1919] Knowlton,— Excursion to Mt. Washington 199 
plateau by a sinuous and difficult road, with occasional glimpses of 
white birches and Rhododendron canescens, the latter in full bloom. 
In this high region we made our first collections — Castanea dentata, 
Corylus rostrata, Quercus alba, Q. ilicifolia, Amelanchier canadensis, 
Prunus virginiana, P. serotina, P. pennsylvanica, Vaccinium vacillans, 
V. canadense, Kalmia latifolia, Lyonia higustrina, Diervilla Lonicera, 
Smilax herbacea, Clintonia borealis, Geum rivale, Polygala paucifolia, 
Pedicularis canadensis, and Senecio aureus, with other familjar plants, 
not very different from those seen in similar acid areas in the 
Fitchburg plateau region. 
The next halt was by a school-house. Happy children, with woods 
and fields and a real brook to play in! In the brook grew Stellaria 
borealis Bigel., var. isophylla Fernald and Geum virginianum, with 
Zizia aurea close by, while in the light woods were Uvularia perfoliata 
and the inevitable Aralia nudicaulis. Around an old house-site were 
several introduced plants of which Levisticum officinale may deserve 
the honor of a record, along with an apparently transplanted native, 
Viburnum Opulus, var. americanum. 
We now coasted rapidly into the Vale of Bash-Bish. Here were the 
rich woods we expected, with Tsuga canadensis, Betula lutea and B. 
lenta, Fagus grandifolia, Ulmus fulva, Tilia americana and Acer sac- 
charum, together with the following shrubs: Taxus canadensis, 
Hamamelis virginiana, Dirca palustris, Ribes Cynosbati, Acer pennsyl- 
vanicum, Lonicera canadensis, Viburnum alnifolium and Sambucus 
racemosa. 
There were dry woods, too, mainly oak with some chestnut and a 
few white pines. In the rocky woods above the falls Quercus Prinus 
was very abundant, with some specimens of Fraxinus americana. 
In this region were brilliant flowering clumps of Silene pennsylvanica 
in the driest places. Quercus alba and Q. rubra were further down the 
gorge. With these trees grew Myrica asplenifolia, Rubus alleghenien- 
sis, Ceanothus americanus, Rhus typhina, Cornus florida, Vaccinium 
stamineum and Viburnum acerifolium. 
The greatest surprise of the day was the striking contrast between 
the northern sunny side of the gorge, and the shaded southern side.— 
To find Oxalis americana and Acer spicatum on one hand, and then only 
a few yards away Gerardia virginiana and Scirpus planifolius was 
indeed strange. The following lists of herbaceous plants emphasize 
the contrast further.
