SAXIFRAGA FERRUGINEA Graham, Edinb. Philos. Journ. : 349. 1829.
This is another Arab/dia of the Northwest. It is apparently very rare and has usually been referred to a variety of S. Michartrii lerecanthenrifolia 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.
