1903] On the twelfth List of New England Plants 235 
FURTHER NOTES ON THE TWELFTH PRELIMINARY LIST oF NEW 
ENGLAND PLants.— Most local lists of plants of central and south- 
ern New England have reported more or less definitely both Cerastium 
vulgatum and C. viscosum. But these reports must in most cases 
have rested upon some misunderstanding of the characters of these 
plants. The larger-flowered longer-pedicelled plant of the two (the 
Cerastium vulgatum of recent American works) is very common 
throughout New England, but the other species would according to 
our present knowledge, appear to be very rare in our region. After 
examining the CazyopAy//aceae in many of the larger herbaria of New 
England the writer has been able to find only one specimen of the 
true C. viscosum from any New England locality. This is a bit col- 
lected at Providence in 1845 by Calder and preserved in the collec- 
tion of Professor W. W. Bailey, now incorporated in the Herbarium 
of Brown University. 
Stellaria longipes is another species reported in the older lists for 
various parts of New England, but this is certainly due to erroneous 
determinations of S. graminea made by persons consulting works like 
Wood's Classbook, from which the latter species is omitted. 
A careful re-examination of the distinctions between Arenaria 
serpyllifolia and its so-called variety fenuior seems to show them of 
specific value and to make it desirable to classify the latter as a 
species under its first specific name, A. /eptoclados, Guss. To the 
differences of leaves and inflorescence noted in the Synoptical Flora, 
the following distinctive traits may be added. In A. serpyllifolia the 
capsule at maturity is decidedly flask-shaped, and the walls are of a 
rather firm texture. In 4. Zeptoc/ados (in which the whole flower is 
only half to two-thirds as large as in A. serpyllifolia) the capsule is 
subcylindric, and its walls are papery. 
Lychnis alba, Mill, may now be definitely recorded from New 
Hampshire (Starrking, Mrs. E. 4. Zerry) and L. Flos-cucult, L., 
from Vermont (Greensboro, Miss H. M. Hodge), specimens from 
these localities having been kindly deposited in the Gray Herbarium. 
Tetragona expansa, Murr., was recently observed by Professor H. 
L. Clark as a transient ruderal plant. near Woods Hole, Massachu-
