Comments

In the Watershed, sand verbena typically grows in foothills with sandy substrate, for instance within the Pinyon Flats campground of the Great Sand Dunes NP or close to Mountain Home Reservoiron. But on occasion it ranges up into the lower montane. Tripterocalyx micranthus is not uncommon around the Valley, on both sides. It is a Central and Southern Rockies plant. BONAP shows this remarkable species extending down the Rio Grande drainage only into Rio Arriba Co, New Mexico, but Allred et al. (2020) show it extending through New Mexico down to Doña Ana Co.
