FLORA VITIENSIS. 381 
gymnostoma. Calyptra parva, mitriformis.—A remarkable genus, in its foliage and habit, before the fertile 
prolongations are produced, exactly corresponding with Macromitrium, but in the production of special 
short-leaved shoots, on which the fruit is borne, analogous only to those species of Campylopus, like O. exas- 
peratus, which are referable to the subgenus or group Thysanomitrium. 
1. C. eymosus (sp. nov.), Mitt. ; caulis radicans, foliis sursum curvatis appressis lanceolatis ; rami erecti, 
humiles, in cæspitem congesti, foliis patenti-incurvis ligulatis obtusis, nervo in mucronem excurrente, margine 
basin versus papillis elongatis setiformibus ciliatis, cellulis superioribus rotundis obscuris inferioribus angustis 
p subito in fertilibus, in foliis abbreviatis, quinquefariis imbricatis e basi erecta patenti-recurvis 
ate ovatis obtusis, nervo flavo in mueronem exeurrente, margine basi erenulata mutatis; folia perichætialia 
erecta, oblonga, obtusa, inferne cellulis angustis pellucidis areolata; theca ovata, ore nigro-fusco nitido; 
ramus fructifer infra perichætium innovans, interdum subeymoso-divisus.—lsle of Pines, on stones on the 
main peak (Milne!). Barren branches about two lines high, the fertile prolongations from half to three- 
quarters of an inch high, simple or much divided at the top. The apices of the perichætial leaves are about 
equal with the mouth of the capsule. This appears to differ from the C. apiculatus, Dozy et Molk. Muse. 
Archip. Ind. t. 15, in the following partieulars :—the leaves of the barren shoots, or those of the base of the 
fertile ones, are much narrower, not more than half the width in proportion to their length, and from this 
cause are not imbricated, as represented in the plate at figs. 3 and 4; in the foliage of the fertile pro- 
longations aud the perichætium there appears to be no difference. О. brachiatus, Hook. et Wils. Icon. 
Plant. Rar. t. 746 B. ( Macromitrium), differs in the same respects from C. apiculatus, the leaves being 
very much narrower, and without the ciliiform papillæ at their base. Another specimen sent from 
Kalangan, Borneo, by Motley, differs in habit, and in the foliage of its fertile prolongations being more lax 
and curved. 
Tribus IV. Funarræ.—Peristomium internum, plus minus evolutum, processibus planis vel nullis. 
Calyptra sepe inflata, rostro tubuloso. 
I. FUNARIA, Schreb. Тһеса inequalis, levis vel plicata.  Peristomium externum dentibus 16 obliquis 
apicibus cohærentibus, internum laciniis teneris dentibus oppositis. 
1. F. hygrometrica, Hedw. Fund. vol. i. t. 5. f. 12; caulis brevis ; folia comalia incurvo-imbricata, concava, 
ovali-acuminata, integerrima, nervo brevissime excurrente, cellulis laxis levibus rhombeo-hexagonis areolata ; 
theca in pedunculo elongato humido curvato sicca recto horizontalis, pyriformis, ore magno obliquo deorsum 
spectante, operculo convexo, peristomio completo ; flos masculus in ramo brevi, foliis subserrulatis.—lsle of 
Pines, in burnt places (Milne!). The specimens of this cosmopolite species differ in no particular from the 
usual European state. 
Tribus V. BARTRAMIRE.—7Theca ut plurimum globosa plicataque. Peristomii interni processus carinati, 
per carinam fissi. Folia limitibus cellularum prominulis papillosa. 
I. BARTRAMIA, Hedw. Muse. Frond. Caulis erectus, dichotomus vel ramis infra florem egredientibus 
verticillatim ramosus, Folia pellucida vel obscura. All the Polynesian species yet known belong to the 
natural group which was designated by Bridel PAilonotis; these differ in habit from the group of species 
with thickened dark green foliage, and which are considered .Eubartramie. In Philonotis the stems are 
usually slender, and are branched with a number of equal innovations, arising from just below the inflores- 
cence in a vertieillate manner. The leaves are small and usually nearly pellucid, with narrow nerves, the 
areolation composed of cells which have their upper extremities prominent, and in many species on account 
of this peculiarity, and the margin of the leaf being recurved, their leaves appear more serrate than they 
really are. : 
T В. asperifolia, Mitt. Linn. Soc. Journ. vol. x. p. 185; dioica ; caules humiles, graciles, in cæspites latos 
aggregati; folia patentia ovato-lanceolata, ramea oblongo-lanceolata, omnia neryis dorso superne serratis 
pereurrentibus, marginibus anguste recurvis serrulatis, cellulis pellucidis, superioribus oblongis, inferioribus 
subquadratis, perichætialia longiora a basi latiora subulata serrulata; theca in pedunculo elongato, sub- 
globosa, inzequalis, horizontalis, plicata, opereulo depresse conico; peristomium depressum, internum exter- 
numque dentibus fere levibus; flos masculus parvus, foliis a basi rotundata subulatis erectis.— Samoa, 
Tutuila, on damp earth and on rocks by watercourses, 20-100 ft. (Powell! n. 28). A small pale green spe- 
cies, with stems from a quarter to half an inch high, with small short and rough leaves from the prominence 
of the serrature of the margins and nerves. ; e : 
2. B. obtusifolia (sp. nov.); cæspitosa; caulis crassiusculus, ruber ; folia glauco-viridissima, erecto-patentia, 
incurva, laxe imbricata, ovato-oblonga, obtusa, concava, nervo infra apicem evanido, dorso cellulis prominulis 
subdentato, margine fere ad apicem usque anguste reflexo subcrenulata, apice erecta, cellulis laxissimis 
ovali-hexagonis pellucidis areolata.— Ysabel (Veitch! in Herb. Hooker). A small species with stems, in the 
imperfect state in which it was gathered, about half an inch high; distinct from the Javan В. laxissima, 
C. Mueller, in its obtuse leaves. Another species was gathered in Hawaii by Menzies.
