Some interesting species are described in the September No. 

 of the Bulletin of the Torrey Botanical Club (1907) under the 

 title of "New western Species of Gymnosporiangium and Roes- 

 telia," the same being Gymnosporangium betheli n. sp. ("without 

 doubt the most injurious to the cedars of all the species") ; Gym- 

 nosporangium durum n. sp. (produces "a very regular, nearly 

 globose, hard, woody gall") ; Gymnosporangium inconspicuum 

 n .sp. ("a very inconspicuous species; the small pulvinate sori 

 breaking forth between the leaves soon become gelatinized and 

 form a film over the surface of the leaves"). The Roesteliae are 

 R. betheli n. sp., R. harknessiana Ellis & Ev. n. sp.. and R. Hark- 

 nessianoides n. sp. 



Whetsel, H. H. 



A lecture on "Some Bacterial Diseases 0/ Plants: Their Na- 

 ture and Treatment," delivered before the Massachusetts Horti- 

 cultural Society [published in the Transactions for 1907], with 

 stereoptican illustrations, classifies the diseases as Blights (Fire 

 Blight of Pears, etc., Mulberry Blight, Walnut Bacteriosis, Al- 

 falfa Blight, Bean BHght), Rots (Black Rot of Cabbage, etc., 

 Soft Rot of Turnips, etc.), IVilts (of Cucumbers, squashes, and 

 melons, of potatoes, tomatoes and egg plant ,of Sweet corn, of 

 Tobacco j. Galls (of Olive and Oleander, and root galls or nod- 

 ules of Legumes). The annual history of the Fire Blight is fully 

 given ; the fact is emphasized that the blight bacteria are never 

 carried by the wind and they do not exist in the soil ; the milky 

 drops of a sticky fluid oozing from diseased tissues transported 

 by flies and other insects explains the inoculation of the host 

 plants.
