194 Rhodora [OCTOBER 
1868, H. Gillman. Kerwatin: Churchill, lat. 58° 50’, July 29 and 
August 3, 1910, J. M. Macoun, Herb. Geol. Surv. Can., nos. 79,380, 
79,381. ; 
Intermediate between E. disjuncta and E. stricta, var. tatarica. 
Extremes are difficult to distinguish from those plants. From the 
former E. arctica differs in the shorter internodes, denser inflorescence 
with more ascending bracts, more acute bracteal teeth, and slightly 
larger corolla. From the latter it may be distinguished by the less 
subulate bracteal teeth and smaller corolla with paler lines and with 
less spreading lobes of the lower lip. 
Wettstein took up for this boreal species the name Æ. latifolia 
Pursh, not L. (or, as Pursh said, Willdenow), because the Linnean 
(and Willdenowian) Æ. latifolia does not belong to the genus Euphrasia 
as now interpreted and because the Labrador plant seen by Pursh 
was a true Euphrasia (the plant here treated as E. arctica). It is 
clear, however, from Pursh's treatment that he had no intention of 
publishing a new species but merely copied literally from Willdenow 
the description of the Linnean Æ. latifolia of the Mediterranean 
region, a plant belonging in the genus Parentucellia.

centibus simplicibus vel inferne sparse ramosis, ramis longis valde 
adscendentibus, internodiis inferioribus 1.5-4 em. longis; foliis 
oblongis 15 mm. longis sparse pubescentibus, dentibus paucis acutis; 
spicis longis, eis primariis in maturitate 0.5-1.5 dm. longis, inter- 
nodiis inferioribus 1-3 em. longis; bracteis 5-15-jugis grandis oblongis

labio superiore purpureo-tincto bilobato, lobis semireflexis; labii in- 
feriori lobis vix divergentibus. 
Plant 5-22 em. high; stem pubescent, simple or sparingly branched 
below; branches long, strongly ascending; lower internodes 1.5-4 cm. 
long: leaves oblong, 15 mm. long in the larger plants, sparingly 
pubescent, with a few very coarse acute teeth: spikes rather long; 
the primary ones in maturity 0.5-1.5 dm. long, with the lowest inter- 
nodes 1-3 em. apart: bracts 5-15 pairs, large, oblong, 7-15 mm. long, 
ascending, coarsely and very sharply aristate-toothed: corolla 5.5- 
6 mm. long, whitish with pale violet lines; upper lip suffused with
