Abstract

The anatomy of branch and main stem connections, with respect to the spatial relation of central strands, was studied in four species of pleurocarpous mosses: Climacium americanum, Climacium dendroides, Rhytidiadelphus triquetrus, and Rhytidium rugosum. In each of these species the central strand consisted entirely of hydroids. Fresh specimens obtained in Iowa and Wisconsin were fixed in CRAF III. To soften tough cell walls, samples were soaked in concentrated (50% aqueous) hydrofluoric acid for one week prior to dehydration in ethyl alcohol. Paraffin (61°c mp) was used as the embedding medium. In the several branch connections studied for each species there was no direct connection between stem and branch central strands.
