Carex specuicola is a rare species of sedge known by the common name Navajo sedge. It is native to a small section of the Colorado Plateau in the United States, its distribution straddling the border between Utah and Arizona, and completely within the Navajo Nation. There are several populations but they are limited to a specific type of habitat. The plants grow from the sides of steep, often vertical cliffs of red Navajo Sandstone, in areas where water trickles from the rock. It occurs at elevations between 5,700 and 6,000 feet, usually in shady spots. Though it is not a grass, the sedge grows in inconspicuous clumps resembling tufts of grass sticking out of the rock face. When the sedge was federally listed as a threatened species in 1985, it was known from only three populations in Coconino County, Arizona, with no more than 700 plants existing. The species has since been observed in northeastern Arizona and San Juan County, Utah.
Scirpus ancistrochaetus is a rare species of flowering plant in the sedge family known by the common names barbedbristle bulrush and northeastern bulrush.

It was also believed extirpated from the state of New York, but at least one population has been rediscovered in Steuben County in 2010. It is threatened by the loss and degradation of its wetland habitat. It is a federally listed endangered species.
