Photo by Edward Beckwith, from https://www.flickr.com/photos/exploreplants/4150005847 This work is in the public domain in the United States because it was published in the United States between 1928 and 1977, inclusive, without a copyright notice. For further explanation, see Commons:Hirtle chart as well as a detailed definition of "publication" for public art. Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (50 p.m.a.), Mainland China (50 p.m.a., not Hong Kong or Macao), Germany (70 p.m.a.), Mexico (100 p.m.a.), Switzerland (70 p.m.a.), and other countries with individual treaties. The back of the print only inscribes "A-36 Florencio Tamesis Philippine Forestry Bureau 12/12/39", but without any signs of copyright marks, therefore this photograph lapsed into public domain.
