III.—On the Occurrence of Haliserites in the Upper Silurian and Upper Devonian Rocks of Victoria, Australia

Abstract

During the last few years there have passed through my hands for determination many specimens of a twig-like fossil-plant from the highest Silurian flaggy-sandstones of Victoria. These were usually too fragmentary to afford any very decided evidence as to their affinity, although their surfaces showed a close-textured and well-defined structure, referable to that of prosenchymatous wood-cells, and the stem had a definite central vascular axis, such as was first noticed by Hugh Miller in similar fossil remains from the Old Red Sandstone of Scotland.
