543. FALSE LOOSESTRIFE; MANY-FRUITED LUDWIGIA 



LUDWIGIA POLYCARPA Short & Peter ' 



Not common ; in moist ground opposite Overmyer's field ; also 

 in wet soil by the birch swamp. An inconspicuous plant. 



544. SEED-BOX; RATTLE-BOX 



LUDWIGIA ALTERNIFOLIA L. 



Scattered, in marshy places; near the birch swamp and north 

 of Lost Lake. The plants when in flower are quite conspicuous, 

 the bright yellow blossoms, which drop their petals when shaken 

 or shocked, catching the eye for a considerable distance. The plant 

 is an attractive object in autumn when the leaves and sepals turn 

 red, and in the dead of winter when the shapely seedboxes with the 

 square lid, arranged orderly on the stalk, project above the snow. 



545. LINEAR-LEAVED WILLOW-HERB 



EPII.OBIUM LINEARE Muhl. 



The presence of this species is attested by an herbarium speci- 

 men collected by Dr. Scovell August 26, 1900. No definite record 

 can be given of its occurrence, as the species of willow-herb are not 

 especially conspicuous and are difficult to recognize in the field. 



546. PURPLE-LEAVED WILLOW-HERB 



EPILOBIUM rOLORATUM Muhl. 



A few plants along the lake shore near Green's, mixed in with 

 cockleburrs and grasses. Abundant in a low swale near Murray's, 

 almost wholly occupying the central portion. Common in low open 

 places. More conspicuous in fruit than in blossom, the silky seeds 

 escaping from the pods producing a cottony effect. On a trip to 

 Bass Lake August 14, 1906, whole stretches of landscape in low 

 grounds were whitened by the seed-silk of these plants. 



547. COMMON EVENING-PRIMROSE 



OENOTHERA BIENNIS L. 



An occasional beach plant, as at Long Point near the Barnes 

 cottage and beyond Norris Inlet. A few plants on the depot 

 grounds near the lake. The greater number of plants, however, 

 grow back from the lake in dry ground. There are good patches 

 in open lots on Long Point, and the old sandy fields about the lake 

 bear numerous scattered plants. Common on the east side by 

 McOuat's.
