Rhododendron
Azalea is a branch of azalea. It is widely distributed from the temperate zone to the southernmost part of the north and south, but some are also in the tropical alpine. In Korea, there are 23 species of 7 genera including azalea, azaleas, sparrow trees, poisonous poisonous plants, and rhododendrons. Most are shrubs, but some species are small trees. Leaves have no stipules and are usually out of alignment. Flowers are bisexual and many are radial symmetry. Most of the petals are combined to form a funnel, a bell or just a corolla, but some are separated from each other. The number of surgeries is usually twice the number of petals that form the corolla, but sometimes it is the same number. Ovaries are either upper or lower, usually divided into 5 rooms, sometimes with 1 room. Fruits are mainly capsules and bowls.
