ADDITIONS TO THE FLORA OF WORCESTER 
COUNTY, MASSACHUSETTS. — II. 
ROLAND M. HARPER. 
SINCE the publication of my first article under the above title 
(Ruopora, 1: 42, 43), I have succeeded in finding several more 
plants not previously known in Worcester County, and have at the 
same time somewhat extended the ranges within the county of most of 
the plants mentioned in that article. The recent revision of several 
groups of New England plants has also furnished some material for the 
present article. 
During the year Dr. G. E. Stone has published a Flora of Lake 
Quinsigamond, which contains several plants not before recorded 
from Worcester County. Some of these I have collected also, in other 
parts of the county, and I have indicated them below by an asterisk.

Jackson's 1894 catalogue of Worcester County plants : —
