Homosporous pteridophytes differ from seed plants most strikingly in their potential ability to produce completely homozygous offspring from a single haploid spore. The Lycopodiaceae share this characteristic with the ferns, but differ from them in t

Based on three endemic diploid spleenwort species-mountain spleenwort, Aspienium montarum Willd., ebony spleenwort, A. platyneuron (L.) B.S.P.; and walking fern, A. rhizophyllum L-a hybrid polyploid system of great complexity has developed, involving

SynopsisPteridophytes with subterranean sexual stages exist in five families. Their prothalli grow underground without light, nourished by fungi, and are rounded, massive, and without chlorophyll. Various authors have suggested that such gametophytes

Chromosome studies of pteridophytes had their major impetus in the work of Irene Manton (1) who was the first to show the far-reaching significance of Polyploidy in these plants. Her work was followed not only by numerous investigations by her own st

Biologists generally agree that species are to be delimited on the basis of genetic discontinuities. The two species concepts that depend on such discontinuities to delimit species are the biological and the evolutionary species concepts. A biologica

Geographical, ecological, morphological, and cytological observations indicate that the peculiar Central American fern, Pleuroderris michleriana (D. C. Eaton) Maxon arises by hybridization between Tectaria incisa Cav. and Dictyoxiphium panamense Hook
