Campbell's Islands.] a. Foliis distichis.

1. Hypxtjm lif art uiti, Hook. ; caule erecto subpimiatim rarnoso, foliis remotis erccto-patcutibus distichis lanceolatis margiuatis duplicato-serratis sobdinerviis, theca horizontali ovata, operculo conico acuminato. H. bifariurn, Hook. Muse. Exot. t. 57. Schwaeg. Svppl. t. 257, a. Isothecium, Brid. Bryol. Univ. vol. ii. p. 35G.

Hab. Lord Auckland's group ; ou the dead trunks of trees.

The serratures of the leaves are composed of a double row of spines, as in E. spiniforme. The operculum is half the length of the theca, shorter and less acuminated than in the figure in ' Musci Exotici.'

b. Foliis imbricatis.


 * Foliis solidineniis

2. Hypxuii spiniforme, L.; caule erecto subsimpbei, foliis patentibus lineari-subulatis marginatis duplicato-spinuloso-serratis soliclinerviis, seta subbasilari, theca ovata arcuata, operculo oblique conico rostrato. H. spiniforme, Linn. Sji. PL p. 15S7. Hedwig, Mmc.vol. iii. p. 59. t. 25. Brid. Bryol. Univ. vol. ii. p. 557.

Var. (3, caule gracili, foliis brevioribus lanceolato-subulatis luridis.

Hab. Lord Auckland's group ; var. /3, under large tussacks of grass on the lulls, rare and barren.

Neither in this nor in any other specimens of H. spiniforme have we seen the leaves to be bifarious.

3. Hypxtjm elongat/im, Hook. fil. et Vfils. ; caule elongato robusto subramoso, ramis elongatis, foHis erecto-patentibus ovato-lauceolatis nervo excurrente apiculatis serrulatis striatis. (Tab. LX. Fig. IH.)

Hab. Lord Auckland's group and Campbell's Island ; in dry rocky places on the lulls, rare and always barren.

Caules 4-6 unciales, basi procumbentes, deinde ascendentes, incurvi, parce et vage ramosi. Folia suberecta, dense imbricata, serrulata, phcato-striata, siccitate erecta, subtorta, nervo tenui hi apiculum exsertum suhelongatmn desinente instructa, flavo-viridia, nitida, inferiora sordide viridia, dorso papulosa, areolis minutis oblongis, basi marginibusque pellncidis reticulatis.

This moss closely resembles the H. densum, Swartz (Fl. Ind. Occ), which is but ill represented in Hedwig's 'Species Musconun.'

4. Hypxoi consimile, Hook. fil. et Wils. ; caule elongato subramoso debili, foliis erecto-patentibus supremis secundis ovato-lauceolatis acuminatis serrulatis striatis nervo subexcurrente. (Tab. LX. Fig. IV.)

Hab. Lord Auckland's group ; iu marshy places on the hills, barren.
