[NOTE: the GPS coordinates and altitude recorded here were provided with the next collection, NACPEC19-037, since the two appear to share the same habitat and associated taxa and were very likely growing near one another; GPS coordinates provided (37.880126 deg. N, 83.758067 deg. W) are clearly not correct for this collection, but appear to be at the same site as the previous collection, NACPEC19-035; altitude provided, 236 meters, is also very close to the previous collection and unlike that of the following one. -SBL]
