WEST AMERICAN ASPERIFOLIZ. 89 
ness: corolla little more than 1 inch long, decidedly broad, 
the tube shorter than the limb. 
Known only from along the Tananah river, Alaska, 
where it was obtained by Mr. Octavius S. Bates in 1881. 
The stream so named is, I believe, one of the tributaries of 
the Yukon. 
M. PLATYPHYLLA, Heller, Bull. Torr. Club, xxvi, 548, is 
certainly of this group; and all three here associated are 
plants having a far closer likeness to the genus Pulmonaria 
than other and more typical Mertensia species exhibit. 
M. suBCORDATA. Stems two feet high, slender and slightly 
flexuous, leafy up to the loosely panicled inflorescence; basal 
leaves not seen, those of the stem ample, very thin, ovate, 
very acute, rounded or subcordate at base, all distinctly 
petiolate, the petioles sparsely hirsute-ciliate, this pubes- 
. cence extending to the whole lower face of the leaf, the 
upper surface sparsely muricate-scabrous: flowers few, in 
loose panicled terminal cymes, their slender pedicels 
and also the oblong-lanceolate divisions of the calyx 
strigose-pubescent: corolla about 8 lines long, the cylindric 
tube rather wide, shorter than narrow-campanulate limb. 
Species known only as collected by Mr. Howell, in the 
Umpqua Valley at Roseburg, Oregon, 3 May, 1887, and very 
distinct by many characters; the texture, outline, pubes- 
cence and remarkable petioles of the leaves all being pecu- 
liar; and the herbage seems to be not at all glaucous. 
The three following species, proposed as new, belong to 
the group of more strict and simple-stemmed small upland 
comparatively xerophilous plants. 
M. rusiFORMIS. Stem erect, six inches to a foot high, 
usually solitary (occasionally two or three together) from a 
large oblong or fusiform root, simple and leafy to the sum- 
mit: lowest leaves spatulate-oblong, long-petioled, the others
