Question: On which continent are both Halimium and Parkinsonia native?
Context: Parkinsonia , also Cercidium , is a genus of flowering plants in the pea family, Fabaceae.  It contains about 12 species that are native to semi-desert regions of Africa and the Americas.  The name of the genus honors English apothecary and botanist John Parkinson (1567–1650). The Military history of North America can be viewed as having four distinct phases.  The first is the precolonial period, during which warfare and conquest occurred from time to time between Native American tribes and alliances.  The second is the colonial period following the European discovery of the continent, during which the region saw both European efforts to wrest territories from their native inhabitante, and where European nations used their North American colonial possessions to wage wars with one another for the control of resources.  This phase culminated in the American Revolution, with the continent thereafter shifting away from European military domination.  The third phase was one of internal discord on the continent, including skirmishes between the United States and Canada, the Mexican–American War, the American Civil War and similar internal violence in Mexico, the Indian Wars, and the expulsion of the last major colonial bastion in the Spanish–American War. Parkinsonia florida, the blue palo verde (syn.  "Cercidium floridum"), is a species of palo verde native to the Sonoran Deserts in the Southwestern United States and Northwestern Mexico.  Its name means "green pole or stick" in Spanish, referring to the green trunk and branches, that perform photosynthesis. Women have made significant contributions to Latin music, a genre which predates Italian explorer Christopher Columbus' arrival in Latin America in 1492 and the Spanish colonization of the Americas.  The earliest musicians were Native Americans, hundreds of ethnic groups across the continent, whose lyrics "reflect conflict, beauty, pain, and loss that mark all human experience."  Indigenous communities reserved music for women, who were given equal opportunities with men to teach, perform, sing, and dance.  Ethnomusicologists have measured ceramic, animal-bone, and cane flutes from the Inca Empire which indicate a preference for women with a high vocal range.  Women had equal social status, were trained, and received the same opportunities in music as men in indigenous communities until the arrival of Columbus in the late 15th century.  European settlers brought patriarchal, machismo ideologies to the continent, replacing the idea of equality between men and women.  They equated native music with "savagery" and European music with "civilization".  Female musicians tended to be darker-skinned as a result of the slave trade (which increased the population of African slaves), and contemporary society denigrated music as a profession.  Latin music became Africanized, with syncopated rhythms and call-and-response; European settlement introduced harmony and the Spanish décima song form. Halimium halimifolium is a species of flowering plant in the family Cistaceae, native to Mediterranean Basin. Halimium ocymoides, the basil-leaved rock rose, syn.  "Cistus algarvensis" is a species of flowering plant in the family Cistaceae, native to southern Portugal and southern Spain.  It is an erect evergreen shrub growing to 60 cm tall by 100 cm wide, with woolly grey-green leaves and bright yellow flowers in spring.  The flowers may have a dark brown blotch at the base of each petal. Halimium lasianthum, the Lisbon false sun-rose or woolly rock rose, is a species of flowering plant in the family Cistaceae, native to southern Portugal and southern Spain.  It is a spreading evergreen shrub growing to 1 m tall by 1.5 m wide, with grey-green leaves and bright yellow flowers in spring.  The flowers may have a maroon blotch at the base of each petal. African art describes the modern and historical paintings, sculptures, installations, and other visual culture from native or indigenous Africans and the African continent.  The definition may also include the art of the native African, African diasporas, such as African American, Caribbean and other American art.  Despite this diversity, there are some unifying artistic themes when considering the totality of the visual culture from the continent of Africa. Halimium (rockrose, false sun-rose, or halimium) is a genus of 12 species of evergreen or semi-evergreen subshrubs in the family Cistaceae, closely related to "Cistus".  They are native to Europe, North Africa and Asia Minor, with the centre of diversity in the western Mediterranean region. The fauna of Australia consists of a huge variety of animals; some 83% of mammals, 89% of reptiles, 24% of fish and insects and 93% of amphibians that inhabit the continent are endemic to Australia.  This high level of endemism can be attributed to the continent's long geographic isolation, tectonic stability, and the effects of an unusual pattern of climate change on the soil and flora over geological time.  A unique feature of Australia's fauna is the relative scarcity of native placental mammals.  Consequently, the marsupials — a group of mammals that raise their young in a pouch, including the macropods, possums and dasyuromorphs — occupy many of the ecological niches placental animals occupy elsewhere in the world.  Australia is home to two of the five known extant species of monotremes and has numerous venomous species, which include the platypus, spiders, scorpions, octopus, jellyfish, molluscs, stonefish, and stingrays. Uniquely, Australia has more venomous than non-venomous species of snakes.
