7. ORTHOTRICHUM, Hedw. 
Peristomium simplex v. duplex, rarius nullum ; exterius dentes triginta duo, geminatim v. bigeminatim coadu- 
nati, (hine quasi octo v. sedecim apparent); interius cilise octo, sequales, v. sedecim, alternis brevioribus, erectis v. 
horizontaliter patentibus. Calyptra campanulata, costata, basi lacera v. crenata, plerumque pilosa. Theca erecta, 
sequalis, exannulata, tandem sulcata, in setam superne incrassatam gradatim attenuata. 
1. ORTHOTRIOHUM crassifolium, Hook. fil. et Wils.; caule brevi subramoso, foliis erecto-patentibus 
lanceolato-subulatis obtusis carnosis nervo crasso subcontinuo, theca breviter exserta pyriformi levi, peris- 
tomii dentibus sedecim, ciliis nullis, calyptra glabra. (Tas. LVII. Fig. VIII.) 
Var. B; folis longioribus, theca breviore foliis immersa. 
Has. Lord Auckland's group and Campbell's Island; on rocks and stones immediately above high- 
water mark. Var. 8, Campbell's Island, with the following species. 
Caules pulvinati, 2-4 lin. longi. Folia suberecta, crassa, coriacea, supra plana, apice subobtusa, marginibus 
basi inflexis, nervo crasso infra apicem evanido, siccitate paulo incurva, olivacea v. fusco-lutea, demum nigricantia, 
suprema linearia, basi latiora. Inflorescentia dioica? Fl. mase. gemmiformis, terminalis. Seta sub lineam longa, 
valida; vaginula oblonga. Tiheca erecta, pyriformis, v. subturbinata, fusco-lutea, collo brevi, siccitate subeylindracea. 
Peristomii dentes liberi, siccitate erecti v. reflexi, lutei. Spore majuscule, subrotundee, rufo-olivaceze. Operculum 
convexum, rostello recto, thecæ 4 longitud. Calyptra plicata, glabra, rufo-brunnea, basi octofida. 
Perhaps allied to the O. psychrophilum, Montagne (Ann. Sc. Nat., vol. ix. p. 52); but the leaves are more erect 
with their margins not reflexed, the capsule even, of a thicker texture, and there is no inner peristome, It bears 
some resemblance to the O. Magellanicum, Mont., from which the same characters will also distinguish it. The dry 
foliage is of an almost horny consistence.

2. ORTHOTRICHUM angustifolium, Hook. fil. et Wils.; caule brevi subramoso, foliis erectis anguste 
lineari-subulatis acutiusculis carnosis nervo continuo, theca subsessili immersa elliptica, operculo rostellato, 
peristomii simplicis dentibus sedecim. (Tas. LVII. Fig. VII.) 
Has. Campbell’s Island; on rocks at an elevation of 1200-1400 feet. 
Caules pulvinati, 2-3 lin. longi, luridi, rigidi, ramis subterminalibus abbreviatis. Folia suberecta, conferta, 
elongata, stricta, opaca, subcarnosa, supra plana, nervo crasso continuo, siccitate subincurva, atro-viridia; pericha- 
tialia longiora, lanceolata, acuminata, superne attenuata, subsecunda. Seta brevissima. Theca elliptico-ovata, parva, 
pallide fusca, ore majusculo. Dentes conniventes, pallide ferruginei, siccitate reflexi. Spore majuscule. Operculum 
basi convexum, rostello brevi recto. Calyptra non visa. 
Allied to the former species, but with larger, much narrower and almost setaceous leaves; the capsule also is 
smaller and hidden amongst the foliage.

8. MACROMITRIUM, Brid. 
Peristomium simplex v. duplex; exterius dentes sedecim, lanceolati, plus minusve geminatim connexi; interius 
membrana apice lacera, multifida, Calyptra conica, glabra v. pilosa, basi in lacinias plurimas «equilongas fissa. 
Theca equalis, exannulata.
