SINGLE AND MULTIPLE GERM BEET SEED. The term seedball,as applied to beet seeds, implies a combinationof seeds into a mass having a more or less rounded appearance (PL I, A); hence, the term ball. can not properly be appliedto the single-germ beet seed(PI. I, B). Each germ arisesfrom a single floret, and whenthe flowers are in clusters oftwo or more (fig. 1) a multi-ple-germ seed arises; where-as, if the flower stands byitself on the stem (fig. 2) a sin-gle-germ seed results. If twoor more single flowers standvery close together but donot arise from the same pointas in the case of flower clus-ters, each will produce a sin-gle-germ seed (PI. II). Evenif the flowers are so close to-gether that the seeds slightlyadhere in the process of de-velopment, they are easilyseparated and readily distinguished as single-germ seeds (PI. Ill, flowerstalk on right hand, end of second branch at left). On the other hand,the component parts of a multiple-germ seed ball adhere so firmly thatthey can not be separated by any known process without great dangerof injuring the germs. It appears, therefore, that the arrangementand distribution of the flowers o
