(Botan. Gazette, xi., pp. 189, 190.) 
Mr. Roland Thaxter has continued Dr. Farlow’s cultures of 
_ spores of the Gymnosporangia upon young plants of Amelanchier. 
Those of G. clavipes, C. and P., were followed by R. aurantiaca,

of G. clavarieforme, DC., by R:,lacerata, Fr. 
Rubus deliciostis.—The Odor of. (Gard. Chron., xxvi., p. 50.)

this showy western bramble is compared to that of bleaching

plants grown in England bear white flowers. At Kew it blooms 
abundantly but never. matures any fruit.

This disease is caused by the growth of the fungus Z7//etia . 
strieformis, Westd., which occurs in Europe in the leaves of 
several other grasses, and has been noticed by Professor Trelease 
in Wisconsin on Elymus Canadensis, var. glauctfolius, and in 
Massachusetts on 77iticum repens. It was especially destructive 
to Timothy in parts of Wisconsin in the spring of 1883 and 1884.
