FERNS OF GLACIER PARK 101 
than that reported here for Glacier Park. The species 
listed from Montana but not found by the writer in the 
Park are Botrychiuwm Coulteri, Asplenium Trichomanes, 
Pellaea glabella, Marsilea vestita, Equisetum scirpoides, 
and Isoetes Bolanderi. Of these, the Botrychium, Asplen- 
ium, and Equisetum were collected by R. 8. Williams at 
Columbia Falls, only a few miles from Belton, and they 
are almost certainly to be found in the Park. 
OPHIOGLOSSACEAE 
Botrychium virginianum europaeum Angstr. Found 
chiefly at middle altitudes. The plants are usually scat- 
tered and many of them are sterile. The first ones seen 
by the writer were found by Miss Gertrude Norton in 
woods about Lake McDermott. Scattered plants were 
collected later on mossy banks in swampy woods below 
the lake. In an open bog ona slope along the road near 
Many Glacier Hotel there must have been hundreds of 
them, of all sizes. They grew in deep moss under scrub 
birches and willows, with Habenaria dilatata and Par- 
nassia fimbriata. On the west slope the plants are often 
larger than on the east slope. Here they are found in 
swampy thickets in deep woods. Individuals growing 
in the open were yellowish green, while those in the 
woods were deep green. 
Botrychium silaifolium Presl. Rare; @ few small 
plants in sphagnum bog at Johns Lake; larger ones along 
Swiftcurrent Creek below Lake McDermott, in a wet 
thicket near beaver runs, under willows and Rhamnus 
alnifolia. 
Botrychium Lunaria L. Rare; seen only on the east 
slope; a few isolated plants.found on grassy slopes, in 
bogs, and on mossy banks in deep woods. Coliected by 
Williams at St. Mary Lake. The only locality at which 
the species was found in abundance was on the moraine 
at Grinnell Glacier, where there were dozens or hundreds
