Rarely, some cypress trees (of the Chamaecyparis genus) also have butterfly-shaped stomatal bands, in which case the egg-shaped hooked seed cones (see cones below) in clusters in the Thuja genus can usually differentiate the two. They can often be differentiated by the fact that Thuja typically has visible whitish bands of stomata on the lower side, usually in the shape of a butterfly, while cypress trees often have no visible bands, or they have ‘X’ or ‘Y’ shaped bands (see stomata below). When similar-looking, junipers can be distinguished by their berry-like seed cones (see cones below).Ĭypress trees are often confused with the related North American false cedars ( Thuja spp) that have very similar scale-like leaves in flattened shoots. Some junipers have awl-shaped leaves that are easier to distinguish from cypress, while others have scale-like leaves that tend to be four-ranked, look quite similar, or may appear more delicate and intricate-looking. The closely related juniper trees have variable leaves.
