Association. — The third belt is confined to the summit and a small portion 
of the slopes being covered with a low dwarf growth of shrubs Zedum lati- 
Fohum, Cassandra (Chamaedaphne) calyculata, Vaccinium uliginosum, (Alpine 
Shrub-Formation.) 
The great table-land and canyon walls of Mt. Albert in Gaspe: New Bruns- 
wick although exposing many square miles of alpine region, have a compara- 
tively sparse flora: but the few species which abound there are of the greatest 
interest to the botanist, for, with but few exceptions, they are quite unknown 
upon any other mountains, or cliffs in eastern North America. 
The plants which are strietly localized), in the rock crevices and on the talus slopes of Mt. Albert 
ake up, so far as yet determined a flora of only 21 species (8.15 per cent of the 258 alpine and sub- 
alpine plants), but this flora includes the distinetive Adiantum pedatum var. aleuticum, Cryptogramme 
densa, Polystichum scopulinum, Deschampsia caespitosa var. alpina, Danthonia intermedia, Festuca 
altaica, Salix desertorum, S. chlorolepis, Lychnis (Viscaria) alpina, Arenaria ciliata var. humifusa, 
. sajonensis, A. arctica, Statice sibirica, Solidago decumbens, Artemisia borealis, and var. Worms- 
kioldii, Cirsium (Carduus) muticum var. monticolum. — The northern crests and slopes of Mt. Albert 
have in addition to common alpine plants the following noteworthy species: Carex lagopina, Luzula 
spicata var. tenella, Sagina Linnaei (Spergula saginoides L.), Ranunculus pygmaeus and R. Allenii. 
2. The Hygro- and Halophytic Formations. 
Rier Bank Formation. The following shrubs are to be found along the 
shores of the rivers: 
Salix humilis, S. rostrata, S. discolor, Sambucus canadensis, Viburnum opulus, V. nudum, 
Sorbus americana, Corylus rostrata, Diervilla trifida, Prunus virginiana, Myrica gale, Nemopantbes 
faseicularis, Cephalanthus oceidentalis, Ribes prostratum and associated with these is an herbaceous 
element also occurring on lake shores. 
The banks of the Nepisiguit River are characterized by thickets of Viburnum opulus, V. 
pauciflorum, V, cassinoides, Nemopanthes, clumps of Osmunda regalis and ostrich fern, Onoclea 
struthiopteris?). The Sisson Branch of the Tobique River in New Brunswick narrows to a gorge 
through which the river runs in a series of rapids and cataracts. The gorge consists of perpen- 
dieular rocks on which grow Asplenium viride, Arnica mollis, Woodsia ilvensis, W. hyperborea 
=W. alpina), W, glabella, Aspidium fragrans, and Erigeron hyssopifolius (= Aster graminifolius). 
Siream — (and Lake) — Bank Plant Formation. This occupies the 
Situations between the forest formation and those of the water, where the 
air conditions are mesophytic, but the roots conditions are hydrophytic. 
Potentilla anserina, Ranunculus (Oxygraphis) Cymbalaria grow on sandy 
ground at the mouth of streams. The alder, Alnus incana, is the dominant 
member of this very characteristic association often forming extensive alder 
Swamps and also sometimes in drier places under xerophytic conditions. 
A distinct band of vegetation on the shores of the smaller northern lakes 
along the forest edge consists of Myrica gale and Rhododendron Rhodora 
(= Rhodora canadensis) and forms the Myrica-Rhodora association.
