 Through the courtesy of Mr. W. Botting Hemsley of the Kew 

 Herbarium, who has very kindly furnished us a few akenes of the 

 type, the longdoubtful genus Amauria disappears at last from our 

 flora. Exploration of the Peninsula of Baja California has in 

 recent years been prosecuted to so considerable an extent, that 

 the existence at a place so well known as San Quintin of a 

 generic type not found by subsequent botanical visitors had 

 become improbable, and attention was called to its possible 

 identity with some known plant. It has not, so far, been found 

 north of San Quintin. 



The shape of the akenes, rendering it a somewhat aberrant 

 ■Perityle, is responsible for the circumstance of its havfng been 

 named in three different genera. The specific name rotundifolia 

 is much the earliest, indeed Perityle has over Amauria pre- 

 cedence rather than priority. Like mo.st of the other species 

 the flowers of P. rotiindifolia seem to be largely unfertilized, the 

 akenes of the greater number being white and inane.
