| Abstract: |
Pollen, phytolith, and starch analyses were carried out on 12 samples from two trenches in Old Kiyyangan Village, Ifugao Province, providing evidence for human activity from ca. 810750 cal. B.P. Seed phytoliths and endosperm starch of cf. rice (<i>Oryza sativa</i>), coincident with aquatic Potamogeton pollen and sponge spicule remains, provide preliminary evidence for wet-field cultivation of rice at the site. The first rice remains appear ca. 675 cal. B.P. in terrace sediments. There is a marked increase in these remains after ca. 530470 cal. B.P., supporting previous studies suggesting late expansion of the cultivation of wet-field rice in this area. The study represents initial, sediment-derived, ancient starch evidence for <i>O. sativa</i>, and initial, sediment-derived, ancient phytolith evidence for this species in the Philippines.
