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 pinnate. Pinne (and pinnules of the larger 
branches) distant, naked in the lower half, zigzag, and armed with the spine-like bases of old ramuli; pinnulate in 
the upper half. Ultimate pinnules or leaf-like ramuli quite flat, lanceolate or sword-shaped, 1-2 inches long, 2-3 
lines wide, coriaceous, acute. Receptacles flattened ; no ripe ones seen. Vesicles unknown. 
All our specimens grew 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 platylobium, and usually longer; and our present plant differs essentially from that species in having 
refracted branches issuing from the flat side of the stem.—PrATE CLXXXV. Fig. 1, the root and base of stem; 
2, portion of the upper region of the stem and branches : both figures the natural size.
