Var. vestitus, var. nov., a forma typica differt lemmatibus villosi- 
hirsutis. 
Differs from the typical form in the villous-hirsute lemmas.— Ap- 
parently very common: New Brunswick (introduced) and Maine 
(introduced) to Delaware, westward to Oregon, southward in the 
Mississippi Valley to Missouri, and southwest to Arizona. ‘TYPE (in 
Herb. N. Y. State Col. Agric., Ithaca): dry ground, Cedar Point, 
Erie County, Ohio, July 17, 1914, L. H. MacDaniels, no. 106. 
The E. canadensis, forma crescendus Ramaley, Bull. Geol. & Nat. 
Hist. Survey Minn. 9, p. 114 (1894) and the EF. crescendus Wheeler, 
Minn. Bot. Stud. iii. 106 (1903) were probably based on material 
which is here included in the variety vestitus, but since they were 
based on size, not on pubescence of the lemmas, and since the name 
has not been used as a varietal name, it seems best not to take up one 
so inappropriate for our present variety. Certain specimens from 
Minnesota and the Dakotas have hairy leaves and sheaths, and may 
be the E. canadensis var. villosus Bates, Amer. Botanist, xx. 17, 
(1914). In some of the specimens from the Northwest the glumes 
are unusually narrow.

Tue region of Silurian, Cambrian and Lower Carboniferous lime- 
stones and calcareous slates and sandstones extending from northern 
Maine to the St. Lawrence and across northern New Brunswick to 
the Gaspé Peninsula and Anticosti is strongly differentiated from the 
coastwise district of southern Maine, southeastern New Brunswick, 
and Nova Scotia, where the soils are chiefly derived from acid or at 
most only slightly calcareous rocks. Hundreds of species are known 
from the St. John Valley in Maine and New Brunswick and from 
Rimouski Co., Quebec, to Gaspé and Anticosti which are quite absent 
from the acid soils to the south and southeast; and almost every 
group of plants, when critically studied, furnishes striking cases of 
this differentiation.
