These researches were undertaken with a view to working out certain little known phases of the life history of our local species of dandelion, and particularly with a view to confirming or disproving the following widely accepted conjecture of Raunkjiaer;
"Species Danicae Taraxaci castratione agamice propagari demonstratum est; species onmes Taraxaci semper parthenogenetice propagari verisimile est."
The problem has been found to involve difficulties and obscurities which will require considerable time to effectually disentangle, but results have already been secured which we believe ourselves justified in setting forth.
During the work we have been much in debt to the late Dr. Charles E. Bessey for his cheerfully given and suggestive help, as well as to his associates and to Dr. Florence McCormick for kindly aid.
