THE PLANTS OP THE PEIBILOF ISLANDS. 567 



much larger, leaves more numerous and generally double crenations, the smaller 

 indentations containing a gland, or when simply crenate each crenation gland-tipped, 

 thin, membranaceous in texture, (when dry) paler in color; petioles with margins 

 usually glabrous but sometimes ciliate with a few white hairs. 



Our form, which resembles 0. tetrandrum in the size and shape of the leaves, has 

 8 stamens instead of 4, pui"ple instead of greenish flowers, larger and definite seeds 

 (6 to 10 instead of 30 to 50), stronger-lobed disk, and apparently differs also in its 

 habit." 



Abundant on disintegrated scoria in the interior of St. Paul Island.
