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 Mertensia arizonica, M. intermedia, and M. 

 stenoloba. 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 1 m.

Mertensia humilis sp. nov. 



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 were 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 (Ton.) Don under the name M. 

 obtnsiloba. A reexamination of James's plant (type of M. alpina) 

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

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

 leaf-surface, pedicels, and calyx of M. lanceolata. 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
