BLOCKY phytoliths with bordered pits in Picea abies

  Thank you Zsuzsa for this post on remarkable phytoliths!     Silica reliefs of the bordered pits in Gymnosperms A cubic-like BLOCKY phytolith morphotype and its anatomical position were described in Norway spruce (Picea abies [L.] H.Karst) needles that are characteristic. These phytoliths are located in the transfusion tissue. They form a specific phytolith […]

Survey on grass phytolith identification: see the results!

  • September 26, 2019
  • Comments off

Caroline Strömberg and Tim Gallaher developed a machine learning and computer vision (ML&CV) tool for automatically identifying grass silica short cell phytoliths (GSSCP). To make this tool better than a human at identifying GSSCP, they asked phytolith researchers to take a test. You can still take this ~10-minute anonymous survey to try to identify 14 […]
