ZIZIA CORDATA “rather common in all our open woods," Pine Plains; 
also at various stations in Connecticut. 
TAENIDIA INTEGERRIMA, frequent in gravelly or rocky woods, 
Dutchess County, N. Y.; wooded banks of Housatonic River, Ct.; 
also in western Vermont. 
PorEgMoNiUM VAN BRUNTIAE, swamps, Salisbury, Ct.; also western 
Vermont. 
VALERIANA ULIGINOSA “very abundant in some of the marshes and 
swamps about Pine Plains," over an area 12 miles in diameter, one 
of the stations within three miles of the Massachusetts-Connecticut 
line, growing in swamps with Salix candida and Betula pumila; also 
locally in Vermont. (Abundant in the calcareous swamps of northern 
Maine and locally across central and western New York.) 
Surely some, if not all, of these characteristic plants of the cal- 
careous regions are to be found in Berkshire County. All of them are 
in good condition for collecting in late May or June and a party of 15 
or 20 enthusiastic explorers should in two or three days of active 
raking of southern Berkshire bring them to light. The best regions 
are naturally the least accessible by railroad or trolley, consequently, 
it is hoped that those who have automobiles will feel ready to put them 
at the disposal of the Club in order to reach the more remote areas 
away from railroads. 
A notice stating the headquarters of the Club for this trip and other 
details as to times of trains, ete., will be prepared later. All who wish 
this final notice should notify R. C. BEAN, 48 Emerson Street, Wake- 
field, Mass.
