A very pretty species, once common on the highest prai- 

 ries of the northern portion of the state. Being the first of 

 the vernal flora to unfold its flowers above the dead grass, 

 as is its usual habit, it presents a striking and wel- 

 come object in early spring, turning the brown and 

 sear hills to beautiful roseate tints. The plow has 

 played havoc with the prairies and this species lingers 

 by the waysides or in open upland thickets and out of way 

 places which have been untouched by the tillers of the soil. 

 It has long been called the American or Nuttall's Pasque 

 flower. In portions of the state it is called Easter lily. 

 The flowers open in March or early April immediately after 

 the melting of the snow and are mostly fallen before May,
