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.
Saururus Saururus is a genus of plants in the family Saururaceae containing two species. "Saururus cernuus" is native to North America, and "Saururus chinensis" is native to Asia.
