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.
Coleus Coleus is a former genus of flowering plants in the family Lamiaceae. In recent classifications, the genus is no longer recognized, and the formerly included species are instead placed in the genera "Plectranthus" and "Solenostemon". Because the type species, Coleus amboinicus ("Plectranthus amboinicus") is now placed in "Plectranthus", "Coleus" is regarded as a synonym of "Plectranthus". The term "coleus" is often used as a common name for species formerly placed in the genus "Coleus" that are cultivated as ornamental plants, particularly Coleus blumei ("Plectranthus scutellarioides"), which is popular as a garden plant for its brightly colored foliage.
