Datura metel
The name "Hua Lamphong" is the name of both a canal and a road (now Rama IV Road) that used to pass near this station. The name "Hua Lamphong", some say originated from the green plains surrounding the area in the past that were used to graze the cattle of the Muslim community, when the people saw the cattle running vigorously in the plains, it was named the "Thung Wua Lamphong" ('swaggering bulls plains'), eventually being called "Hua Lamphong". Others presumed that the name originated from a species of plant called "Lamphong" ("Datura metel"), a toxic plant that used to grow abundantly in the area.
