     TOOTHWORT (Dentaria diphylla) 
     
    
   
   
    
     This plant was dicovered on May 
     
     24, 1983 and is believed to be the 
     
     first record of this plant in P.E.I. 
     
    

    
     It was found in boggy soil about 
     
     200 yards below Indian Bridge on the 
     
     Morell River, and about three or four 
     
     yards from the edge of the stream. There 
     
     were two colonies, one about ten feet by 
     
     three feet, the other much smaller. 
     
     The plants were about 8 « 14 inches in 
     
     height, with the stem leaves in two's, opposite or nearly so, with three leaflets 
     
     each. The blooms, six to ten per plant, were about onehalf inch in diameter and 
     
     arranged in an irregular loose cluster. The color of the petals, when collected, 
     
     could be described as a faded pink. The root stalks were horizontal, fleshy, and 
     
     scaled. Identification was verified by.Dr. Catling, a taxonomist at the Central 
     
     Experimental Farm, Ottawa. 
     
    

    
     Oddly enough, this plant belongs to the Cruciferae, a family that gives 
     
     us many of our bad weeds: Wild Radish, Stinkweed, several species of Wild Mustard, 
     
     and many others. 
     
    

    
     How about the name, Dentaria diphylla? Dentaria must surely be associated 
     
     with teeth, while diphyZZa refers to the paired leaves. 
     
    
   
   
    
       
     
    
   
   
    
       
     
    
   
   
    
       
     
    
   
   
    
       
     
    
   
   
    
     WANTED: INFORMATION ON MISSING CANNON 
     
    
   
   
    
     In 1901 the Natural History and Antiquarian Society of P.E.I. placed a 1758 
     
     Louisburg cannon in Queen Square in Charlottetown. It is thought that this 
     
     cannon was located south of the old Post Office Building in Charlottetown, 
     
     until sometime prior to the construction of the Confederation Center. 
     
    

    
     Since the present day Natural History Society can be considered the suc- 
     
     cessor to the earlier group, we are interested in any information on the 
     
     current whereabouts of "our" cannon. We are also interested in learning 
     
     what has become of the collections of natural history specimens belonging 
     
     to the earlier group. These included such items as the Gordon herbarium; 
     
     collections of rocks and minerals, insects, shells, leaves, and woods; as 
     
     well as other miscellaneous items like bear‘s paws and walrus skulls. If 
     
     you can shed any light on these matters, the newsletter editor would be 
     
     glad to hear from you.
