PASQUE FLOWER 



VIRGIN 3 BOWER 



Pasque Flower (Pulsatilla) . The word "Pasque" 

 signifies "Easter"; this is one of our earliest flowers. 

 It is properly a plant of the plains and prairies, and 

 is found in the Park only at the lower levels, on gravel- 

 ed hillsides. The leaves are arranged in a basal 

 rosette; they are very hairy, and in outline resemble 

 those of the windflower, except that the sections are 

 much narrower. From the midst of the leaves rise one 

 or several stems about four inches high, each bearing 

 a single large, cup-shaped, purplish or whitish 

 flower, with from five to seven petals and a mass of 

 yellow stamens within. 



Virgin's Bower (Clematis). This plant occurs 

 in many places, always in moderately moist, well-shad- 

 ed woods and thickets. The leaves are oppositely ar- 

 ranged and shaped much like the leaves of the lilac. 

 The petals of the flower are dark blue or purple, form- 

 ing a cup at the base and their points extending 

 straight forward. This is another early-blooming 

 flower, its season being over before the first of July. 

 Another closely-related species of clematis has very 

 finely-divided, somewhat hairy leaves; it is known as 

 Leather- Cup.
