Are Libocedrus and Helianthus both types of plants?
Helianthus 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.
Lauraceae Lauraceae are the laurel family, that includes the true laurel and its closest relatives. This family of flowering plants comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as "Sassafras", are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. "Cassytha" is a genus unique to the Lauraceae family in that it is a genus of parasitic vines.
