Mrs. Blanche Trask, tireless explorer of the Channel Islands, first visited San Clemente Island in October, 1896, walking the length of the island and discovering Quercus tomentella (Erythea 5: 30. 1897). She apparently also was there for a short time in October 1902; and she returned in 1903, living on the island for three months in late spring and publishing a narrative "Flora of San Clemente Island" (Bull. So. Calif. Acad. Sci. 3: 76-78, 90-95, 1904). The first set of her plants , at the California Academy of Sciences, was destroyed in the San Francisco earthquake and fire of 1906 (with the exception of a few sheets). But she apparently also sold sets of San Clemente plants, however, and they are represented at the Gray Herbarium , New York Botanical Garden, United States National Museum, and several European herbaria, including Edinburgh.
