Fig 89. Petal of 



Lychnis, n, the 



claw ; p, the limb ;

Some of these 



Fig. 90. 

 Gamopeta- 

 lous corolla, 

 showing limb 

 and tube, sal- 

 ver shaped. 



But can you find a primrose, or a 

 red or white dead nettle ? When 

 you pull off the corolla from either of 

 these you find that it is all joined 

 together in one piece. And so this kind 

 of corolla is called " gamopetalous" ' 



The upper expanded 

 part is still called the 

 "limb" but the lower 

 narrowed part is called 

 the " tube " (Fig. 90). 

 gamopetalous corollas are called "labiate, 

 or lipped (Fig. 

 91). If the lips 

 are open, they are 

 called ringent+or gaping, as in 

 the dead nettle ; if the lips are 

 closed, as in the snap-dragon, 



they are "personate"^ Other words 

 are used to describe gamopetalous 

 corollas, such as rotate^ or wheel- 

 shaped, when the limb is spreading 

 and the tube is short, compare speed- 

 well ( Veronica) and elder (Sambucits); 

 salver-shaped if the tube is long, as 

 in the lilac and the primrose ; 

 campanulate j \ or bell-shaped as in the 



Fig.92.-Campanulate. 



* From the Greek " gamos" marriage and petals.
