Magnoliids (or Magnoliidae or Magnolianae) are a group of flowering plants. Until recently, the group included about 9,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others. That group is characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves. More recently, "Magnoliidae", but not "magnoliids" is used for the entire group of flowering plants, and the formal name for the smaller group is "Magnolianae".
