Flora Pittsburghensis




This site is meant to be an illustrated reference to the flowering plants of the Pittsburgh region. (For now, at least, we are leaving out grasses and sedges.) Obviously it’s in the early stages of construction, so its more a concept than a reference at the moment.

We have taken as a base A Preliminary List of the Vascular Flora of Allegheny County, Pennsylvania, by John Adolph Shafer, which was published by the Carnegie Museum in 1901.The book is obviously out of date, but it remains the most accessible tolerably complete list of the plants of the Pittsburgh area.

Descriptions are filled in from our own observation and from the posthumous seventh edition (1908) of Gray’s New Manual of Botany, heavily edited and updated by Benjamin Lincoln Robinson and Merritt Lyndon Fernald.
