100; Laphamia peninsularis Greene Bull. Cal. Acad. i, 8. 
Through the courtesy of Mr. W. Botting Hemslev 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 = not, so far, been found 
north of San Quintin. 
The shape of the akenes, rendering it a somewhat aberrate” 
- Peritvle, is responsible for the circumstance of its having 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 most of the other species 
the flowers of ?. rotundifolia seem to be largely unfertilized, the 
akenes of the greater number being white and inane.
