Cycas conferta is a species of cycad. It is native to rocky areas of the Northern Territory in Australia, including Kakadu National Park. [1]
Cycas is a genus of plants belonging to a very ancient lineage, the Cycadophyta, which are not closely related to palms, ferns, trees or any other modern group of plants. They are evergreen perennials which achieved their maximum diversity in the Jurassic and Cretaceous periods, when they were distributed almost worldwide. At the end of the Cretaceous, when the non-avian dinosaurs became extinct, so did most of the cycas in the Northern Hemisphere.
Cycas revoluta, is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant.
Sago palm is a common name for several plants which are used to produce a starchy food known as sago. Sago palms may be "true palms" in the family Arecaceae, or cycads with a palm-like appearance. Sago produced from cycads must be detoxified before consumption. Plants called sago palm include:
The Cruising Yacht Club of Australia (CYCA), established in 1944 in Rushcutters Bay, inner-east Sydney. The Club is known as one of Australia's premier yacht clubs, and is acknowledged as one of the leaders in ocean racing in the country. However, the club is best known as the host of the famous Sydney to Hobart Yacht Race.
Banksia conferta, commonly known as the glasshouse banksia, is a species of shrub that is endemic to eastern Australia. It has rough, bark on the trunk, elliptic to egg-shaped leaves arranged in whorls, crowded yellow flowers in a cylindrical spike later forming a relatively large number of follicles.
Cycas beddomei is a species of cycad in the genus Cycas, native to India, where it is confined to a small area of Andhra Pradesh state in the Tirumala Hills in scrubland and brush covered hills.
Banksia ser. Salicinae is a valid botanic name for a series of Banksia. First published by Carl Meissner in 1856, the name has had three circumscriptions.
"The genus Banksia L.f. (Proteaceae)" is a 1981 monograph by Alex George on the taxonomy of the plant genus Banksia. Published by the Western Australian Herbarium as Nuytsia3(3), it presented George's taxonomic arrangement of Banksia, the first major taxonomic revision of the genus since George Bentham published his arrangement in Flora Australiensis in 1870.
This is a timeline of developments in knowledge and understanding of the Australian plant genus Banksia:
Banksia penicillata is a species of shrub that is endemic to a restricted area of New South Wales. It has smooth bark, serrated, elliptic to egg-shaped leaves, green to bluish flower buds, later yellow flowers in a cylindrical spike, and later still, up to one hundred narrow elliptical follicles in each spike, surrounded by the remains of the flowers.
Banksia densa is a species of column-like shrub that is endemic to Western Australia. It has deeply serrated to pinnatifid leaves, creamy yellow flowers in heads of up to seventy-five, and hairy follicles.
Kevin Thiele and Pauline Ladiges taxonomic arrangement of Banksia, published in 1996, was a novel taxonomic arrangement that was intended to align the taxonomy of Banksia more closely with the phylogeny that they had inferred from their cladistic analysis of the genus. It replaced Alex George's 1981 arrangement, but most aspects were not accepted by George, and it was soon replaced by a 1999 revision of George's arrangement. However some herbaria have continued to follow Thiele and Ladiges on some points.
Alex George's taxonomic arrangement of Banksia was the first modern-day arrangement for that genus. First published in 1981 in the classic monograph The genus Banksia L.f. (Proteaceae), it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was overturned in 1996 by Kevin Thiele and Pauline Ladiges, but restored by George in 1999. A recent publication by Austin Mast and Kevin Thiele suggests that it will soon be overturned again.
Cycas circinalis, also known as the queen sago, is a species of cycad known in the wild only from southern India. Cycas circinalis is the only gymnosperm species found among native Sri Lankan flora.
Banksia conferta subsp. conferta is a subspecies of Banksia conferta. As an autonym, it is defined as encompassing the type material of the species. It grows only in Queensland between the Lamington Plateau and the Glass House Mountains.
Banksia densa var. parva is a variety of Banksia densa. It was known as Dryandra conferta var. parva until 2007, when Austin Mast and Kevin Thiele sunk all Dryandra into Banksia. Since there was already a Banksia named Banksia conferta, Mast and Thiele had to choose a new specific epithet for D. conferta and hence for this variety of it. As with other members of Banksia ser. Dryandra, it is endemic to the South West Botanical Province of Western Australia.
Banksia densa var. densa is a variety of Banksia densa. It was known as Dryandra conferta var. conferta until 2007, when Austin Mast and Kevin Thiele sunk all Dryandra into Banksia. Since the name Banksia conferta had already been used, Mast and Thiele had to choose a new specific epithet for D. conferta and hence for this variety of it. As with other members of Banksia ser. Dryandra, it is endemic to the South West Botanical Province of Western Australia. As an autonym, it is defined as encompassing the type material of the species.
Juniperus conferta is a species of juniper, native to Japan, where it grows on sand dunes. It is often treated as a variety or subspecies of Juniperus rigida.
