 solitary or in small clusters; petals i/^ inch long; carpels 6 to 10, triangular, 

 attached by a straight edge to the slender axis. 



Saline or subsaline soils, 5 to 4000 (or 6000) feet: interior valleys (both cis- 

 montane and transmontane) throughout California and toward the coast south- 

 ward. North to Washington, east to Texas, south to Mexico. May-Sept. 



Geog. note. — On the open plains and low foothills where the soil is more or less alkaline, Sida 

 hederacea is, in the dry season, one of the most common and widespread species of the interior 

 valleys. On account of its deep-seated roots it is often a pest in orchards where cultivation 

 multiplies it, although it is not shade-tolerant. In such places it is knoA\'n as White-.weed. On 

 flood-plain valley floors its taproots usually descend to the water table. It is a honey bee plant 

 of importance to apiarists. In the Imperial Valley it is called Sniffle Weed, with Snuffle Weed 

 as a variant.
