Rydberg : Studies on the Rocky Mountain flora 479 



and DeCandolIe's genus Miltitzia should be restored. The latter 

 genus is represented in the Rocky Mountain region by this and 

 the two following species. 



Miltitzia salina (A. Nels.) Rydb. 

 Emmenanthe salina A. Nels. Bull. Torrey Club 25: 381. 1898. 



Miltitzia scopulina (A. Nels.) Rydb. 

 Emmenanthe scopulina A. Nels. Bull. Torrey Club 25: 380. 1898. 



Phacelia orbicularis Rydb. sp. nov. 



Biennial or annual; stems 1-2 dm. high, glandular-villous, 

 often tinged with red, branched; leaves petioled; blades subor- 

 bicular in outline, crenately lobed, i».5-2.5 cm. long, hirsute as 

 well as glandular; racemes many-flowered; calyx-lobes oblong 

 or oblanceolate, obtuse, 3 mm. long; corolla purplish, 6 mm. 

 long, campanulate-funnelform; lobes crenulate; filaments about 

 twice as long as the corolla; seeds faveolate, crenately lobed 

 on the margins and the median ridge. 



This is related to P. integrifolia, but the plant is smaller and 

 the leaf-blades shorter and broader. 



Utah: Marvin Laccelite, 1894, M. E. Jones 5663 (type, in 

 U. S. Nat. Herb.). 



Phacelia crenidata Torr., P. hicolor Torr., P. affinis A. Gray, 

 P. glechomaefolia A. Gray, P. hispida A. Gray, P. humilis T. & G., 

 P. demissa A. Gray, P. Palmeri Torr. (not P. Palmeri Vasey & 

 Rose), P. pinetorum Jones, and P. pusilla Torr. have been collected 

 in Utah; P. glandulifera Piper and P. ramosissima Dough, in 

 Idaho. I cannot distinguish P. luleopurpurea A. Nels. from P. 

 glandulifera Piper. Capnorea incana Greene, C. nana (Lindl.) 

 Raf., C. nervosa Greene, and C. Watsoniana Greene have been col- 

 lected in Idaho; the first one also in Montana and the last one in 

 Wyoming; Emmenanthe penduliflora Benth. and Eriodictyon 

 angustifolium Nutt. in Utah. 



BORAGINACEAE 

 Gruvelia setosa (A. Gray) Rydb. 

 Pectocarya setosa A. Gray, Proc. Am. Acad. 12: 81. 1877. 



I think that the genus Gruvelia A. DC. should be restored, 

 being quite distinct from Pectocarya. The only other species is 

 G. pusilla A. DC, the type of the genus.
