The Squares of Savannah, Georgia often have a canopy of Quercus virginiana, or southern live oak. This photograph, from Chippewa Square, was one of many taken of the oaks that day. Incidentally, Chippewa Square is also the locality of the park bench scenes from Forrest Gump (I was oblivious and only learned about it later).
Like the previous Cladonia evansii, Quercus virginiana has a distribution that stretches along the coastal plain of the southeast USA. Like many oak species, it is known to hybridize; some named hybrids are listed in the Flora of North America account for the species: Quercus virginiana. The FNA account also details some of the past economic importance of the species: “…it was widely used for structural pieces in the manufacture of wooden ships, and large groves were actually considered a strategic resource by the federal government. Historically oil pressed from the acorns was utilized. Like other members of the live oak group…Quercus virginiana seedlings form swollen hypocotyls that may develop into large, starchy, underground tubers. In the past, the tubers were gathered, sliced, and fried like potatoes for human consumption”.
The epithet virginiana refers specifically to Virginia, USA. The state name, in turn, “may have been suggested…by Raleigh or [Queen] Elizabeth, perhaps noting her status as the ‘Virgin Queen’, and may also be related to a native phrase, ‘Wingandacoa’, or name, ‘Wingina'”). The etymology of virginiana was the subject of some discussion during our trip, so I hope that this clarifies the matter.
