of the corolla. The fruit is a dry two-celled 

 and two-seeded capsule, which opens with two 

 valves, as shown at c, each valve having a 

 narrow dissepiment down the middle : the shape 

 of the seed is shown at d. The leaves are simple, 

 opposite, and entire ; and the branches are 

 filled with pith, which may easily* be taken out 

 and the branch left hollow like a pipe ; and hence 

 the generic name of Syringa, from Syrinx a pipe. 

 The Ash (Fraxinus excelsior) differs so much from 

 the other genera as to seem scarcely to belong 

 to the same order. The flowers are without any 

 petals, and frequently without any calyx ; and 

 some of them, which are called the female 

 flowers, have no stamens, while others, which 

 are called the males, have no pistil. Some of 

 them, however, have both stamens and pistil.
