          They should also have a good breed and mean prosperity, longevity, have dark green leaves, single leaves, purple or pinkish-purple flowers, and nicknamed "Queen's Flower" (Queen's Flower). Their pods should refuse to leave the trees. There should have many more species in one family and their flowers should have characteristics of Queen's crape myrtle, such as crape myrtle, crape myrtle, and the crape myrtle.


          The committee finally voted to select the name of this species "Inthanin" as an auspicious name and tree to the university. It means affiliations with the university. Inthanin has the characteristics of the inflorescences, tighten clusters, and bright colors like love and unity as one. It signifies its tightness between the university and its alumni throughout their careers everywhere.


          Inthanin or the trees in this family are economic woods. It has a medium-hard to hardwood used as an ornamental plant for shade with bright and beautiful flowers. Its bark and leaves can be used as herbal medicine like the value of Maejo alumni who have created benefits for the society and nation for a long period of more than 50 years.
