Rank Reasons
Allium burlewii is a southwestern California endemic and is restricted to high elevation slopes. It is fairly well-collected but there is not enough information to estimate how many distinct populations there are.
Range Extent Comments
Southern high Sierra Nevadas, Tehachapi Mountain Area, Inner South Coast Ranges of southwestern California (Hickman 1993).
Occurrences Comments
The precise number of distinct occurrences is unknown; there are 117 accession records in the California Consortium of Herbaria as of March 2007; 55 of these have been collected since 1970.
Ecology & Habitat
