Plantation teak is a tropical hardwood tree from the genus "Tectona", endemic to Southeast Asia that is exclusively planted for the purpose of forestry management, for either commercial or ecological purposes.
 Although the genus Tectona is native to the tropical regions of Southeast Asia, primarily Indonesia, Myanmar, Bangladesh and Thailand, the cultivation of plantation teak is economically viable in other tropical regions such as Central America.
Episcia is a genus of 10 species belonging to the flowering plant family Gesneriaceae.
 The species are found in the tropical regions of Central America and South America (frequently cultivated elsewhere and sometimes naturalizing in tropical regions).
 The species are perennial herbaceous plants characterized by a stoloniferous habit, red (rarely orange, pink, blue or yellow) flowers, and frequently have marked or patterned leaves.
 They are grown in the tropics, and in temperate regions as houseplants, primarily for their attractive foliage.
 Numerous cultivars have been produced, primarily by selection and hybridization of the species "E. cupreata" and "E. reptans".
Spathiphyllum is a genus of about 40 species of monocotyledonous flowering plants in the family Araceae, native to tropical regions of the Americas and southeastern Asia.
 Certain species of "Spathiphyllum" are commonly known as Spath or peace lilies.
The Muntingiaceae are a family of flowering plants, belonging to the rosid order Malvales.
 The family consists of three genera: "Dicraspidia", "Muntingia" and "Neotessmannia", each with a single species.
 They are woody plants of the tropical regions of America.
 The older Cronquist System placed these genera in the family Tiliaceae, with which they share morphological similarities but have no evolutionary affinity. "
Muntingia calabura" is widely introduced in tropical regions, because of its edible fruit.
 "Dicraspidia donnell-smithii" and "Neotessmannia uniflora" are the other two species in the family, the latter only known from herbarium specimens.
Xanthosoma is a genus of flowering plants in the arum family, Araceae.
 The genus is native to tropical America but widely cultivated and naturalized in other tropical regions.
 Several are grown for their starchy corms, an important food staple of tropical regions, known variously as "malanga", "otoy", "otoe", cocoyam (or new cocoyam), "tannia", "tannier", "yautía", "macabo", "ocumo", "macal", "taioba", "dasheen", "quequisque", "ʻ ape" and (in Papua New Guinea) as Singapore taro ("taro kongkong").
 Many other species (including especially "X. roseum") are used as ornamental plants, and in popular horticultural literature are known as ‘ape or elephant ear (from the purported resemblance of the leaf to an elephant's ear), although the latter name is sometimes also applied to members with similar appearance and uses in the closely related genera "Caladium", "Colocasia" (i.e., taro), and "Alocasia".
Macroptilium atropurpureum, commonly referred to as "purple bush-bean", or "siratro" is a perennial legume recognized by its climbing dense green vines and deep purple flowers.
 The plant is indigenous to the tropical and subtropical regions of North, Central and South America, as far north as Texas in the USA and as far south as Peru and Brazil, but it can be found in many tropical regions around the world.
 Rich in protein, "Macroptilium atropurpureum" is commonly used for cattle pastures intercropped with grass, used in hay, or as a ground cover to prevent soil erosion and to improve soil quality.
Phragmites is a genus of four species of large perennial grasses found in wetlands throughout temperate and tropical regions of the world.
 The World Checklist of Selected Plant Families, maintained by Kew Garden in London, accepts the following four species:
Cuscuta ( ) (dodder) is a genus of about 100–170 species of yellow, orange, or red (rarely green) parasitic plants. Formerly treated as the only genus in the family Cuscutaceae, it now is accepted as belonging in the morning glory family, Convolvulaceae, on the basis of the work of the Angiosperm Phylogeny Group.
 The genus is found throughout the temperate and tropical regions of the world, with the greatest species diversity in subtropical and tropical regions; the genus becomes rare in cool temperate climates, with only four species native to northern Europe.
Ornithonyssus bacoti is a hematophagous parasite commonly referred to as the tropical rat mite.
 They feed only on blood and serum from many hosts.
 They can be found and cause disease on rats and wild rodents most commonly, but also small mammals and humans when other hosts are scarce.
 Outbreaks tend to occur in older, less maintained buildings.
 The mite, however, can travel several hundred feet on its own if necessary to find a host and can survive for extended periods of time without a host.
 This, along with the nonspecific dermatitis it causes, can prevent accurate and fast diagnosis of rat mite dermatitis.
 The scarcity of reports, due in part to misdiagnosis and also the mildness of its symptoms, makes the disease seem less common than it is.
 The tropical rat mite can be found in both temperate and tropical regions or rather all continents except the arctic and Antarctic.
Picrasma is a genus of flowering plants in the family Simaroubaceae, comprising six to nine species native to temperate to tropical regions of Asia, and tropical regions of the Americas.
 The species are shrubs and trees growing up to 20 m tall.

Question: Can both Spathiphyllum and Phragmites be found in tropical regions of the world ?
Answer: yes
