780 The American Naturalist. - [August, 
localities, but was generally out of bloom. Mertensia lanceolata D.C. 
was found growing among the short underbrush of the second banks 
in War Bonnet Canyon. 
The weather was too dry for lichens and most of the fungi. Of the 
former, several interesting Cladonize were found together with two or 
three species of Peltigera. On the north slopes of the dampest cafions 
Parmelia olivacea (L.) Ach., and a sterile form of Usnea barbata (L.) 
Fr., grew very plentifully on the pines everywhere. 
Various species of Æcidium and Uromyces occurred generally in 
large quantities ; the most plentiful being Æcidium abundans Pk., Ecid, 
clematidis D.C., Acid. grossularie Schum., Uromyces trifolii f. glycyrr- 
hise E. & E., and also Gymnosporangium clavariforme (Jacq.) Rees., 
L, was found quite plentiful in a small side cafion of the War Bonnet, 
on Amelanchier canadensis. Along the higher lands and buttes above 
the cations Ustilago carices (Pers.) Fück, was found in large quantities. 
Out on the Hat Creek Basin Ustilago hyphodytes (Schlect) Fr., which 
is considered a rare species, occurred in considerable quantities on 
Stipa comata. Several interesting rock forms of lichens were found on 
the rocks cropping out near the edge of the ‘bad lands ;’’ the most 
plentiful as well as the most beautiful being Lecanora rubina (Vill.) Ach. 
and Z. rubina var. opaca. Ach., Fr. and Placodium Sp., near P. elegans 
(Linta) D.C. Many rocks being literally covered by these with a few 
others.—Tom A. Wituiams, Ashland High School, Nebraska. 
Botanical News.—Professor McLaren, of the Maryland Agri- 
cultural College, has had his copies of Gray’s Manual bound in oil 
cloth, a decided improvement over the soft and rather bibulous cloth 
cover usually given the book by the publishers. Now if the margins 
could be trimmed down it would improve it still more. . . . The 
fourth number of the memoirs of the Torrey Botanical Club is devoted 
to a paper by Dr. E. Lewis Sturtevant on ** Seedless Fruits." Sixty- 
one species are mentioned in the paper. The general result appears 
to be thata tendency to seedlessness is an accompaniment of high 
development. . . H. S. Jennings published an annotated list of 
ninety-five parasitic fungi of Texas, in the ninth bulletin of the Texas 
Agricultural Experiment Station.. . . G. N. Best has examined 
(Torrey Bulletin for June, 1890) some of the North American roses— 
those belonging to the group Cinnamomex,—and among other changes 
reduces Rosa arkansana Porter, to a variety of Rosa blanda Ait., as 
R. blanda Ait., var. arkansana (Port.) Best. This reduction, it will be 
remembered, was suggested by Watson five years ago in Proc. Am.
