magnoliids
Magnoliids (or Magnoliidae) are a group of about 9,000 species of flowering plants, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others. They are characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves.
==Classification==
Traditionally, Magnoliidae is the botanical name of a subclass. The circumscription of a subclass will vary with the taxonomic system being used. The only requirement is that it must include the family Magnoliaceae.〔ICBN, Art. 16〕 More recently, the group has been redefined under the ''PhyloCode'' as a node-based clade comprising the Canellales, Laurales, Magnoliales, and Piperales.
