Overview

Excerpt from The Devonian Fossils of Canada West Desm'ptiom - Stems two or three lines in diameter, branching at an angle of from 7 5 to cells variable in size, the greater number with the expanded mouth one line wide, and the circular cavity at the bottom from one-third to one-half of a line; the smaller or younger cells, of all sizes, are somewhat uniformlfidistributed among the larger. In the perfect specimens the mouths of the cells are every where in contact with each other, the edges of the walls between them sharp, and the form more or less polygonal, generally five or six sided. In worn specimens the cells are more nearly circular, and the walls obtusely rounded on the edge. The striae in the cell months not observed. I have seen only two specimens of this species, and am unable, therefore, to state to what extent the stems may vary in thickness. In S. Rayosa Hamilton Group, Iowa, the cells are distant from each other nearly their own diameter, and the stem is branched at an angle of about 55 (in the specimen figured). In S. flewuosa Niagara Group, the cells are, upon an average, more than one line and a half wide, and many of them two lines. Our species, therefore, must be regarded as distinct from either.
