The family Campanulaceae, 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 and Codonopsis lanceolata are eaten as vegetables. Lobelia inflata, L. siphilitica and L. tupa and others have been used as medicinal plants. Campanula rapunculoides may be a troublesome weed, particularly in gardens, while Legousia spp. may occur in arable fields.
Wahlenbergia gloriosa, commonly known as royal bluebell is a perennial herb in the bluebell family Campanulaceae. It has egg-shaped leaves near the base of its stem, linear leaves higher up and usually a single purple flower with a tube-shaped base. The flower is the floral emblem of the Australian Capital Territory.
Wahlenbergia is a genus of around 260 species of flowering plants in the family Campanulaceae. Plants in this genus are perennial or annual herbs with simple leaves and blue to purple bell-shaped flowers, usually with five petals lobes. Species of Wahlenbergia are found on all continents except North America, and on some isolated islands, but the greatest diversity occurs in the Southern Hemisphere.
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.
Argonauta nodosus [previously known as Argonauta nodosa], also known as the knobby or knobbed argonaut, is a species of pelagic octopus. The female of the species, like all argonauts, creates a paper-thin eggcase that coils around the octopus much like the way a nautilus lives in its shell. The shell is usually approximately 150 mm in length, although it can exceed 250 mm in exceptional specimens; the world record size is 292.0 mm. A. nodosus produces a very characteristic shell, which is covered in many small nodules on the ridges across the shell, hence the specific epithet nodosus and common name. These nodules are less obvious or even absent in juvenile females, especially those under 5 cm in length. All other argonaut species have smooth ridges across the shell walls.
The flora of Saint Helena, an isolated island in the South Atlantic Ocean, is exceptional in its high level of endemism and the severe threats facing the survival of the flora. In phytogeography, it is in the phytochorion St. Helena and Ascension Region of the African Subkingdom, in the Paleotropical Kingdom.
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, .
Proterochampsa is an extinct genus of proterochampsid archosauriform from the Late Triassic of South America. The genus is the namesake of the family Proterochampsidae, and the broader clade Proterochampsia. Like other proterochampsids, Proterochampsa are quadruped tetrapods superficially similar in appearance to modern crocodiles, although the two groups are not closely related. Proterochampsids can be distinguished from other related archosauriformes by characters such as a dorsoventrally flattened, triangular skull with a long, narrow snout at the anterior end and that expands transversally at the posterior end, asymmetric feet, and a lack of postfrontal bones in the skull, with the nares located near the midline. Proterochampsa is additionally defined by characters of dermal sculpturing consisting of nodular protuberances on the skull, antorbital fenestrae facing dorsally, and a restricted antorbital fossa on the maxilla. The genus comprises two known species: Proterochampsa barrionuevoi and Proterochampsa nodosa. P. barrionuevoi specimens have been discovered in the Ischigualasto Formation in northwestern Argentina, while P. nodosa specimens have been found in the Santa Maria supersequence in southeastern Brazil. The two species are distinct in several characters, including that P. nodosa has larger, more well-developed nodular protuberances, a more gradually narrowing snout, and a higher occiput than P. barrionuevoi. Of the two, P. nodosa is thought to have less derived features than P. barrionuevoi.
Ficinia nodosa, the knotted club-rush or knobby club-rush, is a rhizomatous perennial in the family Cyperaceae, native to South Africa, Australia, and New Zealand. Widespread in the Southern Hemisphere, Ficinia nodosa grows to between 15 and 220 cm in height. Although it grows best in sandy, salty soil, the plant grows in a wide variety of environments from coastal sand dunes to alpine regions. F. nodosa’s appearance is characterised by dense clusters of long green stems topped with small, rounded flowers often remaining throughout the year.
Ficinia is a genus of tufted or rhizomatous sedges in the family Cyperaceae. There are around 70 recognised species in Africa, four species that occur in New Zealand and a single species Ficinia nodosa that occurs in Australia.
Leucoptera is a small genus of flowering plants in chamomile tribe within the daisy family.
Cymodocea nodosa is a species of seagrass in the family Cymodoceaceae and is sometimes known as little Neptune grass. As a seagrass, it is restricted to growing underwater and is found in shallow parts of the Mediterranean Sea and certain adjoining areas of the Atlantic Ocean.
Melaleuca nodosa, commonly known as the prickly-leaved paperbark, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. It is a shrub or small tree with narrow, sometimes needle-like leaves and profuse heads of yellow flowers as early as April or as late as January.
Wahlenbergia multicaulis is a small herbaceous plant in the family Campanulaceae native to Australia.
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.
Roger Charles Carolin is a botanist, pteridologist and formerly an associate professor at Sydney University. He was appointed as a lecturer in botany at the University of Sydney in 1955 earned a Ph.D from Sydney University in 1962 with a thesis on the floral morphology of the campanales, and retired as an associate professor in 1989.
Wahlenbergia tenella is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.
Wahlenbergia loddigesii is a herbaceous plant in the family Campanulaceae native to the southern Cape regions of South Africa.
