6 CRYPTOGAMIA ANTARCTICA, [Auckland and 
the pericheetial leaves, whilst the true pedicel or seta remains wholly included in the vaginula. The calyptra hence 
continues attached to the vaginula for a much longer period than in other genera, and its rupture is occasioned by 
the distension of the theca ; and not by an elongation of the seta. If a very young capsule be longitudinally divided, 
the seminal sac will be seen lining its interior, and also extending over the surface of the columella, the apex of the 
latter being attached to the summit of the operculum. The sporules, in a very early stage, are aggregated in fours, 
and long before the bursting of the calyptra attain a deep brown colour. 
The inflorescence is usually, and perhaps invariably, moncecious, the male fructification being on separate branches ; 
though 4. mutabilis (nobis) appears really dicecious. Both kinds of flowers are, at first, truly terminal, though, owing 
to the rapid growth of innovations, especially on the male surculi, they soon become, to all appearance, lateral and 
even axillary. The male flowers, from their small size, are, in general, concealed by the cauline leaves. The anthe- * 
8 y 
ridia vary in number, from one or two to seven, intermixed with paraphyses, which, however, have not been seen in 
A, mutabilis (nobis), and which that species probably wants. In the female flower the archegonia are generally four, 
never more, and are not accompanied with any paraphyses.

Has. Campbell’s Island; on rocks, barren.

This species may be distinguished from 4. alpina by its narrower and much more acuminated leaves, which are 
of a paler hue, never shining, gibbous at the base; those of the perichzetium do not differ materially from the cauline 
ones, The specific character and description are drawn up in part from Hermite Island (Cape Horn) specimens;
