PLANT NOTES FROM TADOUSAC 253 



found. The bottom was in some places gravelly and in others of sandy- 

 clay. The water was beautifully clear, but two or three feet in depth. 

 We found here five Potamogetons : P. pectinatus, P. gramineus, P. 

 amplifolius, P. natans, and P. perfoliatus, the delicate Ranunculus 

 aquatilis, var. irichophyllos, and two species of Chara. Here and there 

 the spikes of the great bulrush, Scirpus lacustris, rose six or seven feet 

 above the surface of the water. 



Most beautiful of all were the Myriophyllums; one of these, ver- 

 ticillatum, grew near our camping place in great masses, and we could 

 look down into the clear water and trace the long, feathery, unbranched 

 stems until they reached the sand, some seven or eight feet below. 



Another species, more slender and growing in much shallower 

 water, we have since determined as Myriophyllum alterniflorum. 

 Attention has been called to this interesting species by Dr. Morong in 

 a previous number of the Bulletin (xiv. 51), where he states that it 

 has been found in Lake Memphremagog, Canada, by Mr. J. R. 

 Churchill, but previously had been collected no nearer to us than 

 Greenland. 



Well pleased with our morning's spoils, we paddled on a mile or 

 so farther, until we found a good camping place, when we dis- 

 embarked and soon started for the top of la grosse montagne. 



Our trail led up through the usual growth of balsam, white spruce, 

 and Betula papyrifera; here and there the ledges were luxuriously 

 carpeted with Cladonia rangeriferina. Higher up we found dozens of 

 specimens of Habenaria Hookeriana, and even more abundant was 

 Corallorhiza multiflora. We also found some few spikes of C. innata. 

 About 550 feet above the lake we found some plants of Epigaa repens 

 (the first we had seen in Canada) surrounded by Vaccinium Pennsyl- 

 vanicum, Kalmia angustifolia, and Ledum latifolium, and shaded by 

 black and white spruces. Among the crannies of the upper ledges we 

 found Woodsia Ilvensis, W. hyperborea, Pellaa gracilis, and Aspidium 

 fragrans. 



The summit was shaded by very fine specimens of the red pine, 

 Pinus resinosa. The next day we worked up our plants, collected 

 some fossils from the ledges at the foot of the mountain, and later on 

 in the afternoon started back for Notre Dame du Lac. The few 

 remaining days we spent there were devoted to grasses and sedges — 

 there was not a very great variety of either, however, and their names 

 will be found in the appended list.
