A paper presenting a molecular phylogeny of Cystopteridaceae (including Cystopteris and Gymnocarpium, two of DMB's favorite ferns), and currently in press at Systematic Botany (Rothfels et al.
2006) consists of four well-supported clades: together, Cystopteris and Gymnocarlaium are sister to the rest of eupolypods II; Hemidictyum is sister to the asplenioid ferns; and Woodsia is sister to a large clade of onocleoid, blechnoid, and athyrioid ferns (Schuettpelz and Pryer, 2007).
This kind of longevity is quite common for species with non-chlorophyllous spores that live in xeric habitats, while mesophilic species, such as Cystopteris protrusa (Weath.
