regions, occurring on Mt. Katahdin, the Bigelow Range, and Sar- 

 gent Mt. on Mt. Desert Island in Maine, the White Mountain region 

 and Mt. Monadnock in New Hampshire, Mt. Mansfield in Vermont 

 and Mt. Greylock in Massachusetts. But it occurs also at lower alti- 

 tudes at East Dover, N. H., and Johnson, Vt., has a station at Mt. 

 Holyokc in Massachusetts and descends nearly to sea level at Deer 

 Isle, Me., and on trap ridges near New Haven, Conn. The other 

 species and varieties are all, apparently, rather rare, occurring at com- 

 paratively few and scattered stations in the three northern states. 

 Only Lycopodium mnotinum, var. pungent reaches the vicinity of the 

 sea, at Lubec, Cutler and Wass Island on the cold eastern coast of 

 Maine: only L. complanatum and L. sabinaefolium, which are both 

 found at Hartland, Vt., extend further south than the White Moun- 

 tain region. 



V. Cape Cod and ratheh general elsewhere, hit not the 

 upper St. John. 



Botrychiuin angustisegmentum Botrychium dissectum, 



f. obliquum 

 Botrychium dissectum Ophioglossum vulgatum 10 



Lycopodium inundation 



This group corresponds essentially to the Southern A of the last 

 report. Botrychium angustisegmentum and B. dissectum, like their 

 congeners in group III, have outlying stations at Bridgewater, in the 

 deciduous woods region of northeastern Maine. The former is not 

 known from the Maine coast east of Boothbay. The four Ophio- 

 glossaceae are all plants of comparatively southern range, Inning 

 their northeastern limits in New England or the Maritime Provinces. 

 Li/rojtodinni inundatum, on the other hand, is of wide distribution in 

 northern latitudes in America and Eurasia, reaching, in the eastern 

 United States, no further south than Pennsylvania. In any analysis 

 of the geographic elements of the New England flora ba ed on gen- 

 eral ranges it would have to be placed in a different group from the 

 other species here included; but within New England its occurrences 

 correspond in general with theirs, except for two stations on the 



'" Including var. nanus, which appears to he only a starved and depauperate state 

 growing in sand. See Stone, Plants of Southern N. J. 122 (1911).
