FLORA VITIENSIS. 395 
calyptra ad medium operculi descendens, pilosa, basi integra.— Viti (Amer. Expl. Exped.), abundant 
on trees in the mountains (Milne! in Herb. Hooker) ; Samoa, Tutuila, on Cocoa-nut, Hibiscus, and 
other trees, 1000-2000 ft. (Powell! n. 7). 
Primary stem tough, creeping over the bark and branches of trees, when old leafless, from this arise 
numerous erect or ascending branches from 2 to 4 inches high, usually undivided for the space of half or 
three-quarters of an inch, above this they are regularly pinnate with the length of the branches deereasing 
towards their apices, or they are more or less closely set with irregular long and short branches in a suffru- 
ticose manner; a few stems have been seen which appear to have grown procumbent, and are somewhat 
elongated, but these do not show a tendency to become pendulous. 
XIV. Meteorium, Brid. Rami fertiles breviusculi, simplices vel pinnatim ramosi, e caule 
repente vel libero pendulo prolixe continuato oriundi. Folia undique æqualia vel subcompressa ; 
theca immersa vel exserta. Peristomium perfectum vel sæpius internum ciliis carens. Calyptra 
plurifida vel dimidiata. 
The following species have not yet been found in Viti, viz.:—1. M. æruginosum, Mitt. Linn. Soc. 
Journ. vol. x. p. 171. t. 5 B.—Samoa, Upolu, on trees (1000-2000 ft.), (Powell! n. 88). 2. M. (Eumeteo- 
rium) vuleanicum, (sp. nov.) Mitt.; rami ramulis curvatis pinnatim ramosi; folia laxe imbricata, oblonga, 
obtusissima, excavata, apiculo parvo angusto terminata, margine superne involuta, basi subcordata, cellulis 
ad angulos in maculam fuscam condensatis, superioribus angustis brevibus, ramulina conformia apiculo 
breviore.— Hawaii ad montem ignivomem (Macrae! in Herb. Musei Brit.).—In size and appearance nearly 
resembling M. molle, Hedw., but more rigid, and with its leaves tipped with an apiculus. 3. M. trichopho- 
rum, Mont. Ann. des Sc. Nat. 1843, vol. xix. p. 238 (Isothecium ?) ; б Mueller, Syn. vol. ii. р. 130 (.Neckera). 
—Sandwich Islands, on the bark of trees (Gaudichaud!). 4. M. Hornschuchii, Mitt. Linn. Soc. Journ. 
1859 (Trachypus).—Sunday Island, trees on the summit of the mountains (Milne! n. 90), Kermandec 
Islands, Raoul Island (M'Gillivray !), Pacific Islands (Beechey !). 5. M. helictophyllum, Mont. Voy. au Póle 
Sud (Cryphea).—Tahiti (Lesson, Jaquinot), Pacific Islands (Beechey !) 6. år lanosum, Mitt. Journ. of 
the Proceed. Linn. Soc. 1859 (M. longissimum, Dozy et Molk. Bryol. Javan. t. 202).—Pacific Islands 
(Beechey), Samoa, Tutuila, on trees in a damp place (1000-1500 ft.) (Powell, n. 4). 7. M. (Ærobryum) 
striatulum (sp. nov.), Mitt. ; rami elongati, flexuosi, ramulis divergentibus pinnati; folia compressa, late 
ovato-lanceolata, acuminata, serrulata, nervo angustissimo medio evanido, cellulis angustis papillosis areolata, 
humida lævia, sicca longitudinaliter quater plieata.— A neitum, in damp places (Milne!), South Sea Islands 
(Nightingale !).—Stems a foot or more long, slender, soft; foliage more close than in A. lanosum, and less 
glossy, ochraceous. Very similar to A. lanosum, but with a different appearance from the folds in the leaf 
when dry. 
l. M. intricatum, Mitt. Linn. Soc. Journ. vol x. p. 171. t. 5 A; dioicum; rami graciles, 
elongati, flexuosi, ramulis divergentibus curvatis laxe pinnatim ramosi; folia ramea undique erecto- 
patentia, torta, a basi cordata, auriculis crenatis, ovato-lanceolata, sensim acuminata, integerrima, 
nervo obsoleto, cellulis angustis elongatis brevissime obscureque pluripapillatis; folia ramulina 
superne latiora, haud acuminata, subserrulata, semitorta, medio inferne canaliculata, nervo tenui infra 
medium obsoleto; folia perichztialia patentia, longe acuminata; vaginula filis exsertis barbata; 
pedunculus crassiusculus, sublævis, foliis perichætialibus subduplo longior, eurvatus; theca oblongo- 
cylindracea, inzequalis, operculo subulato; peristomium dentibus elongatis irregularibus nonnullis 
inter se cohærentibus fissisve obscuris, internum processibus angustis obscuris brevioribus, membrana 
basilari carens ; calyptra inferne pilis paucis barbata. Flos masculus parvus, antheridia 8-10 paraphy- 
sibus paucis immixta fovens.—Viti (Seemann!). Also in Samoa, Tutuila, on living trees in the 
shady forests (20-1000 ft.) (Powell! n. 5). 
Foliage green, dark brown in age. In size, colour, and habit, this species — with M. helectophyl- 
lum ; but its longer capsule is exserted, and thus it comes nearer to M. floribun Dozy et Molk. Musc. 
Archip. Ind. t. 53, but from this it differs in the cordate-auriculate base of its leaves, and also in the teeth 
of the external peristome not being united on a base that is exserted above the mouth of the capsule. 
2. M. Vitianum, Sull. Amer. Expl. Exped. t. 21; majusculum, caulibus longissimis pendulis
