''Notelaea'' is a genus of flowering plants in the family Oleaceae. It includes 21 species native to eastern Australia and Tasmania, New Zealand, the Norfolk Islands, New Caledonia, and the Hawaiian Islands. Plants in the genus ''Notelaea'' are shrubs or small trees with leaves arranged in opposite pairs, flowers arranged in racemes in leaf axils with small sepals and 2 pairs of petals joined in pairs, 2 stamens and an ovary with 2 ovules with a 2-lobed stigma. Description Plants in the genus ''Notelaea'' are shrubs or small trees with simple, leathery leaves arranged in opposite pairs. The flowers are bisexual arranged in racemes in leaf axils, sometimes reduced to sessile clusters. The sepals are small, joined at the base with 4 triangular lobes and the 4 petals are broadly egg-shaped and joined in pairs at the base of the stamens. Each flower has 2 stamens with a flask-shaped ovary with 2 locules each with 2 ovules. The style is short with a 2-lobed stigma and the fruit i ...

Notelaea Apetala
''Notelaea apetala'' is a small tree native to northeastern New Zealand and to Norfolk Island. The common names in New Zealand are coastal maire or broad-leaved maire. On Norfolk Island, the common name is ironwood. The species name ''apetala'' refers to the lack of petals on the flowers. Distribution In New Zealand ''N. apetala'' grows on the North Island mainland on rocky headlands around Whangarei Heads and at the Bay of Islands. It is also found on northern offshore islands including the Hen and Chickens Islands, Great Barrier Island, Little Barrier Island, and the Poor Knights Islands. It tends to be rare on islands with rats. On Norfolk Island, it is common on Mt Pitt, and in forested areas generally, but is less common elsewhere. Description ''Notelaea apetala'' is shrub or tree up to 6 m tall, with smooth, shiny dark green leaves 4.5 to 12 cm long and 1.5 to 4 cm wide. Juvenile leaves are larger, up to 14 cm long by 8.5 cm wide. The leaves are ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oleaceae
Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct.Peter S. Green. 2004. "Oleaceae". pages 296-306. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. The extant genera include ''Cartrema'', which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. . The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, as ...

Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

Osmanthus
''Osmanthus'' is a genus of about 30 species of flowering plants in the family Oleaceae. Most of the species are native to eastern Asia (China, Japan, Korea, Southeast Asia, the Himalayas, etc.) with a few species from the Caucasus, New Caledonia, and Sumatra. Osmanthus has been known in China since ancient times with the earliest writings coming from the Warring States period; the book ''Sea and Mountain. South Mountain'' states: "Zhaoyao Mountain had a lot of Osmanthus". Description ''Osmanthus'' range in size from shrubs to medium-sized trees, tall. The leaves are opposite, evergreen, and simple, with an entire, serrated or coarsely toothed margin. The flowers are produced in spring, summer or autumn, each flower being about 1 cm long, white, with a four-lobed tubular-based corolla ('petals'). The flowers grow in small panicles, and in several species have a strong fragrance. The fruit is a small (10–15 mm), hard-skinned dark blue to purple drupe containin ...

Paraphyletic
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor exc ... [...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 associated. 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 ...
