Two New Species Found in Colorado
Jennifer Ackerfield, the Head Curator of Natural History Collections at the Denver Botanic Gardens has written a blog about the “discovery” of two new species in Colorado. The first species, Physaria nelsonii, was collected by Melissa Islam, the then curator at DBG, in 2014 on a inventory trip to Moffat County. At that time she identified it as Physaria congesta. However, in 2021, Jennifer, thinking the species looked a little strange, changed the identification to P. nelsonii, a rare plant previously only found in Wyoming and Utah.

The second species, Penstemon bleaklyi, Jennifer collected in 2016 and photographed while on a trip to Culebra Range of the Sangre de Cristo Mountains. She uploaded a photo to iNaturalist, thinking it was a somewhat unique Penstemon. It was later identified by a New Mexico botanist as Penstemon bleaklyi.
