Two genera of rushes, 

 the wood rushes and the 

 bog rushes are found in 

 Minnesota. The wood 

 rushes are recognized by 

 their habitat and by the 

 position of the bractlets 

 beside the flowers. The 

 bog rushes, while of the 

 same general appearance, 

 commonly produce more 

 seeds in each capsule than 

 do the wood rushes. No 

 little variety exists among 

 the rushes in the shape of 

 their flower-c lusters. 

 Generally they are rather 

 flat-topped, but some spe-

Lilies and their allies. About forty species of plants be- 

 longing to the lily family are known to occur in Minnesota. 



Among them may be men- 

 tioned the trilliums, or wake- 

 robins, the hellebores, the 

 asphodels, the bellworts, the 

 clintonias, the false and true 

 Solomon's seals, the asparagus, 

 the tiger-lilies, the dog's-tooth 

 violets and the wild onions. 

 These plants occupy a variety 

 of habitats. Some, like the 

 asphodels, are to be sought in 

 tamarack swamps; others, like 

 the bellworts and Solomon's 

 seals, in the edges of the 

 woods; others, like the clin-
