Genus Saxirraga, Linn. ; (Benth. § Hook. f. Gen. Pl., vol. i. p- 635), 
SaxIrraGa peltata; rhizomate crasso repente, foliis omnibus radicalibus 
longe petiolatis erectis amplis peltatis orbiculatis amb:tu 6—10-lobatis 
lobis inciso-dentatis, scapis nudis elongatis, cymis corymboso-capitatis 
multifloris glandulosis, calycis tubo brevissimo obconico-campanulato, 
‘Sepalis oblongis obtusis, petalis ellipticis obtusis, filamentis subulatis, 
carpellis liberis in stylos breves attenuatis, stigmatibus dilatatis.

One of the largest species of the genus, and a very curious 
one, though far from being as handsome as many others. 
Variable as the foliage of the Saxifrages is, the present is the 
only one known in which that organ is completely peltate, 
and like many other peltate-leaved marsh and water-loving 
plants, this is stated to be found on the margins of streams and 
mn the water itself. I have seen indigenous specimens 
gathered in the Sacramento Mountains by Hartweg, who dis- 
Covered the species ; in the Mendreino county, California, by 
Prof. Bolander, of San Francisco ; and others collected by 
Lobb without a locality. A very singular form, either a 
variety or different species, is in the Hookerian Herbarium 
from Clear Creek in North California; it has the almost 
glabrous cyme broken up into a distantly branched panicle, 
the branches of which have short rounded bracts at the base, 
and has inflated much rounded carpels abruptly terminated 
with short styles; the fruit figured in the “Botany” in the 
United States Exploring Expedition resembles this, and not 
¢ narrower attenuated fruit of Hartweg’s, Lobb’s, and the 
cultivated plants. Engler in his Monograph of Savifraga
