The genus is found throughout the tropical and warm temperate regions of the world, but does not extend into the more northerly temperate regions.
 Most species occur in the southern hemisphere, with a third of species occurring in Australia.
 This distribution pattern has been thought to indicate that the genus was once much larger, and has declined in the face of competition with more competitive wasp genera, leaving the genus largely concentrated in geographically-isolated regions.
Astragalus is a large genus of about 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae.
 It is the largest genus of plants in terms of described species.
 The genus is native to temperate regions of the Northern Hemisphere.
 Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ("A. gummifer", "A. tragacanthus").
 Some pale-flowered vetches are similar in appearance, but vetches are more vine-like.
The Ebenaceae are a family of flowering plants belonging to order Ericales.
 It includes ebony and persimmon among about 768 species of trees and shrubs.
 The family is distributed across the tropical and warmer temperate regions of the world.
 The family is most diverse in the rainforests of Malesia, India, tropical Africa and tropical America.
Cimicifuga (bugbane or cohosh) was a genus of between 12-18 species of flowering plants belonging to the family Ranunculaceae, native to temperate regions of the Northern Hemisphere.
Gnaphalium affine, also known as Jersey cudweed, is a species of plants belonging to the genus "Gnaphalium".
 The species grows extensively in East Asia including temperate regions of China, Korea, Japan, and Taiwan as well as some high altitude tropical regions of India, Nepal, and Thailand.
The Platanaceae are a family of flowering plants belonging to the order Proteales.
 This family has been recognized by almost all taxonomists, and is sometimes called the "plane-tree family".
 The family consists of only a single extant genus "Platanus", with eight known species.
 The plants are tall trees, native to temperate and subtropical regions of the Northern Hemisphere.
 The hybrid London plane is widely planted in cities worldwide.
Malva pusilla, also known as Malva rotundifolia (the latter of which is now officially rejected by botanists), the low mallow, small mallow, or the round-leaved mallow, is an annual and biennial herb species of the Mallow genus "Malva" in the family of Malvaceae.
 Malva is a genus that consists of about 30 species of plants.
 This genus consists of plants named mallows.
 Mallows grow in many regions, including temperate, subtropical, and tropical areas.
Cerastium is a genus of annual, winter annual, or perennial plants belonging to the family Caryophyllaceae.
 They are commonly called mouse-ear chickweed.
 Species are found nearly worldwide but the greatest concentration is in the northern temperate regions.
 There are about 200 species.
 A number are common weeds in fields and on disturbed ground.
Malva is a genus of about 25–30 species of herbaceous annual, biennial, and perennial plants in the family Malvaceae (of which it is the type genus), one of several closely related genera in the family to bear the common English name mallow.
 The genus is widespread throughout the temperate, subtropical and tropical regions of Africa, Asia and Europe.
 The word "mallow" is derived from Old English "malwe", which was imported from Latin "malva", cognate with Ancient Greek μαλάχη (malakhē) meaning "mallow", both perhaps reflecting a Mediterranean term.
 A number of species, previously considered to belong to "Lavatera", have been moved to "Malva".
The waterfowl genus Anser includes all grey geese (and sometimes the white geese).
 Its name is derived from "anser" the Latin for "goose".
 It belongs to the true geese and swan subfamily (Anserinae).
 The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer.
 Some also breed further south, reaching into warm temperate regions.
 They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) to 5 °C (41 °F) isotherms.

Question: Are plants belonging to the genus Astragalus and the genus Malva both native to temperate regions?
Answer: yes
