Polystichum Australiense
''Polystichum australiense'', commonly known as the harsh shield fern is a plant found in New South Wales, Australia. The genus name ''Polystichum'' is derived from Greek ''poly'' - many, and ''stichos -'' rows referring to the many rows of sori. The specific epithet refers to Australia. An unusual feature is the growth of bulbils on end of the fronds. Sori are circular with a brown indusium, the stem is moderately scaly. Fronds are tough, having ultimate segments with distinctly aristate margins. Seen in warmer sites, unlike the related Polystichum proliferum which usually prefers mountain habitats. The type specimen In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached.

Narrabeen
Narrabeen is a beachside suburb in northern Sydney, in the state of New South Wales, Australia. Narrabeen is 23 kilometres north-east of the Sydney central business district, in the local government area of Northern Beaches Council and is part of the Northern Beaches region. This area was named Broken Bay by James Cook as he sailed by. History There are a number of theories on the origin of the name "Narrabeen". The most fanciful is that Narrabeen is named after "narrow beans" which the English in the first year of settlement (1788) found and ate from a vine growing over beach sand. Surgeon White indeed recorded getting ill from such beans but this was well north of Narrabeen, near Broken Bay. The name Narrobine Creek appears in 1801 in records relating to two escaped convicts, and thus the name appears to have been in use before then. Another suggestion is that it derives from an Aboriginal word meaning swan. Surveyor James Meehan placed the name Narabang Narabang Lago ...

Mary Tindale
Mary Douglas Tindale (19 September 1920 – 31 March 2011) was an Australian botanist specialising in pteridology (ferns) and the genera ''Acacia'' and ''Glycine''. Tindale was born in Randwick, New South Wales, the only child of George Harold Tindale and Grace Matilda Tindale. She attended primary school in New York while her father served as British Ambassador to the United States. She returned to Sydney, Australia to attend high school at Abbotsleigh. Tindale earned a B.Sc. in Botany with Honours from Sydney University, as well as a master's degree from the same university. She became Assistant Botanist at the Royal Botanic Gardens, Sydney in 1944 and later served as the Australian Botanical Liaison Officer at the Royal Botanic Gardens, Kew from 1949–1951.

Bulbil
A bulbil (also referred to as bulbel, bulblet, and/or pup) is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them—they have identical genetic material. The formation of bulbils is a form of asexual reproduction, as they can eventually go on to form new stand-alone plants. Although some bulbils meet the botanical criterion to be considered a true bulb, there are a variety of different morphological forms of bulbils, some of which are not considered to be bulbs. Hence the reason for distinction between bulbs and bulbils. For example, some bulbous plant groups, like onions and lilies, produce bulbils in the form of a secondary, small bulb. Onion and lily bulbils meet the botanical criterion to be labeled a true bulb. All bulbils produced by bulbous plants are to be considered bulbs, but not all bulbils are to be consid ...

Sorus
A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. A coenosorus (plural coenosori) is a compound sorus composed of multiple, fused sori. Etymology This New Latin word is from Ancient Greek σωρός (''sōrós'' 'stack, pile, heap'). Structure In lichens and other fungi, the sorus is surrounded by an external layer. In some red algae, it may take the form of depression into the thallus. In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond. In some species, they are protected during development by a scale or film of tissue called the indusium, which forms an umbrella-like cover. Lifecycle significance Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores. As the sporangia mature, the indusium shrivels so that spore release is unimpeded. The sporangia then burst and release the spores. As an aid to identification The shape, arrangemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aristate (botany)
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polystichum Proliferum
''Polystichum proliferum'', commonly known as mother shield fern is an Australian endemic fern. The genus name Polystichum is derived from Greek ''poly'' - many, and ''stichos -'' rows referring to the many rows of sori. The species name is derived from Latin, ''Proli'' – offspring and ''fer -'' bearing referring to the proliferous buds, a prominent feature of the species. Description ''Polystichum proliferum'' is a terrestrial fern that can grow to 130 cm in height. The rhizome and frond bases are covered in persistent scales which are glossy brown with pale edges. Fronds can reach up to 100 cm in length and 30 cm wide, are dark green when mature but lighter and paler when young. Sori (spore clusters) occur in rows on either side of the midrib and are covered with by a large umbrella-like indusium (protective covering) hence the common name “mother shield fern”. Habitat and distribution ''Polystichum proliferum'' is widespread and abundant from sea-lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

The beach is one of eleven beaches located within the territory of the Royal National Park. It is also one of three patrolled beaches in the park, with the Garie Surf Life Saving Club patrolling the beach on weekends and Paid lifeguards from ALS Australian Lifeguard Services patrolling on weekdays during the summer school holidays. History There are two theories of the origins of the name. Garie is a Dharawal The Dharawal people, also spelt Tharawal and other variants, are an Aboriginal Australian people, identified by the Dharawal language. Traditionally, they lived as hunter–fisher–gatherers in family groups or clans with ties of kinship, s ... word meaning "sleepy". The name could also be a deviation of the name of a bushranger called Geaty, who camped here. The beach was used as a location for the 1954 film ''Long John Silver''. Facilities Garie Bea ...
