 Prodr. 10, p. 372. 



Hab. Spipen River, Washington Territory; on mossy banks.— 

 This is the smallest species of the genus. Our specimens are only two 

 inches high. [They probably belong to M. microphyllus, Benth.]

Hab. On the Columbia River, from Walla- Walla to Fort Okanagan ; 

 a small form. Valley of the Sacramento ; a form with stems a foot 

 or more in length, and diffuse.

 D. latifolius, leptanthus & longiflorus, Nutt. 1. c. ; Benth. 1. c. 



Hab. Valley of the Sacramento, and near San Francisco, Califor- 

 nia. — There can be no doubt that all of Nuttall's species of Diplacus 

 pass into each other by insensible gradations. [It is ascertained that 

 the placentae are really parietal in Diplacus, so that the genus will 

 be maintained.]
