Grasses

by H. Marshall Ward

[12] This term does not necessarily imply any botanical relationship with the true Millets (Panicum), but merely that the caryopsis is short and broad as in these grasses.

[13] In cases where the “seed" has fallen from the glumes the sample will usually show some of the latter lying loose.
