Flora of Burtonmore and Worcester County, Massachusetts, USA
Index by Scientific Name
This list is not, at this time, a complete list of all possible species for Massachusetts; rather, it is selective for those I have seen or collected,
mostly in Worcester County, but also elsewhere in Massachusetts.

If a name is preceded by a symbol (Φ, λ, or Δ), clicking the symbol will bring up an illustrated page for that species
with site and observation information, links for other illustrations, and further reference.
The λ indicates a link within another species’s page; ω links to an ornamental listing.
Those species for which I have included illustrations from original sources, many of them pre-Linnean, are prefixed with the symbol Δ.
