390 LXXXVI. LENTIBULACE.E. PINGUICULA. 



Properties.-- The root of Statice Limonium is one of the best and most powerful of all astringents. 

 The species of Plumbagp are acrid and escharotic, so much so, that the roots of P. Europasus are said by 

 Lindley to be employed in Europe by beggars, to raise blisters on the face, in order to excite compassion.
