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. 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. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members

Asterales ( ASS-tər-RAY-leez) is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the

Asparagales (asparagoid lilies) are a diverse order of flowering plants in the monocots. Under the APG IV system of flowering plant classification, Asparagales are the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species, with members as varied as asparaguses, orchids, yuccas, irises, onions, garlics, leeks, and other alliums, daffodils, snowdrops, amaryllis, agaves, butcher's broom, agapanthuses, Solomon's seal, hyacinths, bluebells, spider plants, grasstrees, aloes, freesias, gladioli and crocuses. Most species of Asparagales are herbaceous perennials, although

The Cornales are an order of flowering plants, early diverging among the asterids, containing about 600 species. Plants within the Cornales usually have four-parted flowers, drupaceous fruits, and inferior to half-inferior gynoecia topped with disc-shaped nectaries.

The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 27 genera and ca. 900 known species of herbs, shrubs and trees. Over half of the species are in one genus, Polygala, the milkworts. The family was first described in 1809 by Johann Hoffmansegg and Johann Link. In 1896, Robert Chodat split it into three tribes. A fourth tribe was split off from the tribe Polygaleae in 1992. Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently,

Cytisus scoparius (syn. Sarothamnus scoparius), the common broom or Scotch broom, is a deciduous leguminous shrub native to western and central Europe. In Great Britain and Ireland, the standard name is broom; this name is also used for other members of the Genisteae tribe, such as French broom or Spanish broom; and the term common broom is sometimes used for clarification. In other English-speaking countries, the most common name is "Scotch broom" (or Scots broom); however, it is known as English broom in Australia. Though this plant is native to Europe, it has spread to many other parts of

The Tamaricaceae, the tamarisk family, are a family of plants native to drier areas of Europe, Asia, and Africa. It contains four genera: Tamarix (with 73 species), Reaumuria (25 species), Myricaria (13 species), and Myrtama (a single species). In the 1980s, the family was classified in the Violales under the Cronquist system; more modern classifications (Angiosperm Phylogeny Group) place them in the Caryophyllales. Many of the plants in the family grow on saline soils, tolerating up to 15,000 ppm soluble salt and can also tolerate alkaline conditions. The leaves are generally scale-like,

The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200 to 1350 species are in about 100 genera. All but seven of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another.

The Zygophyllales are an order of dicotyledonous plants, comprising the following two families: Family Zygophyllaceae Family Krameriaceae According to the Angiosperm Phylogeny Group (APG II) both families are unplaced to order, but nevertheless included in the Eurosids I. The APG III system of 2009, however, recognized this order. Even if the monogeneric family Krameriaceae shares few common traits with the family Zygophyllaceae, researchers see little advantage in keeping it as a separate family (e.g. Sheahan and Chase). The name Zygophyllales can be used if one finds it appropriate to place

Acacia dealbata, commonly known as silver wattle, blue wattle or mimosa, is a species of flowering plant in the legume family, Fabaceae. It is endemic to south-eastern mainland Australia but it can be found as an introduced or invasive species elsewhere. It is a bushy shrub or spreading tree with smooth bark, bluish grey or silvery and glaucous bipinnate leaves, spherical heads of yellow to bright yellow flowers, and straight to slightly curved pods. The Wiradjuri people of New South Wales use the name giigandul for the species.

Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the family Spirogyraceae, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater habitats. Spirogyra measures approximately 10 to 150 micrometres in width (though not usually more than 60) and may grow to several centimetres in length.

The order Polypodiales encompasses the major lineages of polypod ferns, which account for more than 80% of today's fern species. They are found in many parts of the world including tropical, semitropical and temperate areas.

The order Salviniales (formerly known as the Hydropteridales and including the former Marsileales) is an order of ferns in the class Polypodiopsida.

Senna occidentalis, commonly known as coffee senna, styptic weed, or septicweed, is a species of flowering plant in the family Fabaceae and is native to the southern United States of America, Mexico and South America. It is a shrub with pinnate leaves, with three to seven pairs of broadly elliptic to egg-shaped leaflets, and yellow flowers arranged in groups of two to four, with six fertile stamens in each flower. It is an aggressive, pantropical weed.

Philydraceae is a family of flowering plants composed of three genera and a total of six known species. The 2016 APG IV system places the family in the monocot order Commelinales. It consists of perennial, tropical plants in Southeast Asia and Australia.

Drosophyllum ( DROSS-oh-FIL-əm, rarely drə-SOF-il-əm) is a genus of carnivorous plants containing the single species Drosophyllum lusitanicum, commonly known as Portuguese sundew or dewy pine. In appearance, it is similar to the related genus Drosera (the sundews), and to the much more distantly related Byblis (the rainbow plants).

Melocactus (melon cactus), also known as the Turk's head cactus, Turk's cap cactus, or Pope's head cactus, is a genus of cactus with about 30–40 species. They are native to the Caribbean, western Mexico through Central America to northern South America, with some species along the Andes down to southern Peru, and a concentration of species in northeastern Brazil. The first species was named by Carl Linnaeus in 1753, as Cactus melocactus. When the genus was separated from Cactus, the pre-Linnaean name Melocactus was used. Acting on the principle of priority, in 1922 Nathaniel Britton and

Echinocactus is a genus of cacti in the subfamily Cactoideae. The generic name derives from the Ancient Greek ἐχῖνος (echînos), meaning "spiny," and cactus. It and Ferocactus are the two genera of barrel cactus. Members of the genus usually have heavy spination and relatively small flowers. The fruits are copiously woolly, and this is one major distinction between Echinocactus and Ferocactus. Propagation is by seed.

Panicoideae is the second-largest subfamily of the grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize (or corn), millet, sorghum, and switchgrass. C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 ancestor.

Nicotiana alata is a species of tobacco. It is called jasmine tobacco, sweet tobacco, winged tobacco, tanbaku, and Persian tobacco. Nictoiana alata is mainly grown as an ornamental plant; numerous cultivars and hybrids are derived from it. In Iran, narghila tobacco is sometimes produced from N. alata; it is not chopped like cigarette tobacco, but broken up by hand.

Gleicheniales is an order of ferns in the subclass Polypodiidae (the leptosporangiate ferns). The Gleicheniales has spore records potentially as early as the Early Carboniferous, but the oldest unambiguous macrofossil records date to the Early Permian.

Echinochloa colona, commonly known as jungle rice, wild rice, deccan grass, jharua or awnless barnyard grass, is a type of wild grass originating from tropical Asia. It was formerly classified as a species of Panicum. It is the wild ancestor of the cultivated cereal crop Echinochloa frumentacea, sawa millet. Some taxonomists treat the two taxa as one species, in which case the domesticated forms may also be referred to as E. colona.

Ophioglossaceae, from Ancient Greek ὄφις (óphis), meaning "snake", and γλῶσσα (glôssa), meaning "tongue", also known as the adder's-tongue family, is a small family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only family in the order Ophioglossales, which together with the Psilotales is placed in the subclass Ophioglossidae. The Ophioglossidae are one of the groups traditionally known as eusporangiate ferns. Members of the family differ from other ferns in a number of ways. Many have only a single fleshy leaf at a time. Their gametophytes are

Calicotome spinosa, the thorny broom or spiny broom, is a very spiny, densely branched shrub of the family Fabaceae which can reach up to three metres in height. It grows in the Western Mediterranean region on sunny slopes and dry, rocky ground. It is found in Spain, France, Italy, Croatia, Morocco, Tunisia, Libya, Algeria and Turkey, and it has been introduced to New Zealand. From March to June it produces bright yellow flowers which are borne singly or in small clusters. The seed-pods are 30mm long and are almost hairless, unlike those of the similar species Calicotome villosa.

Petrorhagia saxifraga, known as tunic flower or coat flower, is a small, herbaceous flowering plant in the family Caryophyllaceae. It is native to central and southern Europe, Turkey, the Caucasus, and Iran, and introduced to the United States and Canada, Great Britain, the Baltic States, Poland, and Sweden. Petrorhagia saxifraga is also known as tunic saxifrage, pink saxifrage, or just pink. It is a wiry plant with numerous branching stems, narrow leaves, and flowers growing solitary at the ends of branches. The petals range from pink to white. It is commonly cultivated in rock gardens and

Pachyphytum is a small genus of succulents in the stonecrop family, Crassulaceae, native to Mexico, where species can be found growing at elevations from 600 to 1,500 metres (2,000 to 4,900 ft) above sea level. The generic name comes from the ancient Greek pachys ('thick') and phyton ('plant'), a reference of the succulent nature of the leaves.

Echinochloa frumentacea (Indian barnyard millet, sawa millet, or billion dollar grass) is a species of Echinochloa. Both Echinochloa frumentacea and E. esculenta are called Japanese millet. This millet is widely grown as a cereal in India, Pakistan, and Nepal. Its wild ancestor is the tropical grass Echinochloa colona, but the exact date or region of domestication is uncertain. It is cultivated on marginal lands where rice and other crops will not grow well. The grains are cooked in water, like rice, or boiled with milk and sugar. Sometimes it is fermented to make beer. While also being part

Torilis arvensis is a species of flowering plant in the family Apiaceae known by the common names spreading hedge parsley, tall sock-destroyer and common hedge parsley. It is native to parts of Europe and it is known elsewhere, such as North America, as an introduced species and a common weed. It grows in many types of habitat, especially disturbed areas. It is an annual herb producing a slender, branching, rough-haired stem up to a meter in maximum height. The alternately arranged leaves are each divided into several pairs of lance-shaped leaflets up to 6 centimeters long each. The leaflet

Petrorhagia is a small genus of annual and perennial plants of the family Caryophyllaceae, mostly native to the Mediterranean region. It is low-growing with wiry stems and narrow, grass-like leaves. The flowers are small, in clusters similar to members of the genus Dianthus, in pink, lilac, or white. Petrorhagia saxifraga is the tunic flower or coat flower, similar to baby's breath, but shorter, and used in rock gardens. These plants are mainly native to Eurasia, but some species can be found nearly worldwide, having been introduced to other continents.

Ophrys speculum, the mirror orchid, is a species of Ophrys distributed throughout the Mediterranean that is pollinated exclusively by a single species of scoliid wasp.
