90 PITTONIA. 
linear-oblong and sessile, all obtuse, glabrous beneath, rather 
strongly strigose-pubescent above: flowers in numerous 
short-peduncled cymes axillary to all the upper leaves, or 
sometimes more exclusively subterminal: calyx parted to 
the base, its lanceolate segments marginally almost crinite- 
hirsute, the pedicels and back of the calyx strigulose: corolla 
about 4 lines long, light-blue, the tube surpassing the calyx, 
but not longer than the rather ample campanulate limb. 
A subalpine apparently dry-land species, obtained on Bob ` 
Creek, Colorado, at about 10,500 feet, by Baker, Earle and 
Tracy, 28 June, 1898, being n. 206 of their collection and 
distributed by mistake for M. oblongifolia. Also in Mr. 
Baker’s collection of 1899, from Graham’s Park, Rio de los 
Pinos, at 7,800 ft., said to be frequent in fields, and openings 
in pine woods; this plant smaller, and the leaves more 
strongly pubescent above. 
M. BRACHYLOBA. Tufted stems a foot high or more, gla- 
brous, glaucous, leafy throughout but the lower leaves much 
reduced and narrowly oblong, those of the middle portion 
oblong, the upper ovate-oblong, all sessile, somewhat cus- 
pidately or mucronately acute, glabrous or slightly papillose- 
scabrous: flowers in a short leafy panicle, the peduncles 
apparently erect: calyx turbinate, its broad setulose-ciliate 
lobes only half the length of the tube, most of them broadly 
ovate and acutish: corolla barely a half-inch long, light- 
blue, the cylindric tube rather shorter than the broadly 
funnelform limb. 
Foothills of the mountains of northern Colorado, near 
Fort Collins, 24 May, 1896, C. F. Baker, and not otherwise 
known to me; but the species is uncommonly well marked. 
It was distributed by Mr. Baker for a form of M. lanceolata, 
to which species it is not especially related. 
M. BAKERI. Stems low, less than a foot high, tufted on 
a branching caudex from a branching root, simple and leafy
