SHELDON, JOHN L., Preliminary Studies on the Rusts 

 o f t h e Asparagus and the Carnation; Parasitism of 

 Darluca. (Science. N. S. XVI. 1902. p. 235—237.) 



Inoculations were made mostly in the green-house, with the 

 asparagus rust (Puccinia asparagi DC.) and the carnation rust (Uromyces 

 caryophillinus [Seh.] Schroet.). Inoculations were made by spraying the 

 plants and placing the spores on the moistened leaves and stems. 

 Successful inoculations were made with spores collected December 12, 

 1900, March 28 and April 24, 1901, the spores having survived the winter 

 when protected by the unbroken epidermis of the asparagus. The 

 period of ineubation in the greenhouse varied from eighteen to eight 

 days. Decrease in temperature, number of hours and intensity of the 

 sunlight lengthened the period of ineubation. Increase in these factors 

 shortened it. Vigorous growing plants took the disease much better than 

 those that were doing poorly Successful inoculations were made with 

 uredospores on the prineipal varieties of garden asparagus and on 

 A. plumosus nanus, A. broussonetti and A. v er tic Hiatus. 



In many instances teleutospores have followed the produetion of 

 uredospores giving all stages of the rust from inoculations. The simi- 

 larity of Puccinia asparagi and P. porri on the onion, with the results 

 of the inoeuiations, suggest the identity of the two rusts. Klebahn has 

 inoculated several species of Allium including A. cepa with Mclampsora, 

 producing a Caeoma in each case. Inoculations of several species of 

 Dianthus and Gypsophila with the uredospores of the carnation rust 

 (Uromyces caryophyllinus [Seh.] Schroet.) gave the same results as con- 

 cerns sunlight, temperature, etc. as was obtained with asparagus. The 

 carnation rust is localized instead of being distributed throughout the 

 plant. Certain varieties of carnations are practically immune. 



Experiments with Darluca filum Cast, thought to be parasitic on 

 carnation rust, gave strong indications that it may be parasitic on 

 asparagus. Its saprophytic tendencies were shown by growing it on 

 various animal and vegetable eulture media. P. Spaulding.

dores de Barcelona. (Boletfn de la Sociedad espanola 



de Historia Natural. II. 1902. p. 207—211.) 



The author calls attention to the State of neglect into which the 

 Spanish Cryptogams and especially the Lichens, have fallen; and he 

 publishes a list of 5S species and 9 varieties of Lichens gathered in the 

 environs of Barcelona. A. Gepp (London).
