 1907, near the summit of Mt. Hamilton, Santa Clara county, 

 California, elevation 4000 feet, growing in grassy places under 

 oak trees on a westerly slope. Its nearest le^.ative is perhaps /,. 

 piibcriilus^ from which it differs in its rigid erect growth, paler 

 more pnbesceut leaves and tawny flowers. In habit it is like 

 the northern L. vestihts^ but that lias stipules nearly as large as 

 the leaves, and large purple flowers on short peduncles. 



Two specimens of this species are in the herbarium of the 

 University of California, one from Mt. Hamilton collected by 

 Greene, the other from dry hillsides, Mt. Diablo, April 30, 1862, 

 from the State survey collection. j^. :;ijii.} ■ - •.;, -s^-.

 No,- 8469, collected April 27, back of Alum Rock Park, 

 Santa Clara county, on hillsides near shrubs, elevation about 

 800 feet. This species as generally accepted is no doubt an ag- 

 gregate. The number here cited has a very short slender de- 

 cumbent woody stem, the whole plant little over two feet liigh, 

 and is the form common in Santa Clara county on low hills. It 

 .is not a true woodland species; but grows on hillsides, usually 

 about thickets in rather dry places.
