while Eritrichium in North America practically disappears in 
Krynitzkia and Plagiobothrys. Later, Professor Greene” defines 
the following genera: Allocarya, Eremocarya, Piptocalyx, 
Sonnea, Plagiobothrys (incl. Echidiocarya), Oreocarya, Cryp- 
tanthe, and Amsinckia. This is the arrangement adopted in the 
Pfhlanzenfamilien. Professor A. Philippi? describes one hundred 
Chilian species in twelve groups under Eritrichium, besides 
recognizing Amsinckia and Plagiobothrys. The one hundred 
species of Eritrichium fall under Allocarya, Eremocarya (?), 
and Cryptanthe. 
In the following tabulation species are grouped under those 
characters which best emphasize the relation of the Chilian to 
the North American species :
