Gasteranthus is a genus of 35 species of herbs and soft-stemmed subshrubs in the flowering plant family Gesneriaceae. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its Asteridae is a Botanical name at the rank of subclass. Circumscription of the subclass has varied with the taxonomic system being In the APG II system (2003 for the classification of Flowering plants, the name asterids refers to a Clade (a Monophyletic group The order Lamiales is a Taxon in the asterid group of dicotyledonous Flowering plants. Gesneriaceae is a family of Flowering plants consisting of ca In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Gesneriaceae is a family of Flowering plants consisting of ca The species occur in Central America and South America, from southernmost Mexico to Bolivia[1]. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The United Mexican States ( or commonly Mexico (ˈmɛksɪkoʊ () is a federal constitutional Republic in North America. The Republic of Bolivia (República de Bolivia) named after Simón Bolívar, is a Landlocked country in central South America. Numerous species are threatened with extinction, mainly due to deforestation. In Biology and Ecology, extinction is the cessation of existence of a Species or group of taxa. Deforestation is the conversion of Forested areas to non-forest land for use such as Arable land, Pasture, urban use logged area or wasteland

These plants inhabit tropical forest and cloud forest. The Tropics are centered on the Equator and limited in Latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' (23 A forest is an area with a high density of Trees There are many definitions of a forest based on various criteria A cloud forest, also called a fog forest, is a generally Tropical or Subtropical evergreen Montane moist forest characterized by a They grow in humid, shaded locations at altitudes of up to 1,800 m ASL. Humidity is the amount of water vapor in the air In daily language the term "humidity" is normally taken to mean Relative humidity. The term above mean sea level ( AMSL) refers to the Elevation (on the ground or Altitude (in the Air) of any object relative to the The flowers are usually colored in orange hues and often spotted, but background colors also include shades white, yellow and red. They are born in axillary cymes without bracteoles. In Botany, a bract is a modified or specialized Leaf. Bracts are ordinarily associated with reproductive structures (subtending Flowers Inflorescence [1]

Gasteranthus was previously included in the closely related genus Besleria. Besleria is a Genus of ca 150 species of large Herbs and soft-stemmed Subshrubs or Shrubs in the Flowering plant family The two genera have been separated on the basis of differences in their stomata (aggregated in Gasteranthus, scattered in Besleria) and fruits (fleshy capsule in Gasteranthus, berry in Besleria). In Botany, a stoma (also stomate; plural stomata) is a tiny opening or pore found mostly on the underside of a Plant Leaf In Botany a capsule is a type of simple dry Fruit produced by many species of Flowering plants A capsule is a dehiscent structure composed of two The word berry has two meanings one based on a botanical definition the other on common identification Characteristic are the whitish dots on the leaf undersides caused by aggregations of stomata in Gasteranthus. [2]

Two main groups can be distinguished in this genus: one group of species, with white to yellow, bell- or tube-shaped flowers, is probably pollinated mainly by euglossine bees. Pollination in angiosperms and Gymnosperms is the process that transfers pollen grains, which contain the male Gametes (sperm to where the female Euglossine bees, also called orchid bees, are the only group of corbiculate bees whose non-parasitic members do not all possess eusocial behavior. The other group has bright orange or red hypocyrtoid (inflated corolla tube with very small opening) flowers and are apparently pollinated mainly by hummingbirds. A petal (from Ancient Greek petalon "leaf" "thin plate" regarded as a highly modified leaf is one member or part of the corolla Hummingbirds are Birds in the family Trochilidae, and are endemic to the Americas.
