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.
