This has been confounded with the preceding, but differs in the 

 very short rounded calyx-lobes, those of M. Sibirica being linear- 

 oblong. Along streams, up to an altitude of 2500 m.

* Mertensia intermedia. 



Perennial, with a short erect rootstock ; stem 3-4 dm. high, 

 glabrous, slightly striate, strict and simple ; lower leaves oblanceolate, 

 obtuse, about i dm. long, the blade tapering into a winged petiole, 

 minutely scabrous and with scabrous-ciliate margin ; upper leaves 

 oblong or lanceolate, subsessile ; panicle with few branches ; calyx 

 divided three-fourths its length, 3-4 mm. long, enlarging in fruit, 

 often 8 mm. long, hispid-ciliate ; corolla-tube 8-10 mm. long, three 

 to four times as long as the calyx, and longer than the limb, which 

 is 5-8 mm. long and 8-10 mm. wide; nutlets about 3 mm. high, al- 

 veolar and white-spotted. 



In the size and form of the corolla it stands nearest to M. Sibirica 

 and M. fanicidata; it has the sepals of the latter. The leaves, 

 however, are different ; they are not ovate as in those species, but ob- 

 lanceolate or lanceolate as in M. lanceolata and M. Driimmondii, 

 from which it differs in the taller habit and much longer corolla- 

 tube. Grows in rich soil, on hillsides, at an altitude of 2000 m.
