Initially documented in 2013 from the coastal regions of Kerala in India, the species is native to the New World. Its occurrence in West Bengal highlights the expanding range of this species within the Indian subcontinent. The paper provides a comprehensive description of the plant's morphological characteristics along with a map and field photographs to facilitate identification.
