Our specimens are about an inch in height, and seem to 
have formed wide intricate patches on rocks. "The species is 
allied to P. intricata, J. Ag. and several of the same section, 
but cannot be included under any described species known 
to us.

cens, frondibus capillaribus membranaceis tenacibus strictis = 
dichotomis, axillis angustissimis, ramis erectis! fere ap- 
pressis, articulis 4-siphoniis inferioribus diametro 6-8-plo,

Has. New Zealand, Raoul. 
Tufts 4-5 inches long, dense and coarse, dark dull red, 
composed of dichotomous capillary fronds remarkably 
straight and erect. The character attributed to P. stricta 
applies better to this plant than to any specimens of that — 
doubtful species that we have seen. But it would be absurd 
on this account, to refer the present to Dillwyn’s species, - 
which is really very different, and probably only the young of.

ceux-ci.” We have examined M. Montagne's specimen, and whilst we - 
admit the points of difference pointed out by this acute observer, we fear - 
they are not of sufficient importance to warrant our retaining two species; - 
P. byssoclados, of which we have now some hundred specimens, varying - 
considerably in all these respects... >
