1915]  Pease,— Arenaria stricta in the White Mountains 233 
Bartlett, Carroll County. A more extended visit on 9 September 
of the same year disclosed the plant on similar damp rocks on the 
west; slope and also in the coarse gravels of the summit (2009 feet), 
both places being a little west of the county line in Hadley’s Grant, 
Coós County. At the present, then, we may probably regard this 
ledge as the northeastern limit of the species. Near A. stricta in the 
Carroll County station was its congener, A.. groenlandica (Retz.) 
Spreng., which is not uncommon on the mountains of the Montalban 
Range, but which is perhaps seldom found in so incongruous a situa- 
tion as here, growing under the shade of red oak trees! Other species 
of interest noted upon the ledge were Panicum latifolium L., Oryzopsis 
racemosa (Sm.) Ricker, Polygonum scandens L., P. Douglasii Greene 
(in great abundance on both dry and damp ground, in the sun and in 
the shade), a slender native Chenopodium matching the description 
of C. leptophyllum Nutt., var. oblongifolium Wats., Cardamine parvi- 
flora L., Geranium Robertianum L., G. Bicknellii Britton, Arctostaphy- 
los Uva-ursi (L.) Spreng., and Specularia perfoliata (L.) A. DC. Of 
these the two Polygonums, the Chenopodium, and the Arctostaphylos 
are new to Coós County, while the Panicum, the Cardamine, and the 
Specularia are unreported from that county but on Hart’s Ledge 
miss inclusion within its limits by only a few hundred feet. Speci- 
mens of all the plants mentioned are to be deposited in the herbarium 
of the New England Botanical Club. It may be remarked that the 
vicinity of Bartlett, where plants of the warmer district of east central 
New Hampshire mingle with those of the colder areas of Crawford 
Notch and the Montalban and Rocky Branch Ranges, and where 
the numerous lower mountains are diversified by frequent cliffs 
and extensive open ledges, offers many attractions to the collector.—

TBE OCCURRENCE OF BOTRYCHIUM VIRGINIANUM, var. EUROPAEUM 
IN AMERICA.— About the Gulf of St. Lawrence, especially on the 
west coast of Newfoundland, the south coast of the Labrador Penin- 
sula, and on the Gaspé Peninsula of Quebec, there occurs a grape-fern 
clearly related to Botrychium virginianum (L.) Sw., but differing in the 
much less dissected segments of the sterile frond and, in its most 
characteristic development, in its heavy or firm texture. The plant 
proves to be a very close match for the European material passing
