There are many types of trees. Scientists divide them into two groups. One group is called hardwood. The other is softwood.Hardwood trees have broad leaves. Their leaves change color in the fall. They drop their leaves. They grow back in spring. Hardwood trees produce flowers and seeds.Softwood trees have needle-like leaves. They stay green all year. They do not drop their leaves. Softwoods do not flower. Their seeds are in cones.Recently, researchers studied 33 trees. One is a tulip tree. They found that it is not hardwood or softwood. The researchers studied the trees’ microfibrils. These tiny fibers store carbon. Plants take in carbon from the air. The researchers discovered that softwood microfibrils are larger than hardwood. The tulip tree's microfibrils are midway between the hardwood and softwood. It is a new type of wood. The researchers called it “midwoods”. The researchers plan to study midwood trees more.
