Question: Between Pinanga and Alopecurus which genus is more common in temperate regions?

Passages:
Temperate forests correspond to forest concentration formed in the northern and southern hemisphere, or in temperate regions.  It is the same as a tropical forest except for the climate and some of the animals adaptations.  Main characteristics include: wide leaves, large and tall trees, large wild canopy and non seasonal vegetation.  Temperate forests can be further distinguished by weather patterns and geographical features that favor the predominance of certain kinds of trees.  In temperate coniferous forests, evergreen conifers predominate, while in temperate broadleaf and mixed forests, a more even distribution exists between evergreen trees and deciduous trees.  Temperate deciduous forests, a subgroup of temperate broadleaf forests, consist of trees that lose their leaves every year.  Finally, temperate rainforests typically have heavy rainfall and dense humidity.  But in some temperate forests there are just trees with needles and do not shed their leaves during the winter, so the climate is a little different and not as cold.  They are also known as montane forests. Lobelia ( ) is a genus of flowering plants comprising 415 species, with a subcosmopolitan distribution primarily in tropical to warm temperate regions of the world, a few species extending into cooler temperate regions.  They are known generally as lobelias. Helianthus or sunflower (from the Greek: ήλιος , "Hēlios", "sun" and ανθός , "anthos", "flower") L. is a genus of plants comprising about 70 species in the family Asteraceae.  The genus is one of many in the Asteraceae that are known as sunflowers.  Except for three species in South America, all "Helianthus" species are native to North America.  The common name, "sunflower", typically refers to the popular annual species "Helianthus annuus", or the common sunflower, whose round flower heads in combination with the ligules look like the sun.  This and other species, notably Jerusalem artichoke ("H. tuberosus"), are cultivated in temperate regions and some tropical regions as food crops for humans, cattle, poultry and ornamental plants.  The largest sunflower field is located in Tuscany, Italy. Lemna trisulca L. (syn.  "Staurogeton trisulcus" (L.) Schur; star duckweed; ivy-leaved duckweed) is a species of aquatic plants in the genus "Lemna" (duckweed) with a subcosmopolitan distribution, occurring in quiet freshwater habitats in cool temperate regions.  "L. trisulca" normally doesn't occur in warm temperate regions.  Unlike other duckweeds, it has submersed rather than floating fronds, except when flowering or fruiting. 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. Alopecurus, or foxtail grass, is a common and widespread genus of plants in the grass family.  It is common across temperate and subtropical parts of Eurasia, northern Africa, and the Americas, as well as naturalized in Australia and on various islands. Pinanga is a genus of flowering plant in the Arecaceae family, native to New Guinea and to eastern and southern Asia (India, China, Indonesia, Philippines, Indonesia, etc.). Alopecurus aequalis is a common species of grass known as shortawn foxtail or orange foxtail.  It is native to much of the temperate Northern Hemisphere from Eurasia to North America, where it can be found in many types of habitat. Temperate coniferous forest is a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest.  In most temperate coniferous forests, evergreen conifers predominate, while some are a mix of conifers and broadleaf evergreen trees and/or broadleaf deciduous trees. Temperate evergreen forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or mountain areas.  Temperate coniferous forests are only found in the Northern Hemisphere in North America, Europe, and Asia.  A separate ecoregion, the tropical coniferous forests, occurs in more tropical climates. 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.
