    VOL. XXV.—NEW SER.] On the Life-History of certain British Heterce- cismal Uredines. (The Ranunculi .fficidia and Puccinia Sehceleriana.) By diaries B* Plowright. In the following communication, the life-histories of five ^ species of Uredines which during the past three years have been investigated are detailed, together with an enumeration of the experimental cultures performed in connexion therewith, by which it will be seen that the conclusions have not been hurriedly arrived at. It may be thought that many of these cultures are needless repetitions, but I have found myself com- pelled to differ in certain points with the eminent Continental botanists who have made this subject their special study, and to whom, indeed, we owe all the information we at present have concerning it. It will be seen that these differences are mainly connected with the host plants upon which the various Uredines in question occur. It is hoped that my eminent confreres wiil recognise the fact that my investigations have not been made in any spirit of captious criticism, but rather with the object of verifying and amplifying the discoveries they have already made. Hence when any statement of theirs has been found to accord with my own results, this particular culture has not been repeated many times. For example, with Uromyces dactylidis twenty-seven experiments were made altogether, but of these only five were confirmatory of SchroteFs statement as to its iEcidium occurring upon Ranun- culus bulbosus, for the simple reason that Schroter's statement on this point is correct, and it would have been a
