Rydberg : Rocky Mountain flora 681 



late, 4 mm. long, twice as long as the calyx-tube, ciliolate on the 

 margins; corolla-tube 6-7 mm. long; limb 8-10 mm. long, 7-8 

 mm. wide. 



This is related to Merteiisia ai'izonica, M. intermedia, and M. 

 stenoloha. From the former it differs in the long calyx-lobes and 

 the short calyx-tube and from the latter two in the long and 

 ample limb of the corolla. It is a larger plant than any of the 

 three and often reaches a height of i m.

Mertensia humilis sp. no v. 



Perennial, with a woody tap-root and cespitose caudex ; stem 

 1—2 dm. high, ascending or decumbent, glabrous ; basal leaves 

 petioled, 3—8 cm. long ; blades thick, elliptic to ovate, glabrous 

 beneath, pustulate-muricate above, ciliolate on the margins, stem- 

 leaves sessile, elliptic or ovate, rarely oblong, 2—4 cm. long ; 

 pedicels with scattered large pustules ; calyx-lobes lanceolate, 2-3 

 mm. long, hispid-ciliolate on the margins ; corolla 7-8 mm. long; 

 tube slightly shorter than the limb ; stamens inserted in the tube 

 of the corolla ; filaments short and narrow. 



The specimens referred to this species w^ere all named Mer- 

 tensia alpina by the collectors. A few years ago the present 

 writer regarded them as representing the typical M. alpina and 

 redescribed the true M. alpina (Torr.) Don under the name M. 

 obtiisiloba. A reexamination of James's plant (type of M. alpina^ 

 has convinced me of the identity of M. alpina and M. obtusiloba. 

 M. humilis combines the corolla and stamens of M. alpina with the 

 leaf-surface, pedicels, and calyx of M. lanccolata. In habit it is 

 intermediate between the two.

 puberulent, more or less purplish ; leaves below the inflorescence 

 ovate, obtuse, coarsely crenate, 1—4 cm. long, minutely puberulent 

 or glabrate, short-petioled ; those of the inflorescence and branches 

 oblong and entire or nearly so ; pedicels 3—5 mm. long ; calyx
