ABSTRACT
as published by Thomas Walter in 1788. Because of the early date of this flora, many of species were new
its
t
es to represent an additional 18 Thomas Walter names.
RESUMEN
In the 1780s, Thomas Walter (1740-1789) owned and operated a rice plantation on the Santee River, Berkeley
him
County, South Carolina. His interest in the plants of the area led to compile a simple flora in which
he gave them descriptions and Latin names. This book, Flora Caroliniana (1788), the treatment of
is first
American
plants employing the binomial nomenclature and sexual classification system of Linnaeus. Of
even greater importance, the early date of this publication has given many of his names priority over those
of later authors.
This paper largely completes typification of the plant names published by Walter in his pioneer
Flora.
By the selection of type specimens to represent these names, they become fixed in their meaning, bringing
nomenclature
stability to the of this portion of the Southeastern
flora.
Walter kept no herbarium (Ward 2007a). In the absence of authentic original materials, the International
—
Code
of Botanical Nomenclature (McNeill et 2006) permits selection of another specimen a neotype
al.
to represent the missing type.
The Thomas Walter Typification Project (Ward 2006a, 2007b, 2007c, 2007d, 2008) and ancillary
studies (Ward 2006b, 2007e, 2007f, 2007g) have addressed the typification of many of the names assigned
to American plants by Walter. These studies also treat aspects of the relationship between Walter and the
Scottish horticulturist John Fraser. Fraser's herbarium (the Fraser/Walter herbarium, BM), gathered in the
Carolinas and Georgia in 1787, was briefly seen by Walter, but largely irrelevant to typification of Walter's
is
names. Selection of collections made by other persons is the only pathway to stability of the great majority
names.

In previous numbers of the Project (2007d, 2008), the Harvard University Herbaria (GH) were the
source of selected specimens. Here, for those species not adequately represented in the holdings of that
institution, the herbaria of the University of South Carolina (USCH) and Duke University (DUKE) have
provided specimens
of quality appropriate for selection as neotypes.

description. No specimen has been identified in the Fraser/Walter herbarium (BM). The species is infrequent
