Abstract

In the progress of some cytological studies of pollen tube formation, fertilization and related events, I became interested in the cytology of hybrids, and determined to make some crosses for the sake of material for a cytological examination of fertilization between parents of different species. Some experience with hand pollination of Iris suggested the choice of that genus for my experiment. A survey revealed the fact that of species at my command, there was no pair that have been reported to produce hybrids. Iris pseudocorus and Iris versicolor were available. Their near relationship made it seem likely that crossing might be effected, although, so far as I can learn, no hybrids having these parents are known. W. R. Dykes in his magnificent book on "The Genus Iris," which was published in 1912, makes the positive statement that he found no record of that cross having been productive.
