Notes on Rosaceae—VII* 
PER AXEL RYDBERG 
ALCHEMILLA 
In the North American Flora this genus is taken in a narrow 
sense, 7. e., as Linnaeus originally understood it. The genus 
Aphanes L., which was merged in Alchemilla by Scopoli, differs 
not only in the habit, being leafy-stemmed annuals, instead of 
scapose perennials with rootstocks, but the stamens are usually 
solitary, rarely more numerous, and opposite to one or more of 
the sepals, instead of being 4 and alternate with the sepals. The 
disk in the throat of the hypanthium, so characteristic of the typical 
Alchemillas, is almost obsolete in A phanes. 
The so-called Alchemillas of America are perennials, some of 
them in habit not so unlike the Old World species; but in all the 
stamens are only 2 and inserted on the inside of the disk instead 
of the outside, and the anthers extrorse instead of introrse. For 
these the subgeneric name Lachemilla of Focke was adopted, 
except for one species of exceptional habit, which was made into a 
distinct genus Zygalchemilla. 
All the species of true Alchemilla have their home in Europe. 
Only five of them are either adventive or naturalized on this side 
of the Atlantic and all are confined to the northeastern corner of 
North America. 
Alchemilla alpina L. ranges in America from Greenland to the 
island of Miquelon and the White Mountains of New Hampshire.
