In one strain (1213, fig. 19c) a plant occurred in which the attachment constriction of one of the members of the pair was nearly median, in the other member it was distinctly nearer the proximal end. In another plant of the same strain (fig. 19b) in both members of the pair the constriction was median. In plants of two other strains (1483 and 1894) each mem- ber of the pair had the constriction nearer one end of the chromos

Satellites have been seen in nearly every species but only in some of the 22-chromosome forms was it possible to determine their number, 4 satellited chromosomes having been established in several 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 Hollingshead, Lillian, 1900-; Babcock, E.
