celled anthers which contain pollen. Each of 

 the six stamens contains a filament. In the 

 centre is a separate mass that could be en- 

 closed in a six-sided figure. This is the ovary, 

 but only the upper portion, without ovules. 



The illustration (Fig. 39) is from a photo-

Virgin's Bower. 



(Clematis vitalba.) 



The Clematideae are well known for their 

 ornamental plants. Almost all the genera 

 have species which are cultivated for their 

 great beauty. They are not endowed with 

 sweet-scented flowers, neither have they the 

 insect-loving honey. Still, the insects visit 

 them for their pollen. The clematis is a 

 twining shrub belonging to the Eanunculaceae, 

 among which they are known by their single- 

 coloured calyx without petals, and by the long 

 feathery tail attached to their single-seeded 

 carpels.
