Description
Stem c. 450 u in diam. Branchlets 6 in a whorl, three and partially four times forked. Primary rays (diam. c. 175-225u) usually more than half the length of the branchlets; secondary 5-6; tertiary 4-5; quaternary and quinary usually 3 (diam c. 60-80). Dactyls uniformly 2-celled, the lower cell long cylindrical, c. 60-70 u in diam., the upper (normally) similar,slightly thinner, and but little shorter, with a very acuminate point.
Monoecious, the gametangia produced at all the nodes, but male and female not seen together. Oogonia solitary, c. 500 u long (excl. cor.), 375u broad; coronula, c. 65 u broad, 40 u high, the cells irregular. Oospore light brown golden brown, c. 330 u long, 315 u broad, 225 u thick, showing eight firm low ridges; membrane irregularly and angularly coralloid.reticulate, with about seven meshes between the ridges. Antheridium c. 350 u in diam.
The most remarkable and distinct species in the collection, the whorls large and spreading, as much as 6-7 cm. across, the sterile and fertile similar, the whole of the younger part of the plant enveloped in a dense cloud of mucus.
