Order IV. . Decandri^., 
In this order the stamens are usually divided into 
nine in one parcel, with a single one separate, and the 
genera are distributed into six sections, in the first of 
which the stamens are all united, as in the common 
broom ; in the second the stigma is downy, as in JPisum 
or Pea, and Vicia or Vetch ; in the third the pod is 
nearly two-celled, as in Astragalus or Milk-vetch j in 
the fourth the pod has scarcely more than one seed, as 
in Trifolium or Trefoil ; in the fifth the pod is nearly 
jointed, as in Hedysarum ; and in the sixth the pod is 
one-celled and many-seeded.
