pllopo-barbato. — La Vergne Park, near Flagstaff, N. Arizona, 1884, 

 Mr. and Mrs. Lemmon. In the inflorescence and flowers this neat

 long) is narrower and more virgate, the corolla smaller, the whole 

 completely glabrous : the leaves are very different ; and the pubes- 

 cence along the whole length of the sterile filament is peculiar.
