Tax. note. — The habit of this species is quite similar to that of L. adenophyllum. The pu- 

 bescence of the stems is not properly described as "villous" but is of the same character as that in 

 L. adenophyllum, though slightly more obvious, that is to say it is spreading-hirsute, mostly 

 rather thin and chiefly or often wholly near the forks. The leaves are broader than in L. adeno- 

 phyllum and not, perhaps, as distinctly subcordate ; they are minutely white-dotted beneath as in 

 L. adenophyllum.
