But if we are careful in the dissection of the parts we will see, on looking close below the pistil on the side of the flowering glume, that there are two minute scales (fig. 334). These are what are termed the lodicules, considered by some to be merely bracts, by others to represent a pe- rianth, that is two of the sepals, the third sepal hav- ing entirely aborted.

To the gramineae belong also the wheat, barley, corn, the grasses, etc. The gramineae, while belonging to the class monocotyledons, are less closely allied to the other families of the class than these families are to each other. For this reason they are regarded as a very natural 507. The sedge family (eyperaceae). Carex.—As a representative of the sedges a species of the genus carex may be studied. If plants of Carex lupulina are taken from the soil carefully we will find that there is an under-.
