Poa fernaldiana, also known as Poa laxa spp. fernaldiana or wavy bluegrass, is a bunch grass (forms tufts not carpets) that grows between 4 and 10 inches tall. It can be confused with Poa glauca, but the two species grow in very different habitats. P. fernaldiana is only found in alpine habitats typically near the summits of mountains, whereas P. glauca is found in various other habitats. P. fernaldiana is of conservation concern because of its restricted habitat requirements and because of its small range, New England and Northeastern Canada. Also, as of 2000, there were thought to be only 20-30 occurrences total, most in Canada, and the global population size was probably declining.
