Wahlenbergia
''Wahlenbergia'' is a genus of around 260 species of flowering plants in the Family (biology), family Campanulaceae. Plants in this genus are Perennial plant, perennial or Annual plant, annual Herbaceous plant, herbs with simple leaves and blue to purple bell-shaped flowers, usually with five petals lobes. Species of ''Wahlenbergia'' are native to environments on all continents except North America, and on some isolated islands, but the greatest diversity occurs in the Southern Hemisphere. Description Plants in the genus ''Wahlenbergia'' are annual or perennial herbs, rarely shrubs, and sometimes have rhizomes. The stems are erect, circular in cross section and have simple leaves. The leaves decrease in size up the stem and usually have small scattered teeth on their edges. The flowers are borne on the end of the stems, either singly or arranged in a Inflorescence#Determinate or cymose, cyme. There are five sepals that remain until the fruiting stage. The petals are blue to purple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wahlenbergia Capensis
''Wahlenbergia capensis'', commonly known as the Cape bluebell, is a plant in the family ''Campanulaceae'' and is native to the Cape Province but has been introduced to Australia. It is an annual herb with up to four greenish blue, bell-shaped flowers with spreading petal lobes.

Wahlenbergia Stricta
''Wahlenbergia stricta'', the Australian bluebell, tall bluebell or austral bluebell, is an Australian wildflower from the Campanulaceae family. It is considered the most commonly encountered of the Wahlenbergias. It is found in all Australian states but not the Northern Territory. It is often seen growing by the side of the road, enjoying the extra runoff. ''Wahlenbergia stricta'' is a perennial herb flowering mainly in spring or summer with pale blue bell-like flowers. The leaves are long and linear, long. The five-petalled flowers are erect on long, slender stems and about in diameter. It forms thin, carrot shaped tubers. Cultivation Australian bluebells are generally easily propagated by division or root cutting. The seed is a very fine, black powder. It germinates readily in a few weeks and is best directly sown into tubes or cells as the seed and plant are very small and hard to separate and prick out. There are a number of common cultivars, including various shade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wahlenbergia Roxburghii
''Wahlenbergia roxburghii'', the Roxburgh bellflower or dwarf cabbage tree, is an extinct member of a group of four species of ''Wahlenbergia'' once known from the island of Saint Helena, in the South Atlantic Ocean. It was last seen by naturalist John Charles Melliss in 1872. William Roxburgh recorded it in the thick forests on the south face of Diana's Peak. De Candolle notes it in dense woods around Diana's Peak and Halley's Mount. Burchell notes it 'On Sandy Bay ridge near Taylor's. Flowering: probably August to March. It was exceedingly rare in Meliss's time, it is not in his book as he had not found it. It was probably the increase of Phormium tenax planting on the ridge that pushed ''Wahlenbergia roxburghii'' into final extinction. It is an example of one of the early extinctions of Saint Helena plants as a result of human activity, with a history similar to that of the stringwood (''Acalypha rubrinervis''), (see List of extinct plants).

Campanulaceae Genera
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera '' Campanula'' (bellflower), '' Lobelia'', and '' Platycodon'' (balloonflower). '' Campanula rapunculus'' (rampion or r. bellflower) and '' Codonopsis lanceolata'' are eaten as vegetables. '' Lobelia inflata'' (indian tobacco), '' L. siphilitica'' and '' L. tupa'' (devil's tobacco) and others have been used as medicinal plants. '' Campanula rapunculoides'' (creeping bellflower) may be a troublesome weed, particularly in gardens, while ''Legousia'' spp. may occur in arable fields. Most current classifications include the segregate family Lobeliaceae in Campanulaceae as subfamily Lobelioideae. A third subfamily, Cyphioideae, includes the genus '' Cyphia'', and sometimes also the genera '' Cyphocarpus'', '' Nemacladu ...

Göran Wahlenberg
Georg (Göran) Wahlenberg (1 October 1780 – 22 March 1851) was a Swedish naturalist. He was born in Kroppa, Värmland County. Wahlenberg matriculated at Uppsala University in 1792, received his doctorate in Medicine in 1806, was appointed ''botanices demonstrator'' in 1814, and professor of medicine and botany in 1829, succeeding Carl Peter Thunberg. He was the last holder of the undivided chair that in the previous century had been held by Linnaeus. After his death in 1851, the chair was divided into more delimited professorships, and botany became the main duty of the borgströmian professorship, at the time held by Elias Fries. Wahlenberg made his main work in the field of plant geography and published, among other things the ''Flora lapponica'' (1812) and other works on the plant world of northernmost Sweden. He was among the first major scholars to contribute to the plant taxonomy and geography of the High Tatras in the Habsburg monarchy where he carried out re ...

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 (multicarpellary) 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 ...

Saint Helena
Saint Helena (, ) is one of the three constituent parts of Saint Helena, Ascension and Tristan da Cunha, a remote British overseas territory. Saint Helena is a volcanic and tropical island, located in the South Atlantic Ocean, some 1,874 km (1,165 miles) west of the mainland of the continent of Africa, with the Southern African nations of Angola and Namibia on its southeastern coast being the closest nations geographically. The island is around west of the coast of southwestern South Africa, and east of the major seaport city of Rio de Janeiro, Brazil in South America. Saint Helena measures about and had a population of 4,439 in the 2021 census. It was named after Helena, mother of Constantine I, Saint Helena (AD c.246/248–330), influential mother of the famous Roman Emperor Constantine the Great, Saint Constantine I the Great. (A.D 272–337, reigned 306–337), of the ancient Roman Empire. It is one of the most remote major islands in the world and was uninhabited unt ...

Australasia
Australasia is a subregion of Oceania, comprising Australia, New Zealand (overlapping with Polynesia), and sometimes including New Guinea and surrounding islands (overlapping with Melanesia). The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific ( Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colon ...
