  UCD150823  Orcuttia tenuis Beecher Crampton Date Unknown s.n. Shasta California, Shasta County, east of Redding. Found with Beecher Crampton unprocessed specimens and labeled in 2014. Plant was pressed in a Sacramento Bee newspaper published in 1965 and so does not correspond to other Crampton collections. These plants were probably part of one of his earlier collections of the species and separated into the 1965 newspaper at a later date. Comment
