 it ends in a loose raceme of 4 to 8 showy flowers. The spe-

 inner segments (petals) broad, narrowed to a claw above 

 which is a conspicuous gland or pit. Stamens 6, on the base 

 of the segments. Ovary 3-angled, capped by 3 sessile stig-

 from the Hetch Hetchy to the Mariposa Grove and may 

 rarely be found as high as 7500 ft. alt. Its blossoms appear in 

 June.

 near Groveland. It has clear-yellow flowers about x / 2 in. long, 

 the petals densely covered with yellow hairs.
