Operculum (botany)
In botany, an operculum () or calyptra () is a cap-like structure in some flowering plants, mosses, and fungus, fungi. It is a covering, hood or lid, describing a feature in plant morphology. Flowering plants In flowering plants, the operculum, also known as a calyptra, is the cap-like covering or "lid" of the flower or fruit that detaches at maturity. The operculum is formed by the fusion of sepals and/or petals and is usually shed as a single structure as the flower or fruit matures. The name is also used for the capping tissue of roots, the root cap. In eucalypts, (including ''Eucalyptus'' and ''Corymbia'' but not ''Angophora'') there may be two opercula - an outer operculum formed by the fusion of the united sepals and an inner operculum formed by the fusion of the sepals. In that case, the outer operculum is shed early in the development of the bud leaving a scar around the bud. In those species that lack an outer operculum, there is no bud scar. The inner operculum is sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudall River
The Rudall River ( Wanman: ''Karlamilyi'') is an ephemeral river in the Pilbara region of Western Australia. The entire length of the river is located within the boundaries of the Karlamilyi National Park, which straddles the Little Sandy Desert (LSD) and the Great Sandy Desert (GSD). The headwaters of the river lie in the LSD below the Watrara Range near Island Hill, and it flows eastward into the GSD until it discharges into Lake Dora. The river is unique in the region as it is a major watercourse with reliable water sources and many permanent pools. The river has a total of nine tributaries, including Watrara Creek, Rooney Creek, Poonemerlarra Creek and Dunn Creek. The river was named by the explorer Frank Hann in 1896 after the surveyor William Frederick Rudall whom he met in the area while Hann was prospecting and Rudall was searching for men missing from the Calvert Expedition. The traditional owners Native title is the designation given to the common law doctrine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias.

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
