Genera 10, apeniea 230, mostly seaside or salt marsh plants, found In nil latitudes. 



Properties.— tius root of Stalice Limonium is one o( the best and most powerful of all astrin- 

 irents. The species of Plumbago are acrid and escharotic, so much so, that the roots of P. Eu- 

 roptens are said by Lindley to be employod in Eoropo by beggars, to raise blisters on the Oaee, 

 in order to excite compassion.
