Spirea Aruncus claims a place in the list of disjoined species. 
It occurs in the Catskill mountains, New York, and southward 
along the whole extent of the Alleghanies; but here it ranges 
no farther northward. It is not a Scandinavian plant; but from 
France it extends eastward through Northern Asia to Kamts- 
chatka, and thence to Sitcha and the mouth of the Oregon.
