Shimul (Semal):
Bengali derivative of the
flower/tree called Semal, often also called the silk-cotton tree. The petals of the Semal
flower are usually bright crimson or blood
red, have a very soft and smooth texture, and have cotton inside their pods.
Semal/Shimul
trees are often associated with the supernatural; according to folklore, these trees are some of the best places to find spirits, duppies and other supernatural entities. It is a symbol for great dichotomy, yet ultimately used for healing.
This is ultimately a rarely used word/term, most people simply using the word Semal instead.
