VOl. XIX PP. 155-158 12, 1906 NOVEMBER PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON NE'V PLANTS FROM THE GREAT BASIN. BY AVEN NEL 01 AND P. B. KENNEDY. A desert flora i always intere ting to the student. The hard conditions that prevail, produce variation or elimination. The unu ual ecological factors give rise to a urpri ingly larg number of forms that . em to have character which are both fixed and li tinct. Prof. P. B. K enn dy, of the University of Nevada , Reno, is favorably located for studying ju t such a flora. Th e Gr at Basin has interested. others and much is known of it vegetation, but that vast area will long r emain a fruitful fi ld of inquiry. 1\1r.
