SEEDS GROUPED BOTANICALLY 
'J'he groupings as given l)elow^ are based upon the “seeds” as 
they aj)pear in commercial samples. The term “seed” used com- 
mercially may refer to either a true seed, botanically, or to a true 
seed plus other flower parts, such as ovary wall, involucre, calyx, 
etc. Thus a fruit, sometimes commercially known as a “seed”, 
may occur as a caryopsis, achene, nutlet, utricle, and rarely as a 
druplet, berry, or follicle. Some genera may occur in more than 
one grouping, as for example, Cenchrus and Chenopodium.
