the Arctic Circle, but reaching nearest to New York City in the 
Catskills. 
Canadian Blueberry ( Vaccinium ea?iadense) , a low bush not 
over eighteen inches tall, with leaves bright green on both sides, 
and nearly evergreen. 
Adoxa ( Adoxa Moschatellina), remarkable because it is found 
in New York State only near Arkville, Delaware county, on moun- 
tains that drain into the upper portion of Ashokan reservoir. 
Large-leaved Golden-rod ( Solidago macrophylla) , reaching its 
most southerly distribution point on the highest peaks of the 
Catskills, and found far northward in the Hudson Bay region. 
There are a few others of these essentially far-northern 
species that find their most southerly outposts in the higher 
elevations of the water system of Ashokan, bringing such 
species nearer to the City than anywhere else the plants occur. 
It would be a fitting permament memorial of the completion of 
the water system if the City could acquire some tract near the 
Ashokan reservoir containing these rare plants and thus pre- 
serve them. 
At somewhat lower elevations, in fact nearly throughout the 
Catskills and in the higher elevations of the Hudson Highlands, 
are many other species that are rare or wanting along the lower 
stretches of the Hudson nearer sea-level. Among the most beau- 
tiful of these are: 
Clintonia (Clinlo?iia borealis ), with yellow flowers and glossy 
basal leaves. 
Green Orchis ( Habenaria hyperborea) , with spurred, irregu- 
lar, greenish-white flow T ers. 
Showy-f ringed Orchid ( Habenaria grandiflora) , with very 
striking purple-fringed flowers in July. 
White Adders-Mouth {Microstylesmonophyllos) , a small orchid 
with whitish flowers. 
Coral-root ( Corallorkiza trifida ), a slender saprophytic or- 
chid with whitish stems and flowers, but no leaves. 
Northern Stitchwort ( Stellaria borealis), a white-flowered 
chickweed-like herb found on wet rocks and flowering in 
summer. 
Mountain Sandwort ( Arenaria groenlandica) , making small 
tufts in rocky places. Flowers white, in summer. 
Foam Flower ( Tiarella cordifolia) , with beautiful white flow- 
ers in Majr and June, so plentiful as to suggest its common name. 
Found very sparingly below Peekskill, if at all. 
Purple or White Avens ( Geum rivale), with not very numerous 
flowers, and tassel-like, silky fruits. 
Barren Strawberry ( Waldsteinia fragarioides) , a strawberry- 
like plant with white flowers, and dry fruits. Leaves nearly ever- 
green.
