Macerations of fragmented plant compressions of Silurian (Llandoverian) age yield sheets of organic material bearing ridges and depressions (interpreted as corresponding to surficial dimensions of cells), fragments of smooth walled tubular elements, and fragments of tubular elements with differentially thickened walls ("banded tubes"). A fragment of tissue (1.2 mm long), consisting of smooth walled tubes (17 + 6.9 Am in diameter), surrounding 2-3 larger (18.8 + 2. 1 Am in diameter) banded tubes… Expand
