Origin of Species Name
Adjective (Latin), slashed into narrow divisions with tapering, pointed incisions (Stearn 1973).
General Environment
This is a marine species.
Description
Plants saxicolous, arising from small primary holdfasts and short erect stipes, the dorsiventral blades developing perpendicularly from the stipe, therefore prostrate and spreading, with branch tip, margin and laminal ventral secondary holdfasts attaching to rocky substrata or other thalli to form an imbricating mat; blades firm, smoothly textured, brownish-red in color, with occasional marginal dentations that are the precursors to adventitious branches; blades initially transversely ovate to angular, 0.6-1.6 cm wide, the primary blade then proliferating finger-like branches from distal margins; blades 270-500 µm thick, the medulla densely filled with long, thin filaments from 2-5 µm in diam. with occasional connecting stellate ganglia; cortex 3-4 layered with irregular to subglobose large inner thick-walled cortical cells 28-36 µm diam., grading to smaller-celled outer cortical cell layers, the heavily pigmented surface cells irregularly rounded to spherical and small, 3.5-5.0 µm in diam., arranged in a mostly continuous cortex of arching rows in surface view, the chloroplasts at times reticulate; gametophytes presumably dioecious, spermatia spherical to elongate, 1.5-3.0 µm diam., produced from outer cortical cells in small rounded to irregular and slightly raised, pigmented sori on dorsal surfaces; female characteristics, carposporophytes and tetrasporangia unknown.
