160 FLORA OF MOUNT DESERT. 



CALLA, L. WATER ARUM. 



C. palustris, L. WILD CALLA LILT. 



Kare. Near Northeast Harbor (F. L. Temple) ; The Heath, 

 Great Cranberry Isle (Arnold Greene, Kedfield). 



SYMPLOCARPUS, Salisb. SKUNK CABBAGE. 



S. foBtidus (L.), NUTT. 



Swamps ; rare. Cranberry Isles (H. C. Jones, Hand, Red- 

 field) ; Sea Wall and vicinity (Band). So far as at present 

 known the distribution of this species is very peculiar. There 

 seems to be no good reason why it should be confined to such a 

 limited area. It may be noted that a slight elevation of the 

 coast line would connect the Cranberry Isles, where it occurs 

 most frequently, with Mt. Desert Island at the Sea Wall and 

 vicinity, where it also occurs. 



ACORUS, L. SWEET FLAG. 

 A. Calamus, L. 



Low grounds ; rare. Near head of Doctors Creek ; near 

 Otter Creek (Eedfield) ; on the "Overflow Brook," Soinesville 

 (E. & E.). 



ALISMACEJE. WATER-PLANTAIN FAMILY. 



SAGITTARIA, L. ARROWHEAD. 

 S. variabilis, Engelm. 



Common in shallow water or wet places. Very variable; the 

 various so-called varieties or forms apparently passing into one 

 another by intermediate forms. 



Forma hastata. 



Common. 

 Forma obtusa. 



Somes Stream (W. H. Dunbar, E. & E.).
