Aquilegia Paui
''Aquilegia paui'' is a species of perennial flowering plant in the genus ''Aquilegia'' (columbines) in the family Ranunculaceae. The species has an extremely limited range, narrowly endemic only to the mountains of Ports de Tortosa-Beseit, a massif in the Province of Tarragona in Catalonia, northeastern Spain. Due to a herbarium filing error, and the absence of observations of ''A. paui'' from 1920 until 1999, the species was long considered a subspecies or synonym of ''Aquilegia vulgaris''. Growing up to tall, the species blooms in May and June. The flowers are bluish-purple with pale or whitish petals. The species has a small population that, as of 2011, numbered about 2,000 individuals spread across four subpopulations. Human activity, predation by the native Southeastern Spanish ibex, and poor genetic diversity have been cited as risks to the continued survival of ''A. paui''.

Font Quer
Pius Font i Quer (1888 – 1964) was a Catalan botanist, pharmacist and chemist. Biography Born in 1888, in Lleida, Font organized the Institut Botànic de Barcelona and founded Jardí Botànic in this city. In 1911 he joined the Health Military Corporation, in which he was given the military rank of ''tinent coronel farmacèutic''. He was on a botanic expedition in Albarracín (Aragon) with his fellowship when the Francisco Franco's 1936 ''coup d'état'' failed and began the Spanish Civil War. When he want back to Barcelona, he had to go through the war front; for this the reason he was accused of being a member of the military rebellion and lost all his honours, which made continuation of his scientific work difficult. Font was president of the Institució Catalana d'Història Natural (1931–1934), president of the Institut d'Estudis Catalans in 1958 and of the Société Botanique at Geneve, honour vice president of the International Botany Congresses at Paris (1954) a ...

Trichome
Trichomes (; ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be Leaf#Surface, pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell (biology), cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as ''Spirulina (dietary supplement), Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar
Nectar is a viscous, sugar-rich liquid produced by Plant, plants in glands called nectaries, either within the flowers with which it attracts pollination, pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal Mutualism (biology), mutualists, which in turn provide plant defense against herbivory#Indirect defenses, herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverfly, hoverflies, wasps, bees, butterfly, butterflies and moths, hummingbirds, honeyeaters and Bat#Fruit and nectar, bats. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of predacious or Parasitoid wasp, parasitoid wasps (e.g., the social wasp species ''Apoica flavissima'') rely on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar Spur
A nectar spur is a hollow extension of a part of a flower. The spur may arise from various parts of the flower: the sepals, petals, or hypanthium, and often contain tissues that secrete nectar Nectar, (nectaries). Nectar spurs are present in many clades across the Flowering plant, angiosperms, and are often cited as an example of List of examples of convergent evolution, convergent evolution. Taxonomic significance Spur length can be an important diagnostic character for taxonomy, useful in species identification. For example, Yadon's piperia can be distinguished from ''Platanthera elegans'', an extremely similar species in section ''Piperia'' (Orchidaceae), by the unusually short length of its spur. Ecology and evolution The presence of nectar spurs in a clade of plants is associated with evolutionary processes such as coevolution (two-sided evolution) and pollinator shifts (one-sided evolution). Like variations in floral tube length, variation in nectar spur length has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real Jardín Botánico De Madrid
Real Jardín Botánico de Madrid (Spanish language, Spanish for "Royal Botanical Garden of Madrid") is an botanical garden in Madrid (Spain). The public entrance is located at Plaza de Murillo, next to the Museo del Prado, Prado Museum. History The garden was founded on October 17, 1755, by King Ferdinand VI of Spain, Ferdinand VI, and installed in the Orchard of Migas Calientes, near what today is called Puerta de Hierro, on the banks of the Manzanares River. It contained more than 2,000 plants collected by José Quer y Martínez, botanist and surgeon. In 1774 King Charles III of Spain, Charles III ordered the garden moved to its current location on the Paseo del Prado. This new site opened in 1781. Inside an area defined by wrought iron fencing, the design by architects Francesco Sabatini and Juan de Villanueva organized the garden into three tiered terraces, arranging plants according to the method of Linnaeus. Its mission was not only to exhibit plants, but also to teach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpel
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 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 stame ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
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 o ...

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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaucous
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by i ...

Glabrous
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
