Portulaca Filsonii
''Portulaca filsonii'' (common names - Sedopsis, Pink Rock-wort) is a plant in the Portulacaceae family, endemic to central Australia in the Northern Territory. It was first described by James Hamlyn Willis in 1975 from a specimen collected in Kings Canyon. The holotypeMEL 501441and isotypeMEL 501455 were both collected by Willis in 1966. The name accepted by the Council of Heads of Australasian Herbaria is the later name of ''Sedopsis filsonii'', created as a new combination by Willis in 1977. The species epithet, ''filsonii'', honours Rex Bertram Filson. ''Portulaca filsonii'' is listed as "Near Threatened" under the TPWCA Act. Description ''Portulaca filsonii'' is a prostrate, succulent perennial plant. It has a swollen root, and its leaves are opposite. The flowers have a tubular corolla with four pink spreading lobes. There are two partially fused sepals. References External links ''Sedopsis filsonii'' occurrence datafrom the Australasian Virtual Herbarium ...

Portulacaceae
The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus ''Portulaca''. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals. The APG II system (2003; unchanged from the APG system of 1998) assigns it to the order Caryophyllales in the clade core eudicots. In the APG III system, several genera were moved to the Montiaceae, Didiereaceae, Anacampserotaceae and Talinaceae, thus making the family monotypic and only containing the genus ' ...

Kings Canyon (Northern Territory)
Kings Canyon is a canyon in the Northern Territory of Australia located at the western end of the George Gill Range about southwest of Alice Springs and about south of Darwin within the Watarrka National Park. Description The walls of Kings Canyon are over 100 metres high, with Kings Creek at the bottom. Part of the gorge is a sacred Aboriginal site and visitors are discouraged from leaving the walking tracks. Three walks exist at Kings Canyon. The two km (return) and approximately one-hour Kings Creek Walk traces the bottom of the gorge. At the end of the walk is a platform, with views of the canyon walls above. The six km (loop) Kings Canyon Rim Walk traces the top of the canyon and takes three to four hours to complete. A steep climb at the beginning of the walk, which locals call "Heartbreak Hill" (or "Heart Attack Hill", due to its steepness), takes visitors up to the top, with views of the gorge below and of the surrounding landscape.

Plants Described In 1975
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
