in g the bridge, Catoscopium nigritum, growing among the grass. Near the 
stream referred to above, south of the observatory trail, Encalypta rhabdocarpa 
and Tor tula mucronifolia grow on the wet earth of the stream bank. 
Most of the above species with the addition of Hygrohypnum alpestre grow 
also along the Spray River to the south. In fact, all around the base of Sulfur 
Mountain in the Sundance, Bow, and Spray Valleys there are many, many mosses, 
of which those mentioned above represent only “pickings” from limited collec- 
tions. Hepatics are very abundant, especially those of the Lophozia group: 
LL. badensis, barbata, excisa, grandiretis, heterocolpa, Hornschuchiana, incisa, 
Kaurini, longiflora , Muelleri, Schultzii , and ventricosa, have been gathered here, 
nearly always on wet or damp earth, besides Sphenolobus exsectaeformis , 
Michauxii, politus, and scitulus. Calypogeia sphagnicola associated with Ric- 
cardia major and Cephalozia pleniceps is found on the peaty stream sides, with 
Calypogeia Neesiana on decayed wood; Pallavicinia Flotowiana grows on the 
wet earth, Arnellia fennica in or beside the small streams, and Scapania Bart- 
lingii on the ledges beside them. Really it is only by considering the small 
area, some four square miles, covered rather imperfectly in this account, that it 
is possible to gain an idea of the extensive collections that may be made here. 
The altitude varies from 4500 to 7000 feet, between which limits there is the great- 
est variety of habitats: rock bluffs, cliffs, gullies, stream beds, peat bogs, river 
marshes, wet open land, forest — it is a paradise for the collector. 
For a trip up Rundle Mountain it is necessary to make an early start, and 
make certain plans beforehand. As has been mentioned, there is a practicable 
course up the stream bed between the shoulder and the main peak, but it is well 
when on Sulfur Mountain to take careful notes of the position since the trail is 
not very distinct. On leaving the stream bed, also, careful notes should be 
taken or marks made to avoid difficulty on the return. Hepatics, while not un- 
common, are less frequent upon the higher slopes than further down, and for the 
most part duplicate those already mentioned in connection with Sulfur Mountain. 
The mosses, however, furnish many new forms. Tetraplodon mnioides grows on 
dung in the lower wooded slopes, Encalypta Selwyni in rock crevices along the 
stream and E. streptocarpa on the earth, Andreaea nivalis on the wet rocks, 
Stereodon fastigiatus in the stream bed and Hygrohypnum palustre beside it, 
Orthotrichum pulchellum amid the rocks on the mountain. The summit is easy 
of access once the slope has been gained, and affords especially fine views of the 
Bow River valley, with the higher, snow-clad peaks in the distance with their 
snow fields and glaciers. 
Two other trips that promise well, but which I have been unable to take 
personally, are along Forty-mile Creek, between Stony Squaw and Norquay 
Mountains, and around Lake Minnewanka, to which daily trips are available 
from Banff with a hotel at the lake that would permit of a longer stay should 
conditions warrant. Indeed, the great point in favor of Banff as a center for a 
botanical holiday is the comparative ease with which interesting collecting 
grounds may be reached. And, let me say in passing, the flowering plants are 
as numerous and as beautiful as the bryophytes.
