P. majus L. preserves all its characters in Maderse; and the present 

 plant appears a genuine species, though in some sort intermediate be- 

 tween P. majus and inmu.s ; having the mucronatc calyxes of the former, 

 and hairiness of the latter. In the siiaj)e of the leaves it seems to differ 

 from both.
