1901] Robinson, — North American Euphrasias 273 
the middle somewhat larger, ovate, the floral obovate to flabelliform 
or suborbicular, closely approximated in a dense head; teeth 7 to 
9, short, triangular, acutish, the terminal tooth of each floral leaf 
broader and more obtuse but mucronulate; the sinuses acute or at 
least not conspicuously rounded: flowers very small, confined to the 
terminal subglobose head and one or two of the upper axils just 
beneath it: calyx 4 mm. long, the teeth lanceolate, ciliolate with very 
short and inconspicuous hairs and terminating in a narrow somewhat 
uncinate point: corolla brownish purple, 3.5 to 4 mm. long dorsally, 
its pubescence minute and visible only with a strong lens; lips about 
equal in length, the lower paler in color and internally marked by 
a small yellow eye: capsule elliptical, ciliate toward the obcordate 
summit, otherwise glabrous.— Eastern slopes of Mt. Washington, 
New Hampshire, alpine region, stony ground and crevices of rock 
on the “Alpine Garden” at the head of Raymond’s Ravine and of 
Huntington Ravine, 5 Aug. 1901, Æ. F. Williams & B. L. Robinson 
(type); ledges near the 5th mile post on the spur known as “ Cape 
Horn," 6 Aug. 1896, Æ. Faxon & E. F. Williams; at the same 
locality 6 Aug. 1901, Æ. F. Williams & B. L. Robinson. 
This species possesses a close habital similarity to the preceding 
and in the dried state might easily be confused with it, unless the 
very different pubescence were noticed. In a fresh state, however, 
the deep brownish purple corolla and greener foliage readily distin- 
guish it from Æ. Oakesti, There are also minor differences in the sinu- 
ses between the teeth of the leaves, smoother less uncinate calyx- 
teeth, etc. Mr. Williams and the author examined about six hundred 
individuals of this species and more than a thousand of E. Oakesz, 
but could detect no intermediates. 
* * Flowers very small (corolla 3 to 4 mm. long), borne in long open 
racemes; stems simple or few-branched: leaves small, bluntly toothed, 
pubescent on the veins beneath. 
E. Randii. Simple or few-branched from near the base or 
(rarely) much branched throughout, erect or decumbent, 3 to 12 cm. 
high; stem purple, covered with very short recurved white hairs and 
bearing ro to 13 pairs of leaves (separated by short internodes of 
nearly uniform length) and a small terminal dense leafy head: 
leaves suborbicular, 9—11-toothed, the larger 7 to 9 mm. long, 
broadly subcordate, finely subappressed. pubescent upon the dark 
green rugose upper surface, setulose upon the prominent veins of the 
paler lower surface, the teeth obtuse or barely acute,, not aristate, all 
pairs of leaves, except one or two of the lowest floriferous in one or 
both axils: flowers small, subsessile: calyx pubescent, 3.5 mm. long ; 
the teeth triangular, lanceolate, flattish and nearly or quite straight, 
finely pubescent upon both surfaces: corolla cream-colored with red- 
dish veins to deep purple or violet, marked with still deeper veins, 
greenish toward the base, nearly glabrous; lips short, about equal :
