Rydberg, a considers this distinct from T. elatum under the name of Therofon occideniale. 



A careful reexamination of the above material and much more leaves our previous con- 

 clusion unchanged. The plant of California, T. cincinnatum Rosendalil & Rydberg loc.

 racemiform and curved pedicels. This is said to range from Washington to California, but 

 we have seen specimens only from California.
