2. COLLOMIA, NuM. 



1. COLLOMIA LINEARIS, Nutt. 



Hab. Columbia and Kooskooskee Rivers ; eastward to the Upper 

 Missouri. 



2. COLLOMIA GRANDIFLORA, Dough 



Hab. Columbia River and its tributaries in Oregon and Washington 

 Territory ; also around Puget Sound. 



3. Collomia gracilis, Dougl. in Hook. 



Hab. Gray's Harbor, Puget Sound, and Upper Columbia; south- 

 ward to California and New Mexico. 



4. Collomia linoides, Nutt. 



Collomia linoides, Nutt. in Jour. Acad. Philad. n. ser. 1, 159. 



Hab. On the Walla- Walla River, Washington Territory. — Plant 

 about a foot high, with numerous upright branches. Lower leaves often 

 pinnately 3-5-parted, the divisions narrowly linear ; upper stem leaves 

 entire, narrowly linear, erect. Flowers racemose on the branches, 

 the pedicels very short. Calyx campanulate, 5-cleft nearly to the 

 middle, the lobes narrowly oblong, abruptly tipped with a short point. 

 Corolla pale purple, scarcely 2 lines long, the tube slender and a little 

 longer than the calyx, lobes of the border oblong, obtuse with a mucro. 

 Style shorter than the tube of the corolla, the extremity 3-cleft. Ovary 

 with a single ovule in each cell. I have not seen Nuttall's specimens 

 of his G. linoides, but our plant seems to be the same as a Collomia found 

 by Fremont in his second journey; probably somewhere in the Rocky 

 Mountains. [This is Oilia minutiflora, Benth. in DC. Prodr., and is 

 referred to that genus in the revision of Fblemoniacece by A. Gray.]
