Epilobium nevadense explained

Epilobium nevadense is a rare and vulnerable species of flowering plant in the willowherb family Onagraceae. It is known from a few scattered populations in mountain ranges in Nevada, Utah, and northwestern Arizona. It grows on talus slopes composed of either volcanic or limestone origin from 5200–9000 feet in elevation.^{[1] [2] [3] [4] [5]}

The nearest known relative of Nevada willowherb is Snow Mountain willowherb (Epilobium nivium), which has a similar appearance and grows in similar habitats. These two species together form Epilobium sect. Cordylophorurn subsect. Petrolobium and have been shown to form infertile hybrids in cultivation.^{[6] [7]}
