We are led to include so great a number of synonyms under 

 the above species from a careful examination of the descriptions 

 and figures, as well as of authentic specimens, whenever we could 

 have recourse to them. 



It is a plant which, growing in almost every variety of soil 



and situation, is subject to alter considerably in its appearance. 



The form of the leaf, however, we find to be tolerably constant. 



10. T. stellata; stems very short tufted, leaves oblongo-ovate or 



ovate rather concave subopaque mucronulate furnished with 



a strong brown nerve. (TAB. XII.)
