Lake Maxinkuckee, Physical and Biological Survey 295 



road south of Outlet Bay. In flower June 21, 1901. Continues in 

 blossom until late in autumn. 



. 296. SOUTHWESTERN PERSICARIA 



PERSICARIA PERSICARIOIDES (H. B. K.) Small 



Apparently rare. A herbarium specimen was collected by Dr. 

 Scovell. The lake region is considerably out of its usual range. 



297. MILD WATER PEPPER 



PERSICARIA HYDROPIPEROIDES (Michx.) Small 



Frequent in low places near the lake; a small patch on a low 

 flat between the road and south shore of Outlet Bay. Noted in 

 blossom in September and October. 



Some smartweed, perhaps this, made great patches of pink cov- 

 ering acres of extent in the Kankakee marshes, where it was said to 

 form the principal food of the mallard duck. In the old channel 

 of the outlet, a mile below the lakes, there was a continuous bed, 

 bordered on both sides by sedges, making a winding stream of rosy

298. SMART-WEED; WATER PEPPER 



PERSICARIA HYDROPIPER (L.) Opiz 



Common about the lake; an abundant weed; because of its 

 greenish blossoms not so handsome as many of the species. 



299. DOTTED OR WATER SMART-WEED 



PERSICARIA PUNCTATA (Ell.) Small 



Common in moist places about the lake. Noted in blossom Oc- 

 tober 10 and still continuing in bloom October 30, 1900. 



300. BUCKWHEAT 



FAGOPYRUM FAGOPYRUM (L.) Karst. 



Occasional escapes from cultivation were seen about the lake. 

 Where it has been grown, this plant, unless removed by clean culti- 

 vation, is likely to persist as a weed, although it never becomes 

 particularly troublesome. 



301. ARROW-LEAVED TEAR-THUMB 



TRACAULON SAGITTATUM (L.) Small 



Growing at Long Point and on both sides of the Outlet. Hardly 

 as common as one might expect. Common in many parts of the
