This plant is extensively cultivated both in India and China, 
and yields the blue dye known in India as Room or Assam Indigo, 
and fully described by Fortune, in the place cited, as one of the 
Indigo Plants of China. 
On the authority of the late Dr. Hance (‘China Review,’ Jau.- 
Feb. 1881) another Acanthaceous plant is cultivated around 
Canton for its blue dye. It is named Lam Yip or Blue Leat ; 
and Hance states that it is quite different from Strobilanthes 
flaceidifolius, Nees, but in the absence of flowers he was unable 
to determine the genus.
