FIGURE 7 in Fern distributional records in Christensenia (Marattiaceae), Dipteris (Dipteridaceae), and Rheopteris (Pteridaceae) from the upper Sepik of Papua New Guinea
FIGURE 7. Christensenia aesculifolia (Blume) Maxon subsp. korthalsii (deVriese) Rolleri. A, sori; B, frond undersurfaces. Among marattioid ferns, Christensenia is unique in its reticulate venation, pedate fronds, circular synangia, and creeping rhizomes (Murdock 2008). A from Takeuchi, Ama & Gambia 25795; B from Takeuchi, Ama & Gambia 25315.
