Statistics of the Flora of the Northern States, 



The data are not at hand for extending this table through the 

 higher Cryptogamia, except for the highest class, and that im- 

 perfectly. The four orders of Vascular or Acrogenous Cryptoga- 

 mia give the following results ; the columns being homologous 

 with those of the last table.

These tables necessarily include the species of our small alpine 

 region, which, being chiefly Arctic, might properly be regarded 

 rather as intruded members of the Arctic flora. Being mostly 

 diffused all round the world, they increase somewhat unduly the 

 numbers of our species common to Europe and to Asia; but 

 they are not sufficiently numerous with us to require to be for- 

 mally eliminated. The following are all the Phaenogamous spe- 

 cies which, within our limits, are found only in our small alpine 

 region, namely, on the summits of the White Mountains of New 

 Hampshire, of Mount Katahdin, Maine, and the highest peaks 

 of the Green Mountains, Vermont, and the Adirondack Mountains 

 in Northern New York : — 



Cardamine hellidifolia. 

 Viola palustris. 

 Silene acaulis. 

 Sibbaldia procumbens. 

 Dry as integrifolia, (fide Pursh) 

 Potentilla frigida. 

 Epilobium alpinum, var. majus. 

 Saxifraga rivularis. 

 Gnaphalium supinum. 

 Nabalus Boottii. 

 Nabalus nanus. 

 Vaccinium crespitosum. 

 Arctostaphylos alpina. 

 Phyllodoce taxifolia. 

 Rhododendron Lapponicum. 

 Veronica alpina. 

 Diapensia Lapponica. 



Of these 33 species, two (Nabalus Boottii and Calamagrostis 

 Pickeringii) are peculiar to our own alpine region, so far as is now 

 known, but they are most likely to occur further north ; and 

 two (Nabalus nanus and Vaccinium ccespitosum) are peculiarly 

 North American. All the rest are European, and with two or 

 three exceptions also Asiatic. No one of our vascular Crypto- 

 gamous species is wholly alpine, Lycopodium Selago comes the 

 nearest to being so. 



Oxyria reniformis. 

 Betula nana. 

 Salix phylicifolia. 

 Salix Uva-Ursi. 

 Salix repens. 

 Salix herbacea. 

 Luzula arcuata. 

 Luzula spicata. 

 Juncus Irifidus. 

 Carex capitata. 

 Carex atrata. 

 Phleum alpinum. 

 Calamagrostis Pickeringii. 

 Poa laxa. 



Aira atropurpurea. . 

 Hierochloa alpina.
