 Cascade mountains, Oregon ; lat. 44° 30'. 



The flowers of this plant are erect, but when the seed is nearly ripe the stalks which support 

 the carpels curve downward and outward until the carpels themselves rest on the ground 

 accurately inverted. The dehiscence of the carpels takes place at the summit, and the bean-like 

 seeds are carefully deposited on the "ground and roofed over by the persistent carpels, probably 

 through the winter. 



On the banks of Mpto-ly-as river, near the base of Mount Jefferson, Oregon, at an altitude of 

 5,000 feet, in September, I found large surfaces covered with this plant, which had already been 

 touched by the frost. Of the hundreds of clusters of pods, all were inverted and resting on 

 the ground, completely covering the seed, which had generally fallen out. The carpels are from 

 3 to 5 in a cluster, the number varying in the same plant.
