324 FLORA OF TASMANIA. [Alge, by W. H. Harvey. 
they taper to the base and apex, and are pretty regularly dichotomous, with more or less intermixture of lateral 
branches. The axils are all rounded, the apices attenuated and acute. Sometimes there are few or no lateral ra- 
muli; in other specimens they are numerous, and frequently strongly hooked backwards, or converted into clasping 
tendrils. The cystocarps are sessile on the branches, and mostly tipped with a strong subulate horn. The colour 
is a dark brown-red. The substance is firm, and the plant imperfectly adheres to paper in drying.

| Fronds 6-8 inches long, and as much in the expansion of the lacinize, foliaceous, deeply divided in a dichoto- 
mous manner, sometimes rather irregularly multifid, the segments cuneate, from half an inch to an inch in breadth, 
the terminal lacinize gradually narrower, the apices subacute and fastigiate. Colour a rather pale rose-red, occasion- 
ally deeper. Suöstance very soft, somewhat gelatinous on the surface. The plant closely adheres to paper. The 
eystocarps, which are densely scattered over the frond, resemble those of a Callophyllis in structure.—The structure 
of the frond agrees with Agardh's description of that of his Polycelia laciniata, a plant from Western Australia, 
unknown to me, but which perhaps may be specifically as well as generically identical with what is now described. 
Not having seen a specimen of the West Australian plant, I think it best, for the present, to give a name to the 
Tasmanian. I recently distributed it as a Callophyllis, having placed it, without examination, in that genus from 
its strong external resemblance to C. discigera.—Parg CXCII. B. Fig. 1, a frond, nat. size; 2, section through
