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

 margins; corolla-tube 6-2 mm. long; limb 8-10 mm. long, 7-8 

 mm. wide.

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 hmb o^ the corolla. It is a larger plant than any of the 

 three and often reaches a height of i m.

M5rtensia 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-^ 

 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 alpijia by the collectors. A few "years ago the present 

 writer regarded them as representing the typical M. alpiita and 

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

 obtiisiloba. A reexamination of James's plant (type o{ M. alpina) 

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

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

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

 intermediate between the two.
