1900] Averill, — Trees in western Connecticut 37 
The Greenwich station, for Ziguidambar Styraciflua, described by ` 
Mr. Harger in the July Ruopora, is not the most easterly and northerly 
station. As given in Bishop's additional list of Connecticut plants, it 
occurs from Darien to Five Mile River, where reported by Miss A. E. 
Carpenter. I visited the place last September, and made a hurried 
examination. The trees were growing plentifully in a piece of wet 
woods bounded north by the railroad track, and south by the highway 
on which the trolley runs. Easterly they extend nearly to the Five 
Mile River. I did not go to their western boundary, but they appeared 
to extend westerly for at least half a mile. This station is about eight 
to ten miles easterly from the Greenwich one. Some of the trees were 
of good size. I measured one six and a half feet round at five feet 
from the ground. There were many others that looked as large. 
While this tree has been cultivated somewhat in this region, I should 
judge this to be a natural station. 
Fraxinus sambucifolia, the black ash, which is not given in the Ber- 
zelius list, and in Bishop's list is given as rare, I have seen at a number 
of places from Stratford on the coast, to Stockbridge, Mass., always in 
wet places, but not usually near the river. 
I have mentioned the canoe birch and tamarack as showing the 
effect of altitude and latitude in their distribution. This is better shown 
in a number of shrubs which are common in the northern part ; rare or 
lacking in the southern. 
Acer spicatum and Acer Pennsylvanicum are tolerably common in 
New Milford, Kent, and in Cornwall, but not south. The Berzelius list 
gives them as occurring at stations twenty to thirty miles north of New 
Haven, except spicatum, which has a station as far south as North 
Branford. 
Viburnum cassinoides I have seen in a few elevated places in New 
Milford and Kent; V. Opu/us in several places from Kent north, also 
in Brookfield ; V. /anzanoitdes I have from one station in Kent. None 
of these have I seen in the southern portion, and they are not in the 
Berzelius list. 
Sambucus racemosa occurs among the higher hills of New Milford ; 
and while not seen in the southern part of the Housatonic region, I 
have found it at East Rock, New Haven. Cornus Canadensis is not 
rare in swamps about New Milford; it grows also in the swamp with 
the spruce trees at Botsford. It was formerly found near New Haven. 
Potentilla fruticosa is abundant over the northern half of the
