Stem 1-2 feet long, in smaller specimens compressed, in larger quite flat, flexuous, rather distantly pinnately
branched, the lower branches decompound, the upper gradually simpler. Branches issuing from the flat side of the
stem, retroflexed at their insertion, distichous, alternate, bipinnate or pinuate. Fimus (and pinnules of the larger
branches) distant, naked in the lower half, zigzag, and armed with the spine-like bases of old ramuli; pinnidate in
the upper half. TJltimate pinnules or leaf-like ramuli quite flat, lanceolate or sword-shaped, 1-2 inches long, 2-3
lines wide, coriaceous, acute. Beceptacles flattened; no ripe ones seen. Vesicles unknown.
All OUT specimens gi-ew in shallow water, and therefore probably represent a dwarf form of the species, which
appears to be strikingly unlike any other described. The ultimate pinnules and receptacles are as broad as those of
Cystophora platylohiwn, and usually longer; and oui present plant differs essentially from that species in having
refracted branches issuing from the fiat side of the stem.—P l a t e CLXXXY. Fig. 1, the root and base of stem;
