Cuba, Jamaica, and parts of South America. The species belongs to the heterophyllous subg. Stachygynandrum, which is characterized by the stems (at least distally) and the vegetative leaves of branches having 2 rows of smaller, usually appressed, median leaves and 2 rows of larger, spreading lateral ones. Contrasting with this is subg. Selaginella, with plants homophyllous throughout, i.e., leaves are borne on all sides of the stem and branches and all are appressed for most of their length. Subgenus Stachygynandrum is sharply divided into two groups, one having stems articulate, or at least constricted at or near the nodes and here usually discolored, and with rhizophores produced dorsally. The other group, containing S. pallescens, has stems neither articulate nor with discolored or constricted nodes, and with rhizophores produced ventrally, Selaginella pallescens and its nearest relatives commonly have the stems densely caespitose, often forming rosettes. They tend to curl inward when dry, then uncurl again when moisture is introduced, thus giving rise to the common name Resurrection Plant. Taxonomy of the entire S. pallescens complex in the neotropics needs careful re-examination. There are several species which I feel are not truly distinct, and yet there are some hitherto unrecognized variants, which perhaps should be formally treated as varieties or forms. Some very closely related species are: S. cuspidata (Link) Link and var. elongata Spring, S. harrisii Underw. & Hieron., S. microdendron Bak., S. millspaughii Hieron., and S. pulcherrima Liebm. During a study of the genus for the Ferns and Fern Allies of Guatemala, it appeared to me that most of these species might better be included under S. pallescens, for whatever differences were noted by previous authors appear to be thoroughly inconsistent. On the other hand, some new features have come to light which seem significant and consistent enough to indicate recognition of some specimens at the varietal level. In his study of the spores of heterophyllous Selaginellae, Hellwig (Ann. Mo. Bot. Gard. 56:41/1 164. 1969) annotated a number of specimens in various herbaria as S. pallescens, red-stemmed variant. Some other minor features have been discovered to be consistent with stem color on these specimens, and the combination of
