There are currently two main types of power plants operating in Nigeria: (1) hydro-electric and (2) thermal or fossil fuel power plants.
 With a total installed capacity of 8457.6MW (81 percent of total) in early 2014, thermal power plants (gas-fired plants) dominates the Nigerian power supply mix.
 Electricity production from hydroelectric sources (% of total) in Nigeria was reported at 17.59 % in 2014, according to the World Bank collection of development indicators, compiled from officially recognized sources.
 There have been two main types of fossil fuel/thermal power plants in the country: (i) coal-fired and (ii) natural gas-fired.
Boltonia caroliniana, common name Carolina doll’s-daisy, is a North American species of plants in the sunflower family.
 It is found only in the southeastern United States, primarily in the states of North Carolina, South Carolina, and Virginia with a few isolated populations in western Georgia.
Boltonia apalachicolensis, common name Apalachicola doll’s-daisy, is a North American species of plants in the sunflower family.
 It is found only in the "panhandle" region of northwestern Florida in the United States.
Distylium (winter-hazel) is a genus of about 18 species of evergreen shrubs and trees in the witch hazel family, Hamamelidaceae, native to eastern and southeastern Asia.
Boltonia montana (mountain doll's daisy), is a North American species of plants in the sunflower family.
 It is found only in the east-central part of the United States, in the states of New Jersey, Pennsylvania, and Virginia.
False vivipary is an abnormal condition found in many types of plants in which a plantlet is produced where the flower should appear.
 It is not a completely understood topic, but some say it could be caused by a hormonal mistake.
 The plantlet which appears can be rooted and grown like normal plants.
 This abnormal behavior can occasionally be seen in many types of carnivorous plants.
Boltonia lautureana is an East Asian species of plants in the sunflower family.
 It is native to China, Japan, Korea, and Asiatic Russia.
Boltonia is a genus of plants in the sunflower family native primarily to North America with one species in eastern Asia.
Boltonia diffusa (smallhead doll's daisy) is a North American species of plants in the sunflower family.
 It native to the United States, primarily the states along the Gulf of Mexico from Texas to Florida plus the lower Mississippi Valley from Louisiana to Illinois.
 There additional populations in the eastern United States as far north as Virginia.
A trellis (treillage) is an architectural structure, usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal that is normally made to support and display climbing plants, especially shrubs.
 There are many types of trellis for different places and for different plants, from agricultural types, especially in viticulture, which are covered at vine training systems, to garden uses for climbers such as grapevines, clematis, ivy, and climbing roses or other support based growing plants.
 The rose trellis is especially common in Europe and other rose-growing areas, and many climbing rose varieties require a trellis to reach their potential as garden plants.
 Some plants will climb and wrap themselves round a trellis without much artificial help being needed while others need training by passing the growing shoots through the trellis and/or tying them to the framework.
