Aliciella is a genus of flowering plants in the phlox family, Polemoniaceae (order Ericales), native to the arid and semi-arid landscapes of the western United States and northwestern Mexico. The genus encompasses approximately 23–24 species, including small annuals and perennials commonly known as gilias owing to their long history of placement within the related genus Gilia.
The genus was first erected in 1905 to accommodate a subset of gilias that appeared morphologically distinct from the broader Gilia assemblage, but it was subsequently abandoned and its members returned to Gilia. Modern molecular phylogenetic analyses have supported the original segregation, and the genus has been formally revived. The transfer of species to Aliciella was championed by botanist J. M. Porter, whose authorship appears on most current species combinations.
Species in the genus tend to occupy dry, rocky, or sandy habitats across the Great Basin, Colorado Plateau, and adjacent mountain ranges. Representative members include Aliciella latifolia (broad-leaved gilia), Aliciella formosa (Aztec gilia), Aliciella hutchinsifolia (desert pale gilia), and Aliciella penstemonoides (Black Canyon gilia). The genus is named in honor of Alice Eastwood (1859–1953), a Canadian-American botanist who worked for decades at the California Academy of Sciences and is credited with collecting the first specimen belonging to this group.
Etymology
The genus name Aliciella honours Alice Eastwood (1859–1953), a Canadian-American botanist who is credited with discovering the first plant assigned to this genus. The genus was originally described in 1905, briefly abandoned, and later revived after genetic analyses confirmed its distinctiveness from Gilia.
Distribution
Aliciella species are native to the western United States and northwestern Mexico, with most occurring in arid and semi-arid habitats of the Great Basin, Colorado Plateau, and adjoining ranges. No species are known outside this North American desert and steppe region.
Taxonomy Notes
Aliciella was originally separated from Gilia in 1905 on morphological grounds but was subsequently subsumed back into Gilia. Molecular phylogenetic work later demonstrated that the group is distinct, leading to formal reinstatement of Aliciella. GBIF places the genus in family Polemoniaceae, order Ericales, with approximately 24 accepted taxa.
