acute, a lialf shorter ; upper lip of the small dull-white corolla 2-lobed, about 
equaling the palate ; capsule globose, 1-2" in diameter, somewhat oblique, 
terminated by the short straight and very slender style ; seed deeply reticu- 
lated. — Flowers 2-3^' long. Approaching nearest to A. vagans, Gray, which, 
however, has the flowers and fruit twice larger, the capsule more oblong and 
pointed, the persistent style long and deflexed, the petioles considerably 
shorter and the corolla more saccate. Collected by Stretch in Washoe Valley, 
and not rare in tlie dry valleys of Western Nevada from the Washoe to the
