118 FLOEA ANTAECTICA. [Auckland and 



the perichartial 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 capside 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, monoecious, the male fructification being on separate branches ; 

 though A. 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- 

 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.

 foliis erecto-patentibus incurvis rigidis lanceolato-subulatis acutis v. ovatis longe acuminatis concaviusculis

Hab. Campbell's Island ; on rocks, barren. 



Caules erecti, conferti, ramosissimi, \ una longi et ultra, siccitate rigidi. Folia undique inserta, patentia, deinde 

 incurva, ovata, acmninata, basi gibbosa, enervia, infra medium deuticulata, siccitate subappressa, opaca, rufo-bmnnea, 

 juniora flavo-viridia v. rufescentia, areolis pellucido-punctatis moniliformibus ; perichcetialia submajora, lanceolata, 

 erecta. Flores masculi gemnn'fonnes, foliis ovatis concavis inclusi. Antheridia 4-7, paraj)hysihus filiformibus \ 

 breviora. Fedicellus perichsetimn vix supcrans. Theca parva, nigra, paido exserta. Sporce majusculre, femigineae. 



This species may be distinguished from A. alpina by its narrower and much more acuminated leaves, which are 

 of a paler hue, never shining, gibbous at the base ; those of the perichsetimn do not differ materially from the cauline 

 ones. The specific character and description are drawn up in part from Hermite Island (Cape Horn) specimens ;
