Question: Are Egeria and Kunzea both native to south of the equator?
Context: Sagina (like "Colobanthus" called "pearlworts") is a genus of 20–30 species of flowering plants in the pink or carnation family, Caryophyllaceae.  These are flowering herbs native to temperate regions of the Northern Hemisphere extending south to tropical mountain areas at high altitudes, reaching just south of the equator in Africa.  They are small annual or perennial herbaceous plants, growing to 5–15 cm.  The leaves are opposite, often in tight whorl-like clusters, simple linear, typically 5–20 mm long.  The flowers are solitary or in small cymes, with four or five green sepals and an equal number of white petals; the petal size relative to the sepal size is useful in species identification.  The fruit is a small capsule containing several seeds. Tephrosia elongata is a legume native to Africa south of the equator.  It occurs from northern and eastern South Africa to the highlands of Malawi and Tanzania. Egeria densa, the large-flowered waterweed or Brazilian waterweed, is a species of "Egeria" native to warm temperate South America in southeastern Brazil, Argentina, and Uruguay.  It is considered a problematic invasive species due to its use in home aquariums and subsequent release into non-native habitats. Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia.  They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves.  The flowers are similar to those of plants in the genus "Leptospermum" but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but are few occur in eastern Australia and a few are found in New Zealand.  The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids. Salvia hirtella is a herbaceous perennial shrub native to the Ecuador province of Cotopaxi, found both north and south of the equator.  Its native habitat is limited to high in the Andes mountains, with most plants collected around 12,000 ft elevation. Muehlenbeckia or the maidenhair genus is native to the Southern Hemisphere, especially South America, Papua New Guinea, Australia and New Zealand, and has been introduced both by birds and cultivation to temperate locales north of the equator.  Some are tiny alpine mat-forming plants whereas others are vigorous vines with masses of dark stems and minimal small bronze-tinged leaves.  In virtually frost-free environments, rampant species can become weedy and difficult to eradicate. The greater striped swallow ("Cecropis cucullata") is a large swallow that is native to Africa south of the equator. Egeria is a genus of three species of aquatic plants in the family Hydrocharitaceae described as a genus in 1849.  native to warm-temperate South America. Kunzea capitata is a shrub species in the family Myrtaceae.  It is native to New South Wales in Australia. This is a list of the native wild mammal species recorded in Mexico.  As of September 2014, there were 536 mammalian species or subspecies listed.  Based on IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors.  Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra.  The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison.  Mexico includes much of the Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic ecozone.  However, the lowlands of southern Mexico are linked with Central America and South America as part of the Neotropic ecozone.  Extensive mixing of Nearctic and Neotropical mammal species commenced only three million years ago, when the formation of the Isthmus of Panama ended South America's long period of isolation and precipitated the Great American Interchange.  Twenty of Mexico's extant nonflying species (opossums, armadillos, anteaters, monkeys and caviomorph rodents) are of South American origin.  Most of the megafauna that formerly inhabited the region became extinct at the end of the Pleistocene about 10,000 years ago, shortly after the arrival of the first humans.  Increasing alteration and destruction of natural habitats by expanding human populations during the last several centuries is causing further attrition of the region's biodiversity, as exemplified by the 'hotspot' designations (by definition, such areas have lost over 70% of their primary vegetation).
