боза; caulis humilis; folia patentia, a basi brevi contracta ovali-oblonga, apice obtuse acuta, nervo percur- 
rente, margine apice crenulato integerrimove, ad latera folii inflexo ; cellulis superioribus minutis rotundatis 
viridibus, basilibus paucis oblongis pellucidis majoribus.—Samoa, Tutuila, on trees (Powell! 123).—More 
robust than W. ( Hyophila) Javanica, Nees et Blume, the leaves not so acute, and at their apices more or 
less distinctly erenulate. 
II. ENCALYPTA, Schreb. Gen. Pl. n. 1643. Calyptra magna, cylindracea, inflata, rostrata. 
1. E. Sandwichensis, Sull. Amer. Expl. Exped. 1859, p. 6; “monoica; foliis oblongo-lanceolatis et 
elongato-spathulatis convolutis papillosis evanido-costatis; capsula gymnostoma, eylindracea, sieca 8-10- 
sulcata; calyptra tota superficie papillosa; flore masculo monophyllo."— Hawaii, sides of Mauna Kea; East 
Maui, banks of the Crater (Amer. eus !).— Densely cæspitose, 1 inch high, radiculose; leaves soft, mar- 
gins crenulate, upper cells hexagonal-rotund. Capsule slightly apophysate. 
Tribus ПТ. ORTHoTRICHIEE.—Caules erecti, apice fertiles vel repentes ex apicibus ramorum fructiferi. Folia 
viridia, obscura, cellulis inferioribus parum diversis vel elongatis. Peristomium simplex vel duplex, 
interdum nullum ; dentibus latis cum processibus internis alternantibus. 
I. MACROMITRIUM, Brid. vol. i. p. 306. Caulis repens, ex apicibus ramorum fertilis. Theca levis plicatave. 
Peristomium externum dentibus discretis geminatisve, internum processibus totidem, dentibus similibus 
vel in membranam truncatam coalitis, вере autem simplex, vel omnino deest. Calyptra campanulata 
plicata, basi plurifida.—A very extensive genus of tropical and austral species, all conspicuous for their 
lobed calyptras. 
* Goniostoma.—Rami simplices vel fasciculatim ramosi. Folia cellulis inferioribus rectis. Тһеса 
ore intensius colorato subearnoso. 
Pedunculus abbreviatus. 
1. M. brevisetum (sp. nov.), Mitt.; pusillum; rami breves, erecti, simplices; folia patentia lanceolato- 
ligulata obtusa nervo in mucronem brevissimum excurrente carinata, margine apicem versus minute crenu- 
lato, cellulis superioribus rotundis obseuris, basilibus paucis oblongis, perichætialia longiora, apice in 
mucronem piliferum acuminata; theca in pedunculo eam breviore emergens oblongo-ovalis, ad medium 
usque plicata, operculo subulato; calyptra ramentis sparsis pilosa.—Oahu (Beechey !).—In its short fruit- 
stalk, this species differs from all that have yet been described. 
Pedunculus elongatus. 
2. M. prorepens, Hook. Muse. Exot. t. 120 (Orthotrichum) ; rami breves, graciles, fasciculatim ramosi, in 
cæspitem congesti; folia erecto-patentia sicca arcte imbricato-contorta lanceolato-ligulata apice obtuse acuta 
vel brevissime acuminata margine uno latere reflexo integerrima nervo percurrente superne carinata inferne 
in plica subcomplicata sepulto, cellulis in dimidio folii inferiore erectiore elongatis, papillis grossis, in dimidio 
superiore minutis rotundis obscuris papillis minoribus, perichætialia interna brevia ovata obtusa; theca in 
pedunculo brevi ovalis, ore plicata, calyptra ramentis appressis pilosa.—Norfolk Island (F. Bauer !), also in 
New Zealand. This small species appears to be less frequently sent from New Zealand than some of the 
nearly allied ones, none of which, however, have their leaves in the dry state so closely contorted. 
3. M. piliferum, Schw. t. 172; rami erecti, humiles, fasciculatim ramosi; folia a basi brevi erectiore 
patenti-incurva sicca contorta anguste lanceolata lineali-attenuata apice obtusa pilo fulvo terminata nervo 
percurrente carinata integerrima, cellulis superioribus densis opacis inferioribus pellucidioribus inter se 
remotiusculis rotundis basilibus paucis oblongis, perichætialia longiora exserta erecto-patentia lanceolato- 
subulata attenuata ; theca in pedunculo breviusculo oblongo-ovalis, fere ad basin usque plicata, fusca, opereulo 
subulato ; calyptra ramentis pallide flavis erectis dense vestita—Sandwich Islands (Douglas! Menzies ! 
Beechey !). The hair-pointed leaf, so obvious in this species, is of rare occurrence in the genus. : 
4. M. Owahiense, C. Mueller, Bot. Zeit. 1864, р. 359; monoicum, late intertexte cæspitosum, humile, 
gracillimum, longe prorepens, ramulis pinnatim dispositis brevissimis gracillimis sterilibus sensim minoribus 
instructum, inde in stolonem elongatum radicantem secundifolium protractum ; ramuli fertiles ante stolonem 
illum egredientes, breves, apice fastigiatim divisi, virentes, dein lutei vel sordide fuscescentes, madore haud 
turgescentes sed graciles; folia crispatula humore erecto-patula apice incurva multo minora angustiora

ferrugineum parum latius concava, margine erecto deplanato vel reflexo integerrima, e cellulis levibus 
diaphanis apice quadratis mox longioribus pariter incrassatis basi elongatis luteis vel aureis areolata, peri-
