SYNONYMY OF VARIETIES. 
Many varieties are known by several names. The names here used 
for the recognized varieties are the original names or the name now 
most commonly used or are the new or simplified names, as pro- 
vided for by the code of nomenclature. All other names used for 
the varieties here described are considered synonyms. 
THE WHEAT PLANT. 
The different cultivated varieties of wheat vary greatly in their 
habit, form, and structure, but all are annual grasses. The principal 
parts are the roots, culms, leaves, and spikes. There are two sets of 
roots, the first or seminal or seed roots and the second or coronal 
roots, the latter arising from the crown of the stem. The culm is a 
hollow, jointed cylinder comprising three to six nodes and internodes. 
The upper internode of the culm, which bears the spike, is called the 
peduncle. The leaves are composed of the sheath, blade, ligule, and 
auricle. The spike is made up of the rachis and spikelets. the latter in 
turn comprising the rachillas, glumes, lemmas, paleas, and the sexual 
organs, or the three stamens, and the single ovary with its style and 
stigma. Each of these parts may show distinct characters in different 
varieties. Those characters that do not vary or are not readily ob- 
served are of little value in classification. The root characters, for 
example, which are not apparent, can not be conveniently used, and 
no attention has been given to them in this work. Other characters, 
such as those of the sheaths, ligules, and auricles, are not generally 
used because they show very slight differences in different varieties.
