Massachusetts Vascular Plants
About. Copyright Notice and Acknowledgements

The flora of Massachusetts embraces more than three thousand species of vascular plants including non-natives. Taxonomy in this view largely follows Massachusetts County Checklist of 2011. As of today, the gallery contains 37,080 photos of 2,190 taxa (species, subspecies, varieties, and hybrids) mostly from southeastern Massachusetts. Species flagged exotic and cultivated are excluded from the count, thus leaving 2,066 species from the flora of Massachusetts. However, this filtering is not applied to thumbnail views. In other words, links to genera and families may lead to photos of some exotic/cultivated taxa, for example, those previously erroneously included in the flora (such as exotic willows Salix pentandra or S. aurita).
