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.
Helianthus exilis Helianthus exilis is a species of sunflower known by the common name serpentine sunflower. It is endemic to northern California (from Siskiyou County south to Napa County and Nevada County), where it grows mainly in mountainous areas, often in serpentine soils.
