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 […]
