Are Strelitzia and Smyrnium both types of plants?
yes
Smyrnium
Smyrnium is a genus of flowering plants in the family Apiaceae, the umbellifers.
Strelitzia
Strelitzia is a genus of five species of perennial plants, native to South Africa.
 It belongs to the plant family Strelitziaceae.
 The genus is named after the duchy of Mecklenburg-Strelitz, birthplace of Queen Charlotte of the United Kingdom.
 A common name of the genus is bird of paradise flower / plant, because of a resemblance of its flowers to birds-of-paradise.
 In South Africa it is commonly known as a crane flower and is featured on the reverse of the 50 cent coin.
 It is the floral emblem of the City of Los Angeles; two of the species, "Strelitzia nicolai" and "Strelitzia reginae", are frequently grown as house plants.
Heliconia
Heliconia, derived from the Greek word "helikonios", is a genus of flowering plants in the family Heliconiaceae.
 Most of the ca 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku.
 Many species of "Heliconia" are found in rainforests or tropical wet forests of these regions.
 Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia and Thailand.
 Common names for the genus include lobster-claws, toucan peak, wild plantains or false bird-of-paradise.
 The last term refers to their close similarity to the bird-of-paradise flowers ("Strelitzia").
 Collectively, these plants are also simply referred to as "heliconias". Pipeline Coastal Park
The Pipeline Coastal Park is an area of coastal vegetation in Amanzimtoti, Durban, South Africa.
 It is an elongated strip of land bordering the Indian Ocean.
 Plants found here include the "Mimusops caffra", "Strelitzia nicolai" and "Brachylaena discolor". Strelitzia nicolai
Strelitzia nicolai, commonly known as the giant white bird of paradise or wild banana, is a species of banana-like plants with erect woody stems reaching a height of 6 m and the clumps formed can spread as far as 3.5 m . Silene menziesii
Silene menziesii is a species of flowering plant in the pink family known by the common names Menzies' campion and Menzies' catchfly.
 It is native to western North America from Alaska through the western half of Canada to the southwestern United States.
 It can be found in many types of habitat and it is quite common in much of its range.
 It is variable in morphology and there are a number of varied subtaxa.
 In general, it is a perennial herb growing from a caudex, appearing matlike, decumbent, or erect, with stems a few centimeters to over half a meter long.
 It is usually hairy in texture, with upper parts bearing sticky glandular hairs.
 The leaves are lance-shaped, oppositely arranged in pairs, and a few centimeters in length, upper leaves usually smaller than lower.
 Flowers may occur in a cyme at the top of the stem, or in leaf axils, or both.
 Each is encapsulated in a hairy, veined calyx of fused sepals.
 The petals are white with two lobes at the tips.
 The plant is dioecious with male and female plants producing different flowers.
 The male and female flower types look the same externally; the stamens are reduced in female plants and the stigmas are reduced in the male. List of power stations in Nigeria
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. False vivipary
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. Ravenala
Ravenala is a genus of flowering plants with a single species, Ravenala madagascariensis, commonly known as traveller's tree or traveller's palm, from Madagascar.
 It is not a true palm (family Arecaceae) but a member of a monocotyledonous flowering plant family, Strelitziaceae.
 The genus is closely related to the southern African genus "Strelitzia" and the South American genus "Phenakospermum".
 Some older classifications include these genera in the banana family (Musaceae).
 Although it is usually considered to be a single species, four different forms have been distinguished. Trellis (architecture)
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.
