It is known by the common names Faxon yucca,[3] Spanish dagger,[3] and giant dagger.[4] TaxonomyThe species has been called Yucca torreyi – a name given in 1908 by John Shafer.[1] The epithet commemorates John Torrey, a 19th-century American botanist who designated this as a new variety in 1859.[5] Y. torreyi is now regarded as an illegitimate name; however sources differ as to the correct name, using either Yucca treculeana Carrière[6] or Y. faxoniana.[1] DistributionYucca faxoniana is native to the Chihuahuan Desert region of northern Mexico, southern New Mexico, and southwestern Texas. Its range is centered around Big Bend National Park in the central Rio Grande valley in the Chihuahuan Desert. It is found mainly in the Mexican states of Chihuahua and Coahuila, but also minor locales of Durango and Nuevo León. It does not occur in the upper Rio Grande Basin section in central New Mexico, nor the lower third of the Rio Grande Valley towards the Gulf of Mexico.[3]DescriptionThe plant generally is a multitrunked shrub {{convert|3|-|10|ft|m}} in height. They can be single trunked and tree-like to {{convert|20|ft|m}} tall. The bladed leaves range from {{convert|2|to|4.5|ft|m|1}} in length. The flowers, ivory to creamy white and bell shaped, are on a flower head up to {{convert|2|ft|m|1}} long.[5] Flowers, pollinated by moths of the genus Tegeticula, bloom typically in April.[4] The plant produces sweet, pulpy, oblong fruits.[4] UsesYucca faxoniana fruit was used by the Apache people as a food source, raw and prepared in various ways. They also used the plant leaves as a fiber in basketry, cloth, mats, ropes, and sandals. The roots were used as a red pattern element in baskets.[5][7]References1. ^1 2 {{cite web|title=Yucca faxoniana|url=http://apps.kew.org/wcsp/acceptedRef.do?name_id=291753|work=World Checklist of Selected Plant Families|publisher=The Board of Trustees of the Royal Botanic Gardens, Kew|accessdate=27 February 2012}} 2. ^{{cite web|url=http://www.theplantlist.org/tpl1.1/record/kew-291753|title=The Plant List: A Working List of All Plant Species|accessdate=26 January 2014}} 3. ^1 2 {{GRIN | accessdate = 2 January 2018}} 4. ^1 2 {{Cite book|url=https://www.worldcat.org/oclc/80359503|title=Little Big Bend : Common, Uncommon, and Rare Plants of Big Bend National Park|last=Morey|first=Roy|date=2008|publisher=Texas Tech University Press|year=|isbn=9780896726130|location=Lubbock|pages=40|oclc=80359503}} 5. ^1 2 NPIN — Johnson.
