ceteris notis supra dictis differre videtur.—Macrae’s specimen with the single capsule, which is not, how- 
ever, very evidently plicate, appears to belong to this species. 
5. M. angulatum, Mitt. Linn. Soc. Journ. 1868, p. 167; rami humiles, graciles, ramosi, laxe cæspitosi ; 
folia patentia pentasticha sicca appressa contorta oblongo-linearia acuta nervo percurrente carinata, mar-

plicato operculo subulato ; calyptra ramentis inferioribus divaricatis pilosa.—Samoa Islands, Tutuila on 
Hibiscus trees (1000 ft.), (Powell! 67).— Very nearly resembling M. orthostichum, Nees ab E., from Java, 
but with leaves not wider at their base, and patent, not squarrose or divarieated. 
** Leiostoma.—Theca ore levi haud plicata. Folia cellulis inferioribus rectis. 
6. M. Tongense, Sull. Amer. Expl. Exp. p. 7. t. 5; rami abbreviati, pusilli; folia densa patentia sicca con- 
torta crispata anguste lanceolato-ligulata obtusa cum apiculo brevissimo nervo percurrente carinata, cellulis 
superioribus parvis rotundis infra folii medium parietibus pellucidis distinctis basilibus angustis elongatis, 
perichætialia conformia ; theca in pedunculo folis perichætialibus breviore oblonga, levis, sieca infra os 
rufum contracta, operculo subulato; peristomium dentibus brevibus pallidis, ealyptra pallida, ad basin 
thecæ descendens, pilis sparsis obtecta.—Tongatabu, Friendly Islands (American Exp.!), Lord Howe's 
Island (M'Gillivray !), Isle of Pines (Strange!). A small species growing in thin matted patches ; it is allied 
to M. involutifolium, Hook. et Grev., from Australia. 
ээж Campylodictyon.— Folia cellulis inferioribus curvatis. Тһеса lævis.—This group consists of а 
considerable number of species, nearly all confined to the Eastern Archipelago. 
7. M. incurvifolium, Hook. et Grev. (Orthotrichum) ; rami elongati, simplices vel ramosi ; folia patentia 
apicibus ineurvis erectis lanceolato-lineali ligulata apiee obtuse acuminata, nervo carinata integerrima, cel- 
lulis superioribus minutis rotundis obscuris inferioribus minus obscuris basilibus oblongis haud lunato- 
curvulis, perichætialia acutiora cæterum caulinis similia; theca in pedunculo brevi globoso-ovata, levis, 
operculo subulato; calyptra pilis brevibus erectis inspersa.— Tahiti (Menzies!), Pacific Islands (Beechey! 
Nightingale !), Piteairn's Island (Beechey !). 
8. M. Powellii, Mitt. Linn. Soc. Journ. 1868, p. 168; rami elongati, in cæspitibus latis aggregati ; folia 
dense inserta a basi brevi erecta recurva divarieata lineali-lanceolata sensim ad apicem acutum angustata 
nervo rufescente subexcurrente carinata integerrima, cellulis basilibus elongatis pellucidis subrectis dimi- 
dium folii longitudinis occupantibus sensim in rotundatas obscuriusculas transeuntibus, perichætialia interna 
breviora lanceolato-subulata pellucida; vaginula pilis paucis brevibus; theca in pedunculo breviusculo, 
parva, ovalis, ore parvo, operculo subulato, peristomio dentibus brevibus pallidis ; calyptra ramentis appressis 
pilosa.—Samoan Islands, Tutuila, on Coeoa-nut trees near the sea-level (Powell! n. 110).—This species 
nearly resembles JM. incurvifolium, but differs in its gradually narrowed acute leaves. 
9. M. Beecheyanum, Mitt. Linn. Soc. Journ. 1868, p. 167 ; rami elongati, ezespitosi; folia dense inserta 
a basi brevi erectiore recurva patentia apicibus incurvis a media sensim subloriformi-angustata, apice ob- 
tusiuscula subacuta, nervo pellucidiore in carina profunde exarata percurrente, integerrima, cellulis inferio- 
ribus eurvatis pellucidis usque ad tertiam partem folii longitudinis productis, inde parvis rotundatis 
obscuriusculis, perichætialia breviora erecta pellucidiora, vaginula ramentis exsertis pilosa; theca in 
pedunculo brevi ovalis, operculo longe subulato, ore parvo state obtuse plicato gymnostoma; calyptra 
ramentosa.—Samoan Islands, Tutuila, on living trees, mostly Hibiscus tiliaceus, 20-500 ft. (Powell! n. 1). 
10. M. glaucum, Mitt. Linn. Soe. Journ. 1868, p. 167; rami elongati, ramulosi, late cæspitosi ; folia 
quinquefaria dense inserta in spiras ad dextram ascendentes disposita elongate lanceolata apice obtusa, 
nervo in mucronem excurrente, dimidio folii inferiore erectiore, superiore recurvo divaricato carinato, apice 
subeucullato-carinata integerrima, cellulis inferioribus pellucidis areuatis ad nervum ultra folii medium 
productis, superioribus minutis rotundatis obscuris, perichætialia plura conformia æquilonga erecta pellucida ;

pallidis ; calyptra ramentis appressis eam longitudine haud excedentibus pilosa.—Samoa Islands, Tutuila, 
forming extensive mats on Breadtruit-trees nearly at the sea-level (Powell ! 109).—Like M. gracile in habit, 
but va leaves having a longer pale base, their apices complicate, so as to appear more acute than they are 
in reality.
