Observations on Physalacria inflata (Schw.) Peck, 
by Jessie M. Polley, Minnesota Botanical Studies, 3:323-8, PL 
LIII, Oct. 18, 1904, treats of the rare and interesting fungus 
that was named Leotia inflata by Schweinitz in 1822. A new 
study of the plant from material collected at Detroit, Minnesota 
was made by Miss Polley. 
J. C. Arthur in Leguminous Rusts from Mexico (col¬ 
lected by E. W. D. Holway), published in the June No. of the 
Botanical Gazette, 1905, enumerates 37 species. Of these the 
following are new species: Uromyces rugosa, U. montanus, U. 
cologaniae, U. clitoriae, U. bauhiniicola, Calliospora holwayi, C. 
farlowii, C. diphysae, Uredo aeschynomenis, Revenelia lysilomae, 
R. gracilis, R. pithecolobii, R. inconspicua, and R. pulcherrima. 
A new genus of Rusts,namely, Calliospora is proposed, with 
the following diagnosis: Teleutosori arising from beneath the 
epidermis, soon naked; teleutospores 2-celled by transverse parti¬ 
tion, wall colored, with an external layer which swells in water; 
germ pores 2 in each cell, lateral. Aecidium and uredo wanting. 
Spermogonia arising from beneath the cuticle, conical. 
Contributions to the Biology of Rhizobia, IV: two 
coast Rhizobia of Vancouver Island, B. C., by Albert Schneider 
is published in the Botanical Gazette for August 1905, and relates 
to forms found in the beach vetch, Lathyrus maritimus Bigel., 
and the beach clover, Trifolium heterodon Gray. 
The V. Contribution to the Biology of Rhizobia by 
Albert Schneider, published in the Botanical Gazette for October 
1905, deals with the isolation and cultivation of Rhizobia in arti¬ 
ficial media. 
Rusts on Compositae from Mexico is an important con¬ 
tribution to the mycology of that region, by J. C. Arthur in the 
Botanical Gazette for September 1905. They are mostly the 
collections of Prof. E. W. D. Holway, the list containing 54 
species. The new species described are Coleosporium dahliae, 
C. steviae, Dietelia eupatorii, D. vernoniae, Uromyces senecioni- 
cola, Puccinia senecionicola, P. globulifera, P. gymnolomiae, P. 
caleae, P. axinophylli, P. noccae, P. jaliscana, P. diaziana, P. 
semi-insculpta, P. egregia, P. zaluzaniae, P. concinna, and P. 
paupercula. 
Fertilization in the Saprolegniales, by B. M. Davis, in 
the Botanical Gazette, January, 1905, is mainly a critical discus¬ 
sion of Trow’s reaffirmed conviction that a sexual act is present 
in the water molds, etc.; with then the remark that much more 
work must be done both on the Saprolegniales and Peronospo 
rales before some of the points suggested by Trow’s paper will 
be established.
