t All works consulted, following Bentham, •£)]?ice Anisomeles mu^qv the *' Lamieee" 

 with the characteristic '" lower pair of stamens longest " without remark. In 1S93 

 I noted in Bengal specimens that the posterior pair are the longer and I have 

 repeatedly confirmed this observation in other districts.
