The holotype of Arctostaphylos hooveri P. V. Wells, cited as having been deposited in the Robert F. Hoover Herbarium, California Polytechnic State University (OBI), apparently is not extant. The isotype deposited in the University Herbarium (UC) at the University of California, Berkeley (Hoover & Wells 1960 — UC 1218855) is designated as the lectotype, and the isotype in the California Academy of Science Herbarium (CAS 423565) is thereby an isolectotype. Hoover 8520 (OBI 175682) is recognized as a paratype.
