The Articulated and Non-Articulated Stem in Selaginella (Selaginellaceae - Lycopodiopsida)
American Fern Journal, 2018The present investigation presents a clear differentiation between the articulated and non-articulated stem of Selaginella, based on morphological and anatomical characteristics. We also take the first step in developing a clear definition of the articulated stem in Selaginella.

On the typification of three Isoetes names (Isoetaceae, Lycopodiopsida) described from France
PhytotaxaThis paper deals with typification of three species names in Isoetes described from France: the lectotype previously designated for I. delalandei J.Lloyd is here superseded by another lectotype according to new evidence, and lectotypes are designated for I. echinospora Durieu and I. tenuissima Boreau.

We describe and illustrate Selaginella kriegeriana, a narrow endemic species from Caparao National Park, Brazil, and discuss its affinities. Scanning electron micrograph images of spores and leaves supplement our discussion. In addition, we present a synopsis of the Selaginella species from Caparao National Park, with an identification key and ...

Two new endemic Isoetes from Zhejiang, China, Isoetes changleensis (2n = 22) and Isoetes yuhangensis (2n = 22), are described and illustrated. The morphological characteristics of I. changleensis, such as the presence of tuberculate and irregularly rugulate megaspores having a broad equatorial band with densely rugulate ornamentation, make it easy to ...
