210 PLANTS GROWING IN LIGHT SOIL. 



RUE ANEMONE. 



Syndesmon thalictroldes. 



This is a very similar plant to the wind-flower and is often 

 found growing beside it ; especially when the chosen haunt is 

 about the roots of an old tree. Its flowers are smaller and 

 they grow in umbels at the end of the scape. The leaves are 

 rounder and less divided. Although it is sometimes found of 

 a rosy hue, its usual colour is white. Like the wind-flower it 

 is very perishable. 



THIflBLE-WEED. (Plate CIX.) 



Anemone Virginiana. 



FAMILY COLOUR ODOUR RANGE TIME OF BLOOM 



Crowfoot. Greenish, white. Scentless. General. A II summer. 



Flowers : terminal ; solitary ; borne on long flower-stalks. Calyx : of five 

 greenish petal-like sepals. Corolla: none. Stamens: numerous. Pistils: 

 numerous. Fruit: thimble-shaped; a head of achenes. Leaves: opposite; 

 and from the base deeply cleft ; the divisions again cleft and toothed. Stem : 

 tall ; smooth. 



The tall, stiff stalks of A. Virginiana are very noticeable in 

 the open woods and in many dry meadows. It is best known, 

 however, by its odd, thimble-shaped fruit. 



TALL LARKSPUR. 



Delphinium urceolatum. 



FAMILY COLOUR ODOUR RANGE TIME OF BLOOM 



Crowfoot. Blue or purple. Scentless. Penn. southward July, August. 



and westward. 



Flowers : downy ; loosely clustered in a terminal raceme. Calyx : of five 

 irregular sepals, one being prolonged into a large spur. Corolla: of four 

 petals in pairs ; the upper pair projecting backward long spurs which are en- 

 wrapped in the spur of the calyx ; the lower pair raised with short claws. 

 Stamens: numerous. Pistils: three, forming in fruit as many erect pods. 

 Leaves : alternate ; palmately divided into three, or five divisions. Stem : 

 three to five feet high. 



The larkspurs form en masse an exquisite bunch of blending, 

 beautiful colours. They are dignified flowers and until ex- 

 amined critically appear to be symmetrical. Their organs, 

 however, are all irregular.
