1. Barrramia patens, Brid.; caule erecto subramoso, foliis patentibus rigidis linearibus acuminatis 
serrulatis basi dilatatis vaginantibus, theca obliqua, operculo convexo. B. patens, Brid. Bryol. Univ. vol. ii. 
p. 38. Schwaeg. Suppl. vol. i. pt. 2. p. 55. t. 62. B.squarrosa, Turner in Koenig’s Annals of Botany, vol. i.

Haz. Campbell’s Island ; on rocks, half way up the hills; barren. 
Allied to B. ithyphylla, Brid. ; but larger, with the leaves longer and more dilated at the base. 
2. Barrramra robusta, Hook. fil. et Wils.; caule erecto subramoso, foliis patentibus rigidis subulatis 
serrulatis basi quadratis vaginantibus nervo lato continuo, seta crassiuscula, theca erecta, operculo conico 
rostellato. (Tas. LIX. Fig. IV.) 
Has. Lord Auckland's group and Campbell’s Island; in moist places, especially towards the tops of 
‚the hills; barren in the latter island. 
Caules ceespitosi, pollicares, robusti, basi radiculis intertexis fuscis dense obtecti et connexi. Folia densa, rigida, 
subfragilia, nervo latissimo crasso superne supra paginam folii totam extenso, flavo-viridia, inferiora subrufescentia. 
Inflorescentia dioica ; Fl. masc. terminalis ; antheridiis plurimis oblongis, paraphysibus longioribus immixtis. Seta 
8 lin. longa, valida, haud torta, rubra. Theca erecta, globosa, brunnea, siccitate sulcata. Peristomium non visum, 
an nullum?  Operculum conico-rostellatum, luteum. Calyptra fusca. 
A more robust species than the B. patens, with broader and more rigid leaves, their dilated bases truly quad- 
rate. The capsule is perfectly erect, and the operculum rostellate. It essentially differs from the former in the 
dicecious inflorescence. The thecze are not in a fit state to show the peristome, if this moss really possesses one, of 
which we have some doubt. This is not distinguishable from the B. potosica of Montagne (Ann. Sc. Nat., 2nd 
Series, vol. ix. p. 56), judging only from the description of that author; but an examination of authentic specimens 
proves the two truly distinct, the latter being more closely allied to B. patens, though having shorter leaves,with their 
bases not quadrate, but oblong, or almost obovate.

3. Bartramia pendula, Hook.; caule subpinnatim ramoso fastigiato, foliis ovato-lanceolatis longe 
acuminatis-serrulatis striatis nervo continuo, theca pendula ovato-globosa subcylindracea sulcata, operculo 
planiusculo. B. pendula, Hook. Muse. Erot. t. 21. Philonotis pendula, Brid. Bryol. Univ. vol. ii. p. 27. 
Mnium pendulum, Smith in Linn. Trans. vol. vii. p. 262. 
Has. Campbell’s Island; frequent in marshy places, always barren. 
Variable in aspect and sometimes resembling B. fontana. 
19. BRYUM, Dill. 
Peristomium duplex; exterius dentes sedecim, «equidistantes, lanceolati, simplices ; inferius membrana tenera, 
sedecim carinata, in processus totidem dorso carinatos producta, ciliis aut nullis aut plurimis filiformibus interjectis, 
dentibus externis oppositis. Calyptra parvula, cuculliformis. Theca inclinata v. pendula, oblonga, pyriformis v. 
clavata, plerumque annulata, collo brevissimo v. elongato instructa. Caules apices versus innovantes.—Bryum, Webera, 
Pohlia, Cladodium, e£ Ptychostomum, Bridel et auctorum. 
Tn the generic character, given above, we have closely followed that of Bruch and Schimper (Bryol. Europ.), 
though not satisfied of the propriety of excluding Mnium.
