rosebay, Rhododendron Lapponicum, the Lapland diapensia, Dzap- 
ensia Lapponica, the hairy fly honeysuckle, Lonicera cwrulea, and 
the dwarf birch, Betula glandulosa. The hairy fly honeysuckle 
and the small cranberry had not before been observed by me on 
the open summit of the mountain and should be added to the list 
of plants already published as belonging to that elevated station. 
July is given in the Manual and also in the State Flora as the time 
of flowering of the alpine or Lapland rosebay, but here it was 
flowering finely on the tenth day of June. Several new and 
interesting species of fungi rewarded my search in that bleak 
locality. Near the base of the mountain, the few fruited June 
berry, Amelanchier Canadensis, var. oligocarpa, enlivened the dark 
evergreen forest with its few pure white flowers. These are much 
scattered on the branches, there being only one, two or three in a 
place. The petals are broadly oval or almost erbicular, and the 
branches are wide-spreading, straggling and irregular. These 
features are so unlike the corresponding ones in other varieties of 
the species, that for the instant they almost compel us to believe 
that the plant is a distinct species rather than a mere variety. Yet, 
in less elevated and more open places connecting forms appear. 
Along Marcy brook, the rare mountain bush cranberry or tew 
flowered viburnum, Viburnum paucifiorum, was observed, but it 
was not yet in flower. At Ausable ponds the large leaved avens, 
Geum macrophyllum, was discovered. This is a notable addition 
to our flora. It is an inhabitant of the White mountain region of 
New Hampshire and of the Lake Superior region, whence it 
extends westward to the Sierra Nevada mountains, and northward 
to Sitka. This New York station is intermediate between the 
eastern one and the nearest western one. An interesting form of 
the northern Clintonia was also discovered at this time. Init, one 
or two lateral umbels project from the scape at short distances 
below the terminal umbel of flowers. I find no mention of this 
form in our botanies. It is apparently due to a very thrifty and 
vigorous condition of the plant. The number of flowers in an 
umbel often much exceeds the number ascribed in the descriptions 
of the botanies. 
From time to time reports have reached me that a red-flowered 
form of the white water-lily, Vymphwa odorata, existed in some 
of the waters of the Adirondack region. As I had never been
