1917] Additions to the Flora of Connecticut 105 
The distribution of var. polyclados is essentially that of the coast plain 
along the Atlantic seaboard and inland up the Mississippi basin with its 
most marked development along the Atlantic seaboard from Marthas 
Vineyard southward where it was segregated as A. littoralis. A study 
of the type of A. littoralis Nash and of other specimens so determined 
by Mr. Nash fails to show any satisfactory combination of characters. 
It is true that these specimens usually show a tendency to have 
several nodes close together at the base of the culm and a marked 
tendency toward a vertical rootstock, but I believe these are ecological 
characters due to the sandy soil as gradations are common and simi- 
lar tendencies were noted in var. frequens. The compression of the 
sheaths also seems too instable to carry weight and the glaucousness 
of the plant and the longer hairs at the apex of the internodes [this 
character was used by Nash to key out A. littoralis] do not couple 
with other characters. The flabellate character of the inflorescence 
seems reasonably constant and coupled with a definite geographic 
range, but intergrades with var. frequens and hence I believe is better 
considered a variety than a species. A single marked exception occurs 
linking this variety to var. villosissimus [one or two specimens of var. 
villosissimus are however noted as approaching var. polyclados]. 
New Jersey: Five-mile Beach, MacElwee, no. 2024. The following 
specimens, listed above approach var. frequens in a greater or less 
degree, but all show a noticeably flabellate tendency in the inflores- 
cenee. Muississipp1: Bayou Porto, Tracy, no. 3795. Kansas: Riley

ADDITIONS TO THE FLORA OF CONNECTICUT. 
Since the publication in 1910 of the Catalogue of Flowering Plants 
and Ferns of Connecticut,! a large amount of exploration has been 
done in the state and several previously unknown or inaccessible col- 
lections have been examined. The present article is an attempt to 
put the more important results of this work on record.’ It includes 
reports of 88 indigenous and of 72 introduced species, varieties and 
named forms not included in the former publication. These have 
been marked, the native plants with an asterisk and the introduced 
plants with a dagger, in the following list.

2In the case of records not here published for the first time, reference has been made 
in parenthesis to the original publication.
