guisbed from the figure in English Botany of S. fragile (t. 11-4.), S. compressum, Aeh., whence it comes to be a
doubt whether if we consider this, the fruiting, as the ordinary state of the plant, all should not merge into S. com-
press2im, itself a vaiiety of S. corallinum \ against wliich it may be imged that the membranous Tasmanian specimens
also produce fructification abundantly.

Our specimens of this plant are truly magnificent, and this has induced us to add a figure, shelving the globose
appendices (abortive apothecia) which are not represented in the works quoted above. SmaU specimens of this species,
both from New Zealand, Tasmania and the gi*oup now under consideration, so much resemble the S.paschale, as to
be with difficidty discriminated from it, whence we suspect the present plant may prove a remarkably luxmiant
state of that, for it is abundant througbout many warm latitudes, to the exclusion of the S.paschale, which reappears
in the higher latitudes of Cape Horn and Kerguelen’s Land.

immixtis.
A very distinct plant, well characterized by the thick cup into which its plane apothecia are immersed, the
latter in age become much broader, their margins roll back carrying the border of the excipidus inwards, when it
requbes a longitudinal section to shew the true nature of the apothecium.

Acharius cites “ Staten Land ” as the habitat of this species ; we hai'e never seen specimens from the American
Continent (the Cape Horn station quoted in the ‘ Lond. Jomm. of Bot.’ being erroneous), whence it is possible that
the author may refer to another plant ; we have, however, followed our friend Montagne, who gives this name to
his beautifiU plate of our plant.

Except in being of a rather larger size, this docs not differ from a copious suite of specimens which we have
examined from Tasmania. The apothecia are variable, generally the disk flat, but sometimes concave, and in
tbese specimens very much so. In both this and the -S'. Billardieri, which seems hardly distmct from it, the border
of tbe apothecia is often evanescent.
