The Zanzibar examples of this common South-Asian plant (now widely spread in 

 warm- countries) were probably introduced into Afruja ; it may be otherwise with the 

 Tanga example.

This is separated generically from Justicia by Lindau on the ground that the 

 upper anther-cell is sometimes shortly tailed, as is the case in several other species of 

 Justicia (as in J. ximplicispica).
