Question: Who was the mountain, in whose vicinity the rare plant Oreoxis humilis is only found, named after ?
Context: Redrock Mountain Natural Area Preserve is a 640 acre Natural Area Preserve located in Smyth County, Virginia.  The preserve is named for the 4413 ft Redrock Mountain, which itself is named for its red siltstone cliffs.  It supports a number of rare natural features, and two natural community types, including examples of "mountain/piedmont basic woodlands" upon the mountain's slopes, and "rich cove/slope forests" in the preserve's lowlands.  Five rare plant species are found on the property, including spring blue-eyed Mary ("Collinsia verna"), fringed scorpion-weed ("Phacelia fimbriata"), and Carey saxifrage ("Saxifraga careyana"). Mount Everett at 2,602 ft - or 793.1 m - is the highest peak in the south Taconic Mountains of Massachusetts, Connecticut and New York.  The mountain is known for its expansive views of the southern Taconics and Berkshires; for its old growth pitch pine and scrub oak; for the Appalachian Trail's north-south traverse of its shoulders and summit grounds, and for its rare plant and animal communities.  The mountain is named after a 19th-century governor of Massachusetts, Edward Everett.  The name was proposed in 1841 by Edward Hitchcock, geologist to the state, in his "Final Report on the Geology of Massachusetts."  Hitchcock wrote that at the time of his proposal, the mountain was known as Bald Mountain or Ball Mountain.  Some old maps at the Sheffield Historical Society also label the mountain as "The Dome". Oreoxis humilis is a rare species of flowering plant in the carrot family known by the common name Rocky Mountain alpineparsley.  It is endemic to Colorado in the United States, where it is known only from the vicinity of Pikes Peak.  There are three occurrences, for a total population of about 4240 individuals. Pikes Peak is the highest summit of the southern Front Range of the Rocky Mountains, in North America.  The ultra-prominent 4302.31 m fourteener is located in Pike National Forest, 19.3 km west by south (bearing 263°) of downtown Colorado Springs, Colorado.  The mountain is named in honor of American explorer Zebulon Pike, who was unable to reach the summit.  The summit is higher than any point in the United States east of its longitude. Totoket Mountain, with a high point of (est.) 720 ft above sea level, is a traprock massif with several distinct summits, located 7 mi northeast of New Haven, Connecticut.  It is part of the Metacomet Ridge that extends from the Long Island Sound near New Haven, north through the Connecticut River Valley of Massachusetts to the Vermont border.  Totoket Mountain is known for its 500 ft scenic cliffs, unique microclimate ecosystems, rare plant communities, and for Lake Gaillard, a 2.5 mi public reservoir nearly enclosed by the mountain.  The north ridge of Totoket Mountain is traversed by the 50 mi Mattabesett Trail and a significant network of shorter trails.  The name "Totoket Mountain" applies to both the entire mountain and to a subordinate northwestern peak (577 ft ). Iris arenaria (sand iris) is a species in the genus "Iris"; it is also in the subgenus of Iris and in the "Psammiris" section.  It is a rhizomatous perennial, from Central Europe, found in Hungary, Austria, Romania, Czech Republic and Ukraine.  It has grass-like leaves, a short stem and pale yellow flowers.  It has had a mixed origin and was once "Iris humilis subsp.  arenaria", a subspecies of "Iris humilis" (another Psammiris iris), until it was reclassified as a separate species.  But many sources still state that it is either a synonym or subspecies of "Iris humilis".  It is cultivated as an ornamental plant in temperate regions. Dudleya stolonifera is a succulent plant known by the common name Laguna Beach liveforever.  This is a rare plant which is endemic to the coastline of Orange County, California.  It is known from only about six populations in the vicinity of Laguna Beach, totalling about 30,000 individuals.  It is federally listed as a threatened species of the United States. The longleaf pine ecosystem is a diverse fire climax conifer pine dominate habitat that includes many rare plant and animal species found within the southeastern United States.  Once a dominant ecosystem of the southeastern portion of the United States, it now occupies less than a quarter of the original range.  Degrading of the ecosystem is partially due to excessive timber harvesting, urbanization, and fire exclusion.  Although the ecosystem is broken up in present time, it still carries various plant and animal species.  Many of the relevant species found in the longleaf pine ecosystem can be found in the ecosystem alone.  The great concern for the ecosystem at the present is the continuation and health of the overall plant and animal species which reside within the area.  The use of a range of techniques, including planting longleaf seedlings, introducing prescribed burning regimens, managing native ground cover, and controlling invasive species within the ecosystem can help to preserve this threatened ecosystem. Scorzonera humilis, the viper's-grass, is a perennial plant.  In Britain it is a rare plant, restricted to moist meadows, in Dorset and Warwick in England, and in South Wales. Minuartia cumberlandensis is a rare species of flowering plant in the pink family known by the common names Cumberland stitchwort and Cumberland sandwort.  It is endemic to the Cumberland Plateau near the Big South Fork of the Cumberland River in Tennessee and Kentucky.  This rare plant is found only in cool sandstone rock shelters, on the moist sandy cave floors behind the drip line.  There are 27 occurrences in Tennessee and one in Kentucky.  The plant is a federally listed endangered species.
