Question: Which of these are found only on a single continent, Pamianthe or Bombax?

Context paragraphs:
Pamianthe: Pamianthe is a genus of South American bulbous perennials in the Amaryllis family, subfamily Amaryllidoideae.  They can be found in sandy, but rocky areas in Ecuador, Peru, and Bolivia.

Ceraceosorales: The Ceraceosorales are an order of smut fungi in the class Exobasidiomycetes.  It is a monotypic order, consisting of a single family, the Ceraceosoraceae, which in turn contain a single monotypic genus, Ceraceosorus.  C. bombacis is a fungus that infects the tree "Bombax ceiba" in India.  This economically important tree is used as an ornamental tree.  Ceraceosorales was circumscribed in 2006; the family Ceraceosoraceae was validated in 2009.  "C. bombacis" was originally described as "Dicellomyces bombacis" in 1973, but B.K. Bakshi transferred it to the newly described "Ceraceosorus" three years later.

Quentovic: Quentovic was a Frankish emporium in the Early Middle Ages that was located on the European continent close to the English Channel.  The town no longer exists, but until recently it was thought to have been situated near the mouth of the Canche River in what is today the French commune of Étaples.  Archaeological discoveries led by David Hill in the 1980s found that the actual location of Quentovic was east of Étaples, in what is now the commune of La Calotterie.  It was an important trading place for the Franks and its port linked the continent to England, specifically to the southeastern county of Kent.  From what we know today, Quentovic was founded by a Neustrian king in the early 6th century.  It was one of the two most prominent Frankish ports in the north (the other being Dorestad) until it was abandoned, probably in the 11th century.  Merchants were drawn to this place because the number of trading posts at the time was limited.  Quentovic was also the place where Anglo-Saxon monks would cross the English Channel on their pilgrimage to Rome.  A lack of physical evidence, and the sudden disappearance of this emporium, make the town difficult to interpret.  Some of the most important historical evidence on Quentovic comes from documents of taxation and especially through the town’s minting of coinage.  Coins minted during both the Merovingian and the Carolingian dynasties have been found.

Jameson's red rock hare: Jameson's red rock hare ("Pronolagus randensis") is a leporid found only on the continent of Africa, mostly in the southern portion of the continent.  South Africa has a population of this red rock hare but it is only found in the northwestern part of the country.  Botswana also has a population in the Tswapong Hills.  Zimbabwe and Namibia are thought to have the largest populations of the red rock hare and it is said to be found throughout both countries.

BC (video game): B.C. was an action-adventure video game in development by Intrepid Computer Entertainment, a satellite of Lionhead Studios, which was to be published by Microsoft Game Studios for the Xbox.  It was cancelled in 2004 for unknown reasons.  "B.C." was going to take place during a prehistoric time period on a single continent which contained five levels.  The player controls a tribe who has to evolve and migrate to become the best species in the game.  Tribe members can be of different classes and each can level up different ways to evolve.  The main enemies in the game are an ape-like creature called the "simians"; however, the world is also inhabited with many types of dinosaurs as well as other creatures, including the dodo.  In 2015, game preservation group PtoPOnline revealed gameplay footage of B.C. from throughout the game's development.

South Polar dinosaur: The South Polar dinosaurs proliferated during the Early Cretaceous (145–100 Ma) while the continent of Australia was still linked to Antarctica to form East Gondwana, a continent that had rifted from Africa and drifted southward.  Much of this southern continent lay inside the Antarctic Circle, and the climate there was unlike any that exists today.  This led to fauna and flora that were unique to the time.  Much of what is known about the fauna of Polar Australia comes from fossil beds found in Dinosaur Cove and Flat Rocks on the Victorian coast of southeast Australia.

Climate of Africa: Due to Africa's position across equatorial and subtropical latitudes in both the northern and southern hemisphere, several different climate types can be found on the continent of Africa.  Africa mainly lies within the intertropical zone between the Tropic of Cancer and the Tropic of Capricorn.  Only the northernmost and the southernmost fringes of the continent have a Mediterranean climate.  Because of this geographical situation, Africa is a hot continent as the solar radiation intensity is always high.  Thus, warm and hot climates prevails all over Africa but the northern part is the most marked part by aridity and high temperatures.  The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-desert climate (semi-arid), the desert climate (hyper-arid and arid), the subtropical highland climate etc.  Temperate climates remain rare through the continent except at very high elevations and along the fringes.  In fact, the climate of Africa is more dependent to rainfall amount than to temperatures as they are consistently high.  African deserts are the sunniest and the driest parts of the continent due to the prevailing presence of the subtropical ridge with subsiding, hot, dry air masses.  Africa holds many heat-related records : the continent has the hottest extended region year-round, the areas with the hottest summer climate, the highest sunshine duration etc.

Geography of South America: The geography of South America contains many diverse regions and climates.  Geographically, South America is generally considered a continent forming the southern portion of the American landmass, south and east of the Panama–Colombia border by most authorities, or south and east of the Panama Canal by some.  South and North America are sometimes considered a single continent or supercontinent, while constituent regions are infrequently considered subcontinents.

Boundaries between the continents of Earth: The boundaries between the continents of Earth are generally a matter of geographical convention.  Several slightly different conventions are in use.  The number of continents is most commonly considered seven but may range as low as four when the Americas and Afro-Eurasia are each considered a single continent.  According to the definition of a continent in the strict sense, an island cannot be part of any continent, but by convention and in practice most major islands are associated with a continent.

Bombax: Bombax is a genus of mainly tropical trees in the mallow family.  They are native to western Africa, the Indian subcontinent, Southeast Asia, as well as subtropical regions of East Asia and northern Australia.  Distinguish from the genus Ceiba which has whiter flowers.
