'''''Langloisia''''' is a genus of flowering plants in the family Polemoniaceae. It is monotypic, being represented by the single species '''''Langloisia setosissima''''', also known as '''bristly langloisia''', '''bristly-calico''', '''Great Basin langloisia''', and '''lilac sunbonnets'''. It is native to the western United States and north-western Mexico,<ref name="POWO">{{cite web |title=''Langloisia'' Greene {{!}} Plants of the World Online {{!}} Kew Science |url=https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:294680-2 |website=Plants of the World Online |language=en}}</ref> where it is found in desert washes and on rocky slopes and plains from eastern Oregon and Idaho, south via Nevada and Utah to eastern California and Arizona.
The genus name of ''Langloisia'' is in honour of Auguste Berthélemy Langlois (1832–1900), who was a French-born American clergyman and botanist.<ref>{{cite book | last=Burkhardt | first=Lotte | title=Eine Enzyklopädie zu eponymischen Pflanzennamen |trans-title=Encyclopedia of eponymic plant names | publisher=Botanic Garden and Botanical Museum, Freie Universität Berlin | year=2022 | isbn=978-3-946292-41-8 | url=https://doi.org/10.3372/epolist2022|format=pdf |language=German |location=Berlin | doi=10.3372/epolist2022 |access-date=January 27, 2022}}</ref>

It is an annual plant, growing to 4–20 cm tall. The leaves are spirally arranged, linear, 2–3 cm long, densely bristly and with a toothed margin. The flowers are white to light blue or pale purple in color, 1.5–2 cm diameter, with a deeply five-lobed corolla.
There are two subspecies: *''Langloisia setosissima'' subsp. ''setosissima''. Flowers with a uniformly colored corolla, possibly showing faint patterns of dots and stripes. *''Langloisia setosissima'' subsp. ''punctata'' (syn. ''Langloisia lanata, Langloisia punctata''). Flowers with a corolla spotted with darker purple and yellow.
The genus Loeseliastrum was previously included in Langloisia, formed from two former ''Langloisia'' species:<ref name="POWO"/><ref>{{cite journal |title= Segregation of LOESELIASTRUM from LANGLOISIA (Polemoniacae) |author= Steven Timbrook |journal= Madroño |volume= 33 |number= 3 |date= July 1986 |pages= 157–174 |publisher= California Botanical Society }}</ref> * ''Loeseliastrum matthewsii'', formerly ''Langloisia matthewsii'' * ''Loeseliastrum schottii'', formerly ''Langloisia schottii''
