112 COTi'LEDON NEVADENSIS. NEVADA COTYLEDON. 



recorded in the " Botany of California " as being natives to that 

 State, beyond the boundaries of which none have as yet been 

 found in our territory. The genus seems to have been a wanderer 

 northward from a more southern home; and the different species, 

 therefore, wall not probably prove hardy enough to stand the 

 winters in the gardens of many of the States of our Union, but 

 will require some slight protecdon during the severe season. 

 With this slight care, as Mr. Sargent informs us, it is found of 

 very easy culture, and will probably prove a favorite plant for 

 ornamental gardening. 



The old-world plant has had in its time a large number of pop- 

 ular names, such as Kidney-wort, Renny-wort, Navel-wort, Hip- 

 wort, Shield of Heaven, etc., and some of these are sdll retained 

 by various authors as common names for the whole genus. But 

 as these names are in use for other plants, it seems best to refer 

 to them merely as matters of history. The name Cotyledon has 

 become so incorporated into our language through its use in 

 designating the seed-lobes of plants that it is just as familiar 

 as any common name can be. So it is, perhaps, as well to retain 

 it as a common name, as well as botanical, as we do in Dahlia, 

 Verbena, and many other popular plants.
