of genera is largely increased under the new Classification, there 

 are a number of short cuts to aid in naming collections, some of 

 which are given. 



The author shows that although it may seem that there has 

 been "an appropriation of the Schroeterian biological classes, into 

 which every genus was considered to be potentially divisible, / e., 

 heteroforms, auteuforms, opsisforms, brachyforms, hemiforms, micro- 

 forms, and leptoforms, and calling these classes genera, in reality 

 the basis of the segregates which I have recognized, for example 

 Dasyspora with teliospores, Bidlaria with urediniospores and telio- 

 spores, Allodiis with aeciospores and teliospores, and Dicaeoina with 

 all the sporeforms which take the place of the genus Puccinia as 

 now commonly used, rest upon wholly different consideration , 

 having to do fundamentally with the progressive evolution of the 

 rusts, and not with adaptations." This latter view is supported by 

 a brief argument. Other phases connected with the problems involved 

 are also briefly discussed, showing the superiority of the new Classi- 

 fication. Hedgcock. 



Arthur, J. C, Reasons for desiring a better Classification 

 of the Uredinales. (Journal of Mycology, XII. p. 149— 154. Jul. 1906.) 



The many defects of the present Classification of the Uredinales 

 are set forth and reasons are given for a better grouping based on the 

 Position of the genera in a natural System. The nomenclatorial 

 Standing of the aecial stage or phase is upheld for the reason that 

 this is probably according to recent cytological studies the sexual 

 stage of the rusts. It is asserted that the desire for a stable nomen- 

 clature should never stand in the way of improvement in Classification 

 by the segregation of genera to bring out mure clearly the relation- 

 ship of groups of species. The great variety of forms which fall 

 under the genus Puccinia and Urotnyces is shown, setting forth 

 their artificial construction. The author discusses at length a segre- 

 gation of species to show more fully their affinities. Hedgcock.

Butler, O., Observations on some Vine Diseases in Sonowa 

 County, California. (California agric. Expt. Stat. Bull. CLXMII. 

 p. 1—29. 1 pl. 5 fig. May 1905.) 



The results of an investigation of three diseases of Vitis viuifera 

 in California are given. The Red-Leaf Disease is described and its 

 relationship to the Folietage, the Rougeot, and the Anaheim diseases 

 is set forth. It is not considered of parasitic origin, as spraying was 

 used as a probable means towards its control without success. The 

 disease is considered most like the Rougeot, and is supposed to be 

 due to unfavorable physical conditions. A second disease is named 

 the Grape Shrivel, and its chief characters are the shriveling and 

 drying up of the berries, and the browning and death of the leaves.
