Description
Blades decumbent, 10-30 cm high, 500-1200 microns thick in the upper to lower portions, irregularly dichotomously divided four to twelve times, with segments 1-4 cm in width, with or without marginal proliferations, deeply rose-red or deeply reddish-brown, fleshy, tough, internally multiaxial; the proliferations (when present), simple, laciniate (up to 2 mm in length) or dichotomously divided two to four times, foliose (up to 7 cm in length). Reproduction as for the genus. Tetrasporangial initial cut off basally from the parental cell; tetrasporangia scattered over the middle to upper portions of the blade, narrowly ellipsoidal, 38-45 microns in length, 15-20 microns in diameter. Gametophytes dioecious, producing reproductive structures over the middle to upper portions of the blade; spermangia ellipsoidal, 4-5 microns in length, 3-4 microns in diameter; carpogonial branch usually three-celled occasionally two- or four-celled, rarely with a sterile lateral; auxiliary-cell complex present; cystocarpic protruberances numerous on the dorsal surface (a few on the ventral surface and margins), 1.5-2.0 mm in height, 1.5-2.8 mm in diameter, with one or two cystocarps 750-850 microns in height by 700-800 microns in diameter (including an enveloping tissue 50-80 microns in thickness); carposporangial chains unbranched or occasionally branched once, consisting of up to seven cells.
