No. 8587, collected May 30, at Smith Creek at the foot of 

 Mt. Hamiltou, Santa Clara county, elevation 2100 feet, growing 

 in grassy places abont thickets in rather rich soil, the exposure 

 northerly. Also found the following day on the western .slope 

 of Mt. Hamilton, elevation about 2800 feet. It was also noticed 

 here and there about Los Gatos and on Stevens creek, but only 

 a few plants at any one place. On Mt. Hamilton it grew in 

 colonies. It blooms later than D. capitaiiim^ that species com- 

 monly being almost past flowering when this begins, and is 

 also easily distinguished by the more elongated and racemose 

 heads, the long outcurved staminodia colored like the flower, 

 deeply bifid. 



Tritrleia laxa Benth. 



No. 8468, collected April 27, on open grassy slopes in the 

 hills back of Alum Rock Park, Santa Clara county, elevation

 let blue flowers. It grew in colonies in stiff black soil.

 No. 8476, collected April 27, back of Alum Rock Park, 

 Santa Clara county, on steep gravelly slopes among a scattered 

 growth of trees and shrubs, the exposure eastern. The flowers 

 are purplish tinged, as seems to be the case in all specimens from 

 the Coast Range. Douglas no doubt collected the type near 

 Monterey, as it is common there in grassy pine woods.
