PARSLEY FAMILY UMBELLIFERAE 
Many species in this large family have flowers so nearly 
alike that to identify the plants with certainty one must 
have the fruits. The flowers are usually in umbels and the 
leaves are in most cases compound, with the bases of the 
petioles expanded or sheathing the stem. 
Some members of the family are poisonous, as is the 
Poison Hemlock, which the ancient Greeks used to kill 
prisoners and which was the death potion of Socrates. 
Others are very valuable as garden vegetables, such as 
Celery, Parsnip and Carrot. 
The following key is intended only for the 14 genera 
given place in this book; for the remaining species stand- 
ard reference works will be required.
