Taxonomic Comments
Allium incomptum is described by Kierstead and Lindstrand (2022). "This new species is most similar to Allium yosemitense Eastw., but differs by several features including its shorter pedicels, narrow, blunt tepals, and markedly exserted stamens, contrasted with the longer pedicels, acute tepals, and stamens not or barely exserted in A. yosemitense. The two species have widely disjunct geographic ranges in California" (Kierstead and Lindstrand 2022).
