Are Libocedrus and Helianthus both types of plants?
Libocedrus Libocedrus is a genus of five species of coniferous trees in the cypress family Cupressaceae, native to New Zealand and New Caledonia. The genus is closely related to the South American genera "Pilgerodendron" and "Austrocedrus", and the New Guinean genus "Papuacedrus", both of which are included within "Libocedrus" by some botanists. These genera are rather similar to the Northern Hemisphere genera "Calocedrus" and "Thuja": in earlier days, what is now "Calocedrus" was sometimes included in "Libocedrus". They are much less closely related, as recently confirmed (Gadek et al. 2000). The generic name means "teardrop cedar", apparently referring to drops of resin.
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.
