Sir Joseph Dalton Hooker was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For 20 years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science.
Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.
Microseris scapigera is a yellow-flowered daisy, a perennial herb, found in New Zealand and Australia. It is the only New Zealand species of Microseris, and one of three Australian species along with Microseris lanceolata and Microseris walteri. It is classified in a group of plants, the tribe Cichorieae, that includes chicory and dandelion.
Ruhlandiella is a genus of fungi within the family Pezizaceae. Ruhlandiella species are exothecial hypogeous fungi, which are essentially truffles that lack the outer layer or peridium. Ruhlandiella species are widely distributed in Nothofagaceae forests in South America and near Eucalyptus or Melaleuca plants in Australia, North America, and Europe.
Adenochilus, commonly known as gnome orchids is a genus of two species of flowering plants in the orchid family Orchidaceae, one endemic to New Zealand and the other to Australia. Both species have a long, horizontal, underground rhizome with a single leaf on the flowering stem and a single resupinate flower with its dorsal sepal forming a hood over the labellum and column.
Austropaxillus is a genus of fungi in the family Serpulaceae, containing nine species found in Australia, New Zealand and South America.
Herpolirion is a genus of perennial herbs in the family Asphodelaceae, subfamily Hemerocallidoideae. The sole species is Herpolirion novae-zelandiae, commonly known as sky lily. It is native to New Zealand as well as the states of New South Wales, Victoria and Tasmania in Australia.
Plectania rhytidia is a species of fungus in the family Sarcosomataceae. Originally described under the name Peziza rhytidia by Miles Joseph Berkeley in 1855, the species was transferred to Plectania by mycologists John Axel Nannfeldt and Richard Korf in 1957.
The Flora Antarctica, or formally and correctly The Botany of the Antarctic Voyage of H.M. Discovery Ships Erebus and Terror in the years 1839–1843, under the Command of Captain Sir James Clark Ross, is a description of the many plants discovered on the Ross expedition, which visited islands off the coast of the Antarctic continent, with a summary of the expedition itself, written by the British botanist Joseph Dalton Hooker and published in parts between 1844 and 1859 by Reeve Brothers in London. Hooker sailed on HMS Erebus as assistant surgeon.
The Flora Novae-Zelandiae is a description of the plants discovered in New Zealand during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1853 and 1855. Hooker sailed on HMS Erebus as assistant surgeon. It was the third in a series of four Floras in the Flora Antarctica, the others being the Botany of Lord Auckland's Group and Campbell's Island (1843–45), the Botany of Fuegia, the Falklands, Kerguelen's Land, Etc. (1845–1847), and the Flora Tasmaniae (1853–1859). They were "splendidly" illustrated by Walter Hood Fitch.
The Flora Tasmaniae is a description of the plants discovered in Tasmania during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1855 and 1860. Hooker sailed on HMS Erebus as assistant surgeon. Written in two volumes, it was the last in a series of four Floras in the Flora Antarctica, the others being the Botany of Lord Auckland's Group and Campbell's Island (1843–1845), the Botany of Fuegia, the Falklands, Kerguelen's Land, Etc. (1845-47), and the Flora Novae-Zelandiae (1851–1853). They were "splendidly" illustrated by Walter Hood Fitch.
Myosotis capitata is a species of flowering plant in the family Boraginaceae, endemic to the Campbell and Auckland Islands of New Zealand. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial and erect, and have ebracteate inflorescences and blue corollas. It is one of two native species of Myosotis in the New Zealand subantarctic islands, the other being M. antarctica, which can also have blue corollas.
Dracophyllum menziesii, commonly known as pineapple scrub, is a species of shrub endemic to the South and Stewart Islands of New Zealand. In the heath family Ericaceae, it inhabits mountain slopes and cliffs from sea level up to 1,500 m (4,921 ft) and reaches a height of 0.5–1 m (1.6–3.3 ft). A 2017 assessment using the New Zealand Threat Classification System classified it as "Not Threatened," giving it an estimated population upwards of 100,000.
Myosotis albiflora is a species of flowering plant in the family Boraginaceae, native to southern Chile and Argentina. This species was described by Joseph Banks and Daniel Solander in Joseph Dalton Hooker's 19th century work Flora Antarctica. Plants of this species of forget-me-not are perennial and have white corollas. It is one of two native species of Myosotis in southern South America, the other being M. antarctica.
Myosotis lyallii is a species of flowering plant in the family Boraginaceae, endemic to New Zealand. Joseph Dalton Hooker described the species in 1853. Plants of this species of forget-me-not are perennial with a prostrate habit, bracteate or partially-bracteate inflorescences, and white corollas.
Myosotis lyalliisubsp. lyallii is a subspecies of flowering plant in the family Boraginaceae, endemic to the South Island of New Zealand. Joseph Dalton Hooker described M. lyallii in 1853. Plants of this subspecies of forget-me-not are perennial with a prostrate habit, bracteate or partially-bracteate inflorescences, and white corollas, usually with exserted anthers.
Mastodia is a genus of lichen-forming fungi in the family Verrucariaceae. It has six species. The genus was circumscribed in 1847 by Joseph Dalton Hooker and William Henry Harvey. The type species, Mastodia tessellata, is a bipolar, coastal lichen. It forms a symbiotic association with the macroscopic genus Prasiola; this is the only known lichen symbiosis involving a foliose green alga. Studies suggest that throughout its geographic range, the lichen comprises two fungal species and three algal lineages that associate.
Puccinellia stricta is a species of grass known by the common names Australian saltmarsh grass, and Marshgrass. It was first described by Joseph Dalton Hooker in 1853 as Glyceria stricta from a specimen collected at Akaroa, but was assigned to the genus, Puccinellia, in 1930 by Carl Hilding Blom. It is native to New Zealand and Australia, where it is found in Western Australia, South Australia, Victoria and Tasmania.
Paurocotylis pila is a saprobic, truffle-like ascomycete from the genus Paurocotylis. It is native to New Zealand and Australia and is naturalised in the United Kingdom.
Pseudocyphellaria granulata is a species of foliose lichen in the family Lobariaceae. It is found in South America and New Zealand.
