158 Elementary Botany 



Anemone, Wind-flower. No corolla present, the calyx 

 either coloured as in the Pasr le-flower, or white as in the 

 Wood-anemone. Flowers in tl j spring; several species cul- 

 tivated in our gardens for their showy colours. 



Aguilegia, Columbine, with its five sepals petaloid, and 

 five petals with spurs twisted up in a horn-like manner. Grown 

 in gardens. 



Caltha, Marsh-marigold (fig. 294). A marsh plant with 

 large flowers, yellow sepals, and no petals. 



(Note, although this and other plants of the order are in- 

 complete, the corolla being absent, yet we place them in this 

 thalamifloral order because their general affinities resemble 

 those of the other plants of the group. The same remark is 

 true of many incomplete plants of other orders.)

Clematis, Old Man's Beard, or Traveller's Joy. A shrubby 

 climber with opposite leaves. The sepals are petaloid (greenish 

 white in the British species), and petals absent. Many exotic 

 Clematis are cultivated for their beautiful flowers. 



Delphinium, Larkspur (fig. 202). Flowers with one sepal 

 spurred. Two petals small and united within the spurred sepal. 

 Stavesacre is obtained from an exotic Delphinium. 



Helleborus, Hellebore. Sepals large and petaloid, petals 

 small and tubular. The Christmas Rose is an exotic Helle- 

 borus. 



Myosurus, Mousetail. Small clawed petals, and carpels 

 arranged in a dense cylindrical spike, whence the name.
