Halesia Ellis ex L.
carolina L. [Little Silverbell]
SY=Halesia parviflora Michx.
diptera Ellis [Two-winged Silverbell]
SY=Halesia diptera var. mangniflora Godfrey
tetraptera Ellis [Carolina Silverbell]
var. monticola (Rehd.) Reveal & Seldin
SY=Halesia carolina L. var. monticola Rehd.
SY=Halesia monticola (Rehd.) Sarg.
SY=Halesia monticola var. vestita Sarg.
According to Wilbur Duncan (1988): "Use of the less familiar name, H.
tetraptera, for this species instead of the commonly used H. carolina may
cause confusion; but under the rules of nomenclature this change should be
made since specimens of Silverbell from the locality where the original
collection was made have corollas 14-18 mm long."
According to Robert Godfrey (1989): "Use of the name H. carolina, herein is
in accordance with the nomenclatural analysis of Reveal and Seldin (1976)
and according to them the name for the plant designated H. carolina in
recent manuals is H. tetraptera Ellis."
H.t. monticola seems to refer to the exceptionally large specimens in the
Sorry, but I don't have access to Reveal and Seldin.
Your trees are H.t. of both varieties.
