Question: What continent can both Thlaspi and Calophyllum be found?
Context: Thlaspi caerulescens, Alpine Penny-cress and also known as alpine pennygrass, is a flowering plant in the family Brassicaceae.  It is found in Scandinavia and Europe. Piptostigma calophyllum is a species of plant in the Annonaceae family.  It is found in Cameroon and Gabon.  Its natural habitat is subtropical or tropical moist lowland forests.  It is threatened by habitat loss. 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. Palaquium calophyllum is a tree in the Sapotaceae family.  It grows up to 20 m tall.  The bark is brownish grey.  Inflorescences bear up to 12 flowers.  The fruits are round, up to 2 cm in diameter.  The specific epithet "calophyllum " is from the Greek meaning "beautiful leaves".  Habitat is forests from sea-level to 800 m altitude.  "P. calophyllum" is found in Sumatra, Borneo, the Philippines, Maluku and New Guinea. Calophyllum neoebudicum is a species of tree in the Calophyllaceae family.  It is found in American Samoa, Fiji, Indonesia, Papua New Guinea, Samoa, the Solomon Islands, Tonga, and Vanuatu. Calophyllum is a genus of tropical flowering plants in the family Calophyllaceae.  They are mainly distributed in Asia, with some species in Africa, the Americas, Australasia, and the Pacific Islands. Calophyllum elegans is a species of tropical flowering plants in the family Calophyllaceae.  It is a 9.1 m (30 feet) tall tree found in Asia. Thlaspi, or pennycress, is a genus of herbs of temperate regions of the Eurasian continent.  They occur in Central and South Europe, South-West Asia and 2 species are endemic to China.  The "Thlaspi" has been proven to be a hyperaccumulator of heavy metals such as zinc and cadmium and therefore may be used in phytoremediation initiatives. Calanolide A is an experimental non-nucleoside reverse transcriptase inhibitor (NNRTI) first acquired from the "Calophyllum lanigerum," variety "austrocoriaceum," trees in the Malaysian state of Sarawak by botanist John Burley in 1987.  The U.S. National Cancer Institute tested calanolide A as a possible cancer treatment, but had no effect.  It was later found to have potent anti-HIV activity.  On return trip to Malaysia, it was found that all of the "austrocoriaceum" variety tree species of "Calophyllum lanigerum" had been cut down most likely for fuel and building material in the swamp forest near Lundu where the first tree samples were taken; however, a few existing species were eventually located in the Singapore Botanic Garden.  Since the plant source is relatively rare, a total synthesis was developed in 1996.  The form in current use is formulated for oral administration and produced by Sarawak MediChem in Lemont, Illinois. Calophyllum macrophyllum is a species of flowering plant in the Calophyllaceae family.  It is found only in Maluku, Indonesia.
