Input: [header] How to identify trees by leaves [title] Determine the leaf type. [step] The most common leaf type is a broadleaf, which is wide and flat. But leaves also come in needle, cactus, and scale types. <sep> (A) Some species are 226 markups with narrow leaves, while others have branches that narrow to a single leaf near a central branch. Some other species may have leaf fronds that are much smaller. (B) Needle leaves are long and pointed like a pin, cactus leaves are thick and usually covered in spines, and scales leaves are thin, oblong leaves that primarily belong to cypress trees. Compare your leaf to the different basic leaf types to narrow down what species your leaf might be. (C) Cottonwood-hickory branches dry up and flowers flower on your plant can be expanded: they or roots appear to be green, brown or maroon, depending on the plant the tree is indigenous to. Tenessap is from this umbrella system. (D) You'll want a thicker leaf for a well-made tree, while an thinner leaf for a woody tree. Though these differences will have to be avoided, they can be factored into your pricing process.
Output:
B
