No. 7921, collected June i, at the water's edge on the Sac- 

 ramento opposite Upper Soda Spring, Siskiyou county. Mr. 

 Holm says it is "very rare." The type was collected by Bolan- 

 der, the range given "in the Coast Ranges from San Francisco 

 Bay to Ukiah." It looks remarkably like the plant figured as 

 C. Wilkesii under plate 17 of the atlas to volume 17 of the U. 

 S. Exploring Expedition. On page 477 of that work it is re- 

 ferred to C. laciniata Boott, but is not described, unless the ex- 

 planation of the plate is taken as a description. It was collected 

 on the "banks of the Sacramento."
