Comments

Of common horehound there have been less than ten vouchers from the Watershed, all from a fairly restricted area, in the foothills beside roads west of Antonito, especially around Los Mogotes (Conejos Co). Recent iNaturalist photorecords of Marrubium vulgare, however, indicate the current presence of Marrubium vulgare elsewhere in the Watershed: in Penitente Canyon (Saguache Co, 2 Aug 2015), in Moffat (Saguache Co, 19 July 2021), and near the Great Sand Dunes (26 July 2022). This exotic follows the Rio Grande drainage down through New Mexico and on past the Big Bend of Texas. Incidentally, the common name in English is a folk etymology, deriving from the Anglo-Saxon word harhûne, "white honey," having nothing to do with dogs.
