178 AGRICULTURAL BOTANY 



There is a simple free pistil which becomes a legume, 

 or pod. 



The characteristics of this family may be summarized 

 as follows : 



1. Papillionaceous corolla; 



2. Ten diadelphous stamens; 



3. One simple pistil becoming a legume or pod. 

 Umbellif erae, or Parsley Family. Many of the 



common garden plants and some common weeds are 

 representatives of this large family. The carrot, pars- 

 nip, celery, parsley, and chervil are used for food. 

 Anise, caraway, coriander, dill, and cummin furnish

Umbel-bearing plants have : 



1. Hollow stems; 



2. Flowers arranged in umbels;
