FLORA VITIENSIS. 383 
Kermandec Islands (M'Gillivray !) ; Samoa, Tutuila (Powell!).— Compared by the author to В. pallens, Sw., 
and B. turbinatum, Hedw., and described as from 1-2 inches high, but the figure represents it from half an 
inch to an inch high. The specimens from the Kermandec Islands are shorter even than this, but corre- 
spond very well in the form of the leaves. It seems to be a small species allied to the European B, erythro- 
carpum, Schw., and the B. chrysoneuron, C. Miiller, so frequent in New Zealand. 
4. B. Billardierii, Schw. t. 76; “ саше mediocri bifido, foliis oblongis oblique cuspidatis immarginatis 
dentatis, theca pendula ineurva."—New Belgium (Labillardière !) ; Lord Howe's Island (Milne !).—* Caulis 
rimarius semiuncialis, pone florem ramos aliquot simplices edens, semiunciales aut unciales; folia densa et 
in rosulam congesta in саше primario et ad apices ramorum, sparsa in inferiore ramorum раме; folia con- 
eava, carinata, patula, oblonga, apice dentata, sæpe obliqua, absque margine notabili, siecitate undulata et 
paululum complicata, amæne viridia; nervus crassus, ferrugineus, ex apice folii emergit absque comitante 
parenehymate et recurvatur, quindecies ibi brevior est quam folium ; areolæ reticuli e rhomboide sub- 
rotundi; seta sesquiuncialis aut biuncialis, apice ad horizontem curvata; theca oblonga, incurva, et per 
curvaturam suam pendula, ore vix contracta, ut seta operculum et peristomium externum e fusco brunnea ; 
operculum plano-convexum, mucronulatum.”—The specimens collected by Milne consist of only a few 
ineomplete stems, but seem to agree with the figure and the above description given by Schwægrichen. 
It is probable that the B. rufescens, Hook. f. et Wils. Fl. Tasmanica, p. 192. t. 174. f. 1, belongs to this 
species, for it corresponds with the description and figure in the form ud margin of its leaves, as well as in 
the nerve being exeurrent into a terete point. 
5. B. leptothecium, Tayl. in Phytologist, 1844, p. 1094; caulis gracilis; folia in rosulis congesta, 
patentia, oblongo-obovata vel spathulata, nervo apice cum limbo marginali coalito in mueronem brevem 
recurvum producto; cellulis superioribus oblongo-hexagonis, utriculo contracto repletis, limitibus angustis 
marginalibus angustis in seriebus pluribus congestis limbum tenerum denticulatum sistentibus; theca in 
peduneulo elongato sporangio cylindraceo subrecto, collo sensim angustato curvato pendula, operculo 
depresso-conico.—Society Islands, barren (Bidwill! in Herb. Hooker).—Stems nearly an inch high, and 
to all appearance not different from the states so frequent in Australia and Tasmania. 
6. B. Commersoni, Brid. Mant. p. 119; Sehw. t. 80; caulis plus minus elongatus, laxe cæspitosus; 
folia ubique per caulis longitudinem æqualia vel in rosulis congesta patula obovato-spathulata acuminata, 
nervo breviter excurrente mucronata margine inferne integerrima e medio usque ad apicem denticulis 
brevibus serrata, cellulis hexagono-ovalibus ehlorophyllosis, parietibus mollibus, marginalibus longioribus 
limbum indistinetum formantibus, perichætialia interna minora; theca in pedunculo elongato horizontalis, 
elongato-cylindracea, arcuata, opereulo conico acuto.—Lord Howe’s Island, low ground abundant, but 
barren (Milne ! Herb. Hooker, 47).— Specimens small and short, but agreeing in the dull, dark green colour 
of the younger and pale fulvous tint of the older leaves, as well as in the areolation and margin with 
B. Beyrichianum, Hornsch., and B. umbraculum, Burchell, Hook. Muse. Exot. t. 133, between all which 
the correspondence is so close as to lead to the supposition they may be states of only one widely spread 
species. 
III. CRYPToPODIvM, Brid. vol. ii. p. 30. Caulis erectus. Folia undique æqualia, angusta, e cellulis 
parvis firmis areolata. Тһеса in pedunculo brevi levis. Peristomium completum. 
1. C. Bartramioides, Hook. Muse. Exot. t. 18 (Brywm); caulis simplex vel innovationibus ramosus; 
folia inferiora parva appressa sensim superne longitudine inerescentia, superiora patentia vel subsecunda a 
basi suboblonga sensim subulato-angustata rigida setacea, nervo marginibusque supra basin oblongam usque 
ad apicem dentibus brevibus geminatis serratis, cellulis firmis rotundis parvis inferioribus suboblongis, peri- 
chætialia a basi latiora lanceolata subulata caulinis similia thecam ovalem inclinatam longe superantia ; 
peduneulus vix theca longior; peristomium dentibus lineali-subulatis firmis, internum processibus cari- 
natis parce pertusis, ciliisque tribus æquilongis interpositis in membrana usque ad dentium medium exserta 
impositis.—Sandwich Islands (Gaudichaud !) —A remarkable Moss, having the rigid stems and foliage of 
Rhizogonium spiniforme, but with its fruit terminal, and not exserted beyond the leaves. It is not allied to 
Bartramia. 
tt Folia tristicha, dimorpha. 
IV. Catomnton, Hook. f. et Wils. Theca erecta, gymnostoma. 
1. O. denticulatum, Mitt. Linn. Soc. Journ. vol. x. p. 192; folia lateralia omnia superficiebus superioribus 
ad idem latus spectantia, patentia, oblonga, nervo in mucronem excurrente, margine a medio ad apicem 
usque denticulata; folia media appressa, dimidio breviora, suborbiculata, superne dentata; folia omnia 
cellulis parvis rotundatis interstitiisque pellucidis firmis, perichætialia longiora spathulata lineari-lanceo- 
lataque; theca in peduneulo gracili, ovalis, erecta, operculo subulato. Planta maseula flore apicali gemmi- 
formi.—Samoa, Upolu, on trees (Powell! n. 103).— Corresponding in size, habit, and appearance with 
C. letum, Hook. f. et Wils. Fl. New Zealand, pl. 87. f. 5, but with denticulate leaves, and the capsule appears 
to have a smaller mouth. The stem is said in the ‘Handbook of the Flora of New Zealand’ to be creeping, 
but this is not observable in the specimens of the Samoan species. | å |
