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.
Leymus multicaulis Leymus multicaulis, also known as manystem wild rye or manystem lyme grass, is a species of the "Leymus" genus. The species name of manystem wild rye, "multicaulis", suggests the “many stems” of the species. "Leymus multicaulis" is considered a type of grass. Manystem wild rye has only one cotyledon in each of its seeds. The xylem and phloem within the roots are arranged in a ring pattern. The vascular bundles are scattered throughout the stem. These traits make "Leymus multicaulis" a monocot. "Leymus multicaulis" is a flowering plant, or angiosperm.
