60 Aug. 25 (Monday) The summit of Buck Mt. (2380 ft.) has great areas of bare surface, covered mainly by Potentilla tridentata with scattered plants of Prenanthus trifoliolata (?) and Aster undulatus. On sheltered northern slopes, Cornus canadensis, Lysimachia borealis and Aster acuminatus. Further down on the exposed slopes (1800 ft.) Rosa acicularis var. Bourgmarie, Oryzopsis junceus. Sept. 2. (Wednesday) Quebec. Bidens hypoborea collected on St. Laurence north side at Anticosti, number dock 1 or 2 miles below Quebec and 2 at Montremery and 3 on rocky estuary, south side of Isle of Orleans. Four general variations of the species are encountered but they do not here seem to represent more than response to varied conditions and to overcrowding. a) The tall branchy plant, common in flooded meadows and frequently representing the great mass of material of the species. It is usually stouter, growing 1-2 ft. tall, with pale rather in compressed rays. Also when the plants are growing in masses, and generally mixed with Bison cicutifolium, juncea nodosa, Elecharis calva, Eupatorium perfoliatum, Zigadenus palustris var. brevis. b) A plant with spreading bird branches, found chiefly around marshy pools, in quiet backwaters (i.e. at Montremery). c) Decumbent plants on hard gravel and rocky beaches. These occur as solitary plants.
