Dear colleagues, In an Early Holocene deposit, with recognisable charcoal of Pinus (cross section of Coniferous type with raisin channels) and Betula (cross section with scalariform perforation plates and rays of two cells wide) in a thin section, my colleague Hans Huisman who studied these thin sections found charred plant remains with in several cases seemingly a concentric pattern of leaves. Does any of the photo's in the attached PPTX-file ring any bell? Never mind the text sheets in Dutch, they merely announce what's coming next. The last slide shows a longitudinal section which might also give some hints, although it is not certain if this belongs to the same plant. Any hints would be highly welcome, With kind regards, oTTo
