This is my personal check-list. Betty Wright has a longer list. The goal is  eventually to publish a combined list. Plants are listed according to Latin family names  as laid out and described in "The Vascular Plants of Massachusetts: A County Checklist", by Bruce A Sorrie and Paul Somers (1999), with the exception that I have listed Monocotyledon families in the main body of Angiosperms (flowering plants) but distinguished by being in blue. It is hoped to expand beyond vascular plants to mosses and fungi. This list is currently very weak with regard to grasses (Poaceae)  sedges (Cyperaceae) rushes (Juncaceae) and some other groups. Comments and corrections are invited, as are offers of help to expand this survey.  N or I indicates whether the plant is native or introduced.  P in the right hand column says that there is a photo record of the plant.  In Comments BW = Betty Wright, DL = Don Lubin, WL = on Mass Watch List of rare plants.  'Deane' = refound from Deane's list from area surveyed by Drayton.
