Gardenia
''Gardenia'' is a genus of flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, Asia, Madagascar and Pacific Islands, and Australia. The genus was named by Carl Linnaeus and John Ellis after Alexander Garden (1730–1791), a Scottish-born American naturalist. Description Gardenias are evergreen shrubs and small trees growing to tall. The leaves are opposite or in whorls of three or four, long and broad, dark green and glossy with a leathery texture. The flowers are solitary or in small clusters, white, or pale yellow, with a tubular-based corolla (botany) with 5–12 lobes (petals) from diameter. Flowering is from about mid-spring to mid-summer, and many species are strongly scented. Phytochemistry Many of the native gardenias of the Pacific Islands and elsewhere in the paleotropics possess a diverse array of natural products. Methoxylated and oxygenated flavonols, flavones, and triterpenes accumulate on the vegeta ...

Gardenia Jasminoides
''Gardenia jasminoides'', commonly known as gardenia, is an evergreen flowering plant in the coffee family Rubiaceae. It is native to parts of South-East Asia. Wild plants range from 30 centimetres to 3 metres (about 1 to 10 feet) in height. They have a rounded habit with very dense branches with opposite leaves that are lanceolate-oblong, leathery or gathered in groups on the same node and by a dark green, shiny and slightly waxy surface and prominent veins. With its shiny green leaves and heavily fragrant white summer flowers, it is widely used in gardens in warm temperate and subtropical climates. It also is used as a houseplant in temperate climates. It has been in cultivation in China for at least a thousand years, and it was introduced to English gardens in the mid-18th century. Many varieties have been bred for horticulture, with low-growing, and large, and long-flowering forms. Description ''Gardenia jasminoides'' is a shrub that ranges from 30 cm to 3 m (1–10&nb ...

Gardenia Actinocarpa
''Gardenia actinocarpa'' is a rare and endangered plant in the madder family Rubiaceae that grows in a very restricted area within the Wet Tropics rainforest of north-east Queensland. Description This species grows as an evergreen understory plant, reaching up to in height but flowering and fruiting once it reaches around . It is a spindly arborescent shrub with a stem diameter of around at breast height. The leaves are opposite and chartaceous (papery) with wavy edges, glossy mid green above and paler below, and attached to the twigs with a petiole around long. They measure between long and wide, and are generally obovate in shape. They have a long attenuate (tapering) base and an extended "drip tip". Stipules are conical, up to long and resinous. Flowers are terminal, solitary, actinomorphic and 6-merous, borne on pedicels between long. The calyx tube is green, coriaceous, and has six external longitudinal ridges extending into the laterally compressed calyx l ...

Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', ''Ixora'', ''Pentas''), and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar stipules, tubu ...

Gardenia Anapetes
''Gardenia anapetes'' is a species of plant in the family Rubiaceae. It is endemic to the Fiji island of Vanua Levu Vanua Levu (pronounced ), formerly known as Sandalwood Island, is the second largest island of Fiji. Located to the north of the larger Viti Levu, the island has an area of and a population of 135,961 . Geology Fiji lies in a tectonically .... The native gardenias of Fiji possess a diverse array of natural products. Methoxylated and oxygenated flavonols and triterpenes accumulate on the vegetative- and floral-buds as droplets of secreted resin. Phytochemical studies of these bud exudates have been published, including a population-level study of two other rare, sympatric species on Vanua Levu Island, ''G. candida'' and ''G. grievei''.Miller, J. M. and S. Sotheeswaran. 1993. Bud exudate composition and ecogeography of Fijian Gardenia species (Rubiaceae).

Alexander Garden (naturalist)
Alexander Garden FRSE FRS (January 1730 – 15 April 1791) was a Scottish physician, botanist and zoologist. The gardenia flower is named after him. He lived for many years in Charleston, South Carolina, using his spare time to study plants and living creatures, and sending specimens to Carl Linnaeus. Biography Garden was born in January 1730 in Birse, Aberdeenshire, the son of Rev Alexander Garden (1685–1756) the parish minister. He studied medicine at Marischal College in the mid-1740s, discovering an interest in natural history while there. After two years as a surgeon's assistant in the navy, he continued his medical studies at the University of Edinburgh. One of his teachers was Charles Alston, the King's Botanist and Keeper of the Garden at Holyrood where medicinal plants were cultivated; Alston was an influence on Garden's growing interest in botany.''DNB'' An opportunity came to practise medicine in South Carolina, where, a distant relative Reverend Alexander Gar ...

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic 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. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Systematics
Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branches to further understand the relationshi ...
