The Flowers of the Grass Family f to which the cereals belong, as well as corn, sorghum, sugar cane etc., are quite different from those of most other plants. In this family, the flowers are arranged in little groups, each of which is called a spike- let. What we call a head of wheat is made up of a number of spikelets, one of which is shown in Fig. 53. Fig. 54 shows the spikelet dissected. The two scale-like parts at the base, g. g., are called glumes. The similar pair above, tipped with a bristle (the awn or beard) are called the lower or outer pales or palets (pa'- lets) or flowering glumes — to distinguish them from the * Tanacetum vulgare. t Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Goff, E.
