PTERIDOPHYTES OF NORTHWESTERN ONTARIO 49 
22, EQUISETUM HIEMALE var. INTERMEDIUM A, A, 
Eaton. This North American variety of E. hiemale, 
ranging from Connecticut to Michigan, Texas and Cali- 
fornia, occurs in our collections from: Open upper 
beach, Orient Bay, Lake Nipigon; shore of little lake in 
sand-plain, Jellicoe. So far as known this is a consider- 
able extension of range to the northwest. 
23. EquiseruM VARIEGATUM Schleich. Reported for 
“Sands, Lake Nepigon.”—Macoun. Our collections 
are best referred to the following variety: 
23a. EQuIsSETUM VARIEGATUM var. Jesupr A. A. 
Eaton. The reported general range of this variety is: 
Quebee and Ontario, south to Connecticut and Illinois 
(Gray’s Manual). It was found by us on a sandy 
beach, Pelican Lake, Sioux Lookout, and at Sandy 
Point, Orient Bay, Lake Nipigon. The specimens 
from the latter place were reported in the earlier list as 
E. hyemale L., but further study has convinced the 
writer that they are E. variegatum, var. Jesupi. (See 
A. A. Eaton, Fern Bull. 12: 23-25. 1904.) Under 
ramosissimum Macoun reports an Hquisetum from 
peke’s Point, southeastern Lake Nipigon, which from 
his notes ig probably to be referred to Jesupt. The 
variety Jesupi is evidently a hybrid between £. varie- 
gatum and E. hiemale (Ruth Holden. The Anatomy wt 
4 Hybrid Equisetum. Am. Journ. Bot. 2: 225-237. 
Pls. V-VIII. May, 1915.) | 
23b. Equiserum yarrecatum var. Jesupr forma 
MULTIRAMEUM Blake. Specimens with slender upper 
branches and thus referable to Blake’s form. were gTOW- 
Mg with the var. J esupi at Sioux Lookout. _ 
24. Equisetum scrrporpEs Michaux. Ranging from 
Pennsylvania and Illinois northwards to Labrador and 
British Columbia, this species is reported by Macoun 
48 Very common throughout northern Ontario, and ee
