the latter it may be distinguished by its habit, its more or less 
turbinate calyx-tube and the calyx-segments, which are triangular- 
ovate and about as long as the tube. In Saaifraga Pennsylvanica 
the calyx-tube is campanulate, the segments ovate-lanceolate or 
ovate and twice as long as the tube. The petals of the new spe- 
cies are oblanceolate or nearly linear, while those of its eastern 
relative are lanceolate or linear-lanceolate.

Saxifraga Bongardi Presl; Engler, Monog. Sax. 135. 1872. 
This is one of our northwestern forms that has usually been 
included under Saxifraga leucanthemifolia (S. Michauxi). It is 
more closely related however to the old world S. sée//aris, but is 
nearer the Alleghenian S. Michanxii than any of the several west- 
American species of the subgenus Avabidia that have so persis- 
tently been referred to the Alleghanian form. 
SAXIFRAGA FERRUGINEA Graham, Edinb. Philos. Journ. : 349 
1829. 
This is another Aradidia of the Northwest. It is apparently 
very rare and has usually been referred to a variety of S. Michauai 
(S. Zeucanthemifolia Michx.) or included in that species. Some of 
its distinguishing marks are the low stunted stature, the reddish- 
brown tomentum and the short few-flowered one-sided corymb. 
The only recent collection appears to be that of Dr. G. M. Daw- 
son, made on the Queen Charlotte Islands in July, 1878. 
SAXIFRAGA NUTTALLII. 
Saxifraga elegans Nutt.; T. & G. Fl. N.A.1: 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. rei
