Glabrous throughout except the ciliate margins of the leaves and 
calyx lobes; stems weak, erect or nearly so, 50 to 60 cm high; basal 
and lower cauline leaves oblanceolate, obtuse, the blades 5 to 7 em long, 
shorter than the margined petioles; middle and upper cauline leaves 
lanceolate, acute or acutish, 5 to 10 em long, narrowed toward the base, 
sessile or short-petioled; inflorescence rather open, the bracts foliaceous; 
petioles slender, papillate near the calyx; calyx divided nearly to the base, 
the lance-oblong lobes smooth excepting the appressed-ciliate margin, about 
one-third as long as the corolla-tube ; corolla bright blue, about 18 mm 
long, the ampliate limb distinctly shorter than the tube; filaments dilated, 
longer than the anthers; fruit not seen.

This species is allied to M. intermedia Rydberg, but is at once 
distinguished by the larger corolla with relatively longer tube. The type 
is in the U. S. National Herbarium (sheet no. 366 088).

or somewhat papillate above, glabrous beneath, ciliate on the margin, 
5 to 7 cm long, short-petioled ; inflorescence loose, the pedicels appressed- 
pubescent or muriculate; ‘calyx divided nearly to the base, its lobes 
lance-oblong, acute, ciliate, smooth on the back, over half as long as 
the corolla tube; corolla blue, 14 mm long, the somewhat ampliate limb 
as long as the tube; filaments dilated, shorter than the anthers; nutlets 
finely muriculate, pale, the scar of attacnment central.
