SANGUINARIA CANADENSIS L. 



Common in woodlands, especially on the east side of the lake.

 were pretty badly frozen April 19, 1901. The petals are usually 

 pure white. Some seen near Bloomington, Indiana, had a pinkish

CAMELINA SATIVA (L.) Crantz 



Not common ; a member of the railroad flora, and apparently 

 of recent introduction. In flower along the railroad in front of the 

 Assembly grounds May 18, 1901. 



365. SHEPHERD'S-PURSE 



BURSA BURSA-PASTORIS (L.) Britton 



Like the dandelion and English sparrow, one of the hardy emi- 

 grants found thriving everywhere and at all times and seasons. It 

 is not so much of a nuisance as the dandelion, however; it is easily 

 killed out by cultivation and while sometimes annoying in lawns, 

 it cannot compete with a vigorous growth of grass, and is not so 

 conspicuous or persistent as the dandelion, being an annual. It is 

 essentially a plant of waste places. It is usually one of the very 

 earliest plants to be found in spring, and the latest in autumn. At 

 Lake Maxinkuckee, it was found everywhere in waste places and 

 at all seasons.

566. MARSH WATER-CRESS; YELLOW WATER-CRESS 



RADICULA PALUSTRIS (L.) Moench 



Common in wet places, forming scattered patches. Although 

 abundant in places it never becomes a bad weed, as it is confined to 

 grounds too moist to cultivate.
