Imagine Sligo Creek Park 100 years ago and you may not envision bogs and swamps or a floodplain instead of a Parkway or no English Ivy but Japanese honeysuckle that was already "common everywhere." These are among many fascinating features of an earlier Sligo one can glean from “A Flora of the Sligo Valley,” completed in 1940 by local botanist Charles Lester Floyd. His Flora documents about 400 native and introduced species from his own observations and from historical collections dating back to the 1870s. Natural History chair Michael Wilpers stumbled across this fabulous resource at the Takoma Park Library. It's now on our website, thanks to webmaster Clair Garman, with indexes to the plant families and hot links to the relevant pages of the Flora.
