Phytoliths in the Flora of Ecuador Project: updates!

The Phytoliths in the Flora of Ecuador project was undertaken by Deborah M. Pearsall and colleagues from 1997 to 2008, with periodic work through 2012, to establish diagnostic phytolith types and phytolith vegetation signatures to enhance archaeological and paleoenvironmental phytolith applications in coastal and Amazonian Ecuador. Research was conducted in Ecuador and at the University […]

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 […]
