix (botany)
In botany, a spadix ( ; : spadices , ) is a type of inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known ''Anthurium'' spp. is a typical spadix with a large colorful spathe. In this type of inflorescence, the Peduncle (botany), peduncle is thick, long and fleshy, having small sessile unisexual flowers covered with one or more large green or colourful Bract, bracts (spathe). Spadix inflorescence is found in colocasia, Araceae, aroids, maize and Arecaceae, palms (palms have compound spadix). Plant sexuality, Monoecious aroids have unisexual male and female flowers on the same individual and the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. Typically, the Stigma (botany), stigmas are no longer receptive when pollen is released which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alder
Alders are trees of the genus ''Alnus'' in the birch family Betulaceae. The genus includes about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. Description With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (''Betula'', another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The largest species are red alder (''A. rubra'') on the west coast of North America, and black alder (''A. glutinosa''), native to ...

Pussy Willow
Pussy willow is a name given to many of the smaller species of the genus '' Salix'' (willows and sallows) when their furry catkins are young in early spring. These species include (among many others): * Goat willow or goat sallow ('' Salix caprea''), a small tree native to northern Europe and northwest Asia. * Grey willow or grey sallow ('' Salix cinerea''), a small tree native to northern Europe. * American pussy willow ('' Salix discolor''), native to northern North America. Before the male catkins of these species come into full flower they are covered in fine, greyish fur, leading to a fancied likeness to tiny cats, also known as “ pussies”. The catkins appear before the leaves, and are one of the earliest signs of spring. At other times of year trees of most of these species are usually known by their ordinary names. Cultural traditions Asia The many buds of the pussy willow make it a favourite flower for Lunar New Year. The fluffy white blossoms of the pussy willo ...
