Order Corallinales

Family Corallinaceae

Subfamily Corallinoideae

Jania subulata (Ellis & Solander) Sonder 1848: 186

Plants pink, rather delicate, to 5 (-7) cm tall, profusely branched, with complanate axes and proliferation of short terminal branchlets, holdfast crustose. Branching dichotomous in main axes, with pinnate (opposite) branching in subsidiary axes; numerous terete or slightly compressed terminal branchlets impart somewhat feather-like appearance to axes. Basal segments terete to slightly flattened, 100-250 µm diameter; middle segments compressed, 0.7 – 1.0 mm diameter, 0.3-0.7 mm long. Branchlets terete to flattened, 100-300 µm in diameter, forked or unbranched, often tapering distally. Intergenicula inconspicuous. Conceptacles in distinctly swollen (to 400 µm diameter) terminal segments of axes or branchlets, often with lateral branchlets around them.
