Introduction

The purpose of this work is to highlight historical observations of the various plants found within Massachusetts in an effort to classify their native range and population distributions. Its other intent is to develop an accurate etymology of historical Latin names to the present day. For most plants, we will be using Florula Bostoniensis written by Dr. Jacob Bigelow as a launching point for naming conventions and status within Massachusetts. While his book was originally intended to classify plants within 5-10 miles of Boston, Bigelow later expanded his range to many parts of New England. There are many interesting observations of rare plants and those species unique to the alpine zones of Northern New England, but here I only include those that are native to Massachusetts. There should be no plants listed here that are not native to the state. To build a complete picture, I chose the earliest floras from Middlesex County, Worcester County, and Berkshire County as historical markers for various regions of the state: east, central, and west respectively. I have broadly included the southeastern coastal region as part of the east in several descriptions, but be advised that most plants that often appear in this plant community will be ones that prefer dry or sandy soils. The range of all species come from the field guides cited below or GoBotany, when no physical information could be found. This document is organized according to the Vascular Plants of Massachusetts: A County Checklist which is the authoritative list of the plants known to Massachusetts.
