Those developed in the ovary of grandiflora, after pollination by biennis, have the same color as the female parent. The above description is so worded as to emphasize the characters of the grandiflora strains A, B, and D in con- trast to the biennis strains A and B. It should be com- pared with the description of the latter forms to under- stand clearly the conditions that appear in the hybrids, which will now be 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 Bussey Institution.
