The experience which has led to the writing of this book began in 1929 when, examining a species related to Utricularia gibba, I made an observation of some importance in understanding the mechanism of the trap. This begot a desire to study as many other species of the genus as I could obtain for comparison, primarily to determine the validity of my conclusions. My feeling that research in this field was promising was strengthened by the discovery that the pertinent literature was singularly barren of the information most needed, that is to say, precise accounts of the structure of the entrance mechanisms of the traps. And an examination of much herbarium material, because of the meagreness of the underground parts of the terrestrial types resulting from indifferent methods of collection, forced the conclusion that, even had other difficulties inherent in studying dried material not intervened, it would be necessary to obtain adequately preserved specimens. This meant a wide correspondence and, if possible, extensive travel. The uncertainty of achieving the latter made the former imperative. - Häftad, Engelska, 2020
