Marattia howeana (W.R.B.Oliv.) P.S.Green, a rare endemic to Lord Howe
Island with only a few known remaining populations. Several marattioid fern
species, including M. howeana and the Hawaiian endemic M. douglasii
(C. Presl) Baker, are seriously threatened by introduced feral pigs who favor
the sweet fleshy rhizome as a food source. The fully fused synangia (fused sporangia,
ca. 3–5 mm in length), characteristic of Marattia s.l., are captured
in this photo just at the stage of dehiscence. This photo was taken from live
material grown at Humboldt State University, Arcata, California, where new methods
for efficient asexual propagation of marattioid ferns are currently under development.
