In 2000, Dr. Madulid and Ms. Agoo made
a reciprocal visit to California to explore repatriation of
data and voucher specimens held in US Herbaria. A large
portion of the Philippine National Herbarium collections were
destroyed during WW II, and some US herbaria hold significant specimens of Philippine plants. Here, Dr. Frank Almeda, senior curator at the California
Academy of Sciences Herbarium, holds a Philippine fern voucher.
