330 Mnhlenbergia, Volume 2 



The type, in my herbarium, is no. 8609, collected May 31, 

 1907, on Mt. Hamilton, Santa Clara county, California, on the 

 westerly slope of Copernicus Peak, elevation 4300 feet, in darrip 

 grassy places. Its nearest relative is perhaps P. aphanoptera. 

 Mr. Suksdorf, who has examined a specimen, reports that it is 

 unknown to him.

No. 8458, collected April 25, along the base of the San 

 Bruno hills near Colma, San Mateo county, elevation 400 feet,

 Francisco to Monterey. San Francisco is the type locality. 



MiCROSERis CONJUGENS Greene, Pittonia 5: 7. 1902. 



No. 8537, collected May 30, in Hall's valley, Santa Clara 

 county, elevation 1500 feet, in a grassy field, only one patch 

 noticed. In some respects this agrees with M. melanocarpha^ as 

 it has almost subglobose heads, the achenes broadest at summit, 

 the outer ones villous, but the paleae are paler, narrowed above. 

 Some of the heads appear to be destitute of pappus. The type 

 was collected at Byron Springs, Contra Costa county.

No. 8510, collected May 7, on the banks of Los Gatos creek 

 near Campbell, Santa Clara county, elevation 200 feet. A com- 

 paratively common shrub on stream banks, usually in gravelly 

 bottoms from Butte county southward, the branches slender and 

 wand-like. Greene apparently considers this the same as B. 

 glutinosa.
