PROJECT STATUS: The last installment of this atlas was published in the online journal Phytoneuron on October 14, 2014 (see link in a paragraph below). This web site will be completely re-organized to present all 4,082 New England taxa at some future date. In the interim we have posted for download a complete spreadsheet with all our records. See next paragraph below for details. In addition we will post updated genus pages with the most current distribution data as they are completed (see further below). (December 3, 2015).

Complete Spreadsheet of New England Records:

An Excel 2007 spreadsheet of all our records is now available for download at: This spreadsheet is undergoing revision and updating as the new genera pages are being created. Each record of occurrence is given a letter code for a herbarium where a voucher is located. The explanation of the letter codes is contained in an additional sheet in the spreadsheet tabbed at the bottom. The total taxa treated in our atlas are 4,082 included in 1,058 genera (582 with native species) and 186 families. Of the total taxa, 1,627 are not native to New England (inluding hybrid taxa where at least one parent was nonnative). Total hybrid taxa were 508. We will be updating this spreadsheet as new information is brought to our attention. Another 346 taxa reported in other references to be in New England were excluded from our list for the reasons noted in our various published installments. A spreadsheet of these excluded taxa is also available for download at the same link as for the our complete records. Lastly, taxa listed in our master spreadsheet for which no herbarium records are given are those for which we did not gather records due to inadequate separation in herbaria from a closely related taxon as explained in the text of our published installments.

Introduction to the Web Version

This web edition of the Atlas of the Flora of New England will be an ongoing updated document. Use the links at the top of each page to access the available sections of the atlas. We welcome information on vouchered county records of reproducing populations in habitats outside of cultivation not reflected in this atlas. The first five installments were published in Rhodora (the journal of the New England Botanical Club) in Volume 98, No. 893 on pages 1-79 (Winter 1996 [April 1997]), Volume 100, No. 902 on pages 101-233 (Spring 1998 [August 1998]), Volume 102, No. 909 on pages 1-119 (Winter 2000 [Feb. 2000]), Volume 109, No. 939, on pages 237-360 (Summer 2007 [Sept. 2007]) and Volume 112, No. 951, on pages 244-326 [Nov. 2010]. The eighth installment was published in Rhodora, Volume 113, No. 956, on pages 419-513 [Feb. 21, 2012]. The six, seventh, ninth, tenth, eleventh, twelfth, thirteenth and fourteenth installments have been published in the online publication Phytoneuron at Phytoneuron (2011-12: 1-16 + figs. 1-53 (maps)), Phytoneuron (2011-53: 1-13 + figs. 1-18 (maps)), Phytoneuron (2012-34: 1-39 + figs. 1-56 (maps)), Phytoneuron (2012-81: 1-25 + figs. 1-31 (maps)), Phytoneuron (2013-2: 1-15 + figs. 1-21 (maps)), Phytoneuron (2013-45: 1-23 + figs. 1-30 (maps)), Phytoneuron (2014-21: 1-24 + figs. 1-32 (maps)), and Phytoneuron (2014-98: 1-43 + figs. 1-60 (maps)) The maps on our web site here are updated as new vouchered records are brought to our attention.

A web application that produces dot distribution maps on-the-fly from our database has been developed for this atlas by Angelo. The New England background maps for the application are adapted from a more detailed custom map provided generously by Ray Sterner whose map web site is at: The maps are in color and show topography. Lowest elevations are green and higher elevations become progressively more brown with the highest elevations purplish and white. The distributions reflect the most current state of our database. We invite curators and other researchers who are aware of herbarium records not reflected in our database to notify us of these records by e-mail. We only need to know the taxon and the particular herbarium where the voucher is located.

As an enhancement to this online atlas we will be gradually adding links to high-resolution images of herbarium specimens available at the excellent online virtual herbarium of the George Safford Torrey Herbarium (CONN) at the University of Connectict (LINK) courtesy of that institution and with generous assistance from Dr. Robert Capers. Presently links to these images are added only for the gymnosperms and the beginning of the pteridophytes. If your web browser is unable to handle these large images easily, try right-clicking on the image in your browser for additional viewing or saving-to-your-computer options. -- Revised: March 30, 2016
