SAXIFRAGA NUTTALLII.
Saxifraga elcgans Nutt.; T. & G. Fl. N.A. i : 573. 1840. Not Sternb. 1832.
Little was known of this beautiful and most delicate Saxifrage until it was rediscovered in Oregon in 1871 by E. Hall (156). There is a good and ample specimen of Nuttall's type in the Co lumbia University Herbarium. Mr. Howell has lately found it at three localities in Oregon.
