FLORA VITIENSIS. 385 
peristomii dentes bifidi. Calyptra parva, dimidiata, vel basi subintegra.—Å very extensive genus of mostly 
small and very elegant Mosses, remarkable for the peculiar structure of their leaves, in which the true leaf— 
lamina vera—is considered to be that part. which embraces the stem, and out of the axil of which the in- 
florescence arises ; but beyond the apex of this, and along its keel the leaf is so expanded that when the 
stems are viewed laterally, the whole leaf appears as if flat, and inserted vertically upon the stem.

circiter 10-juga, patentia, oblongo-linearia, acuta, nervo pellucido percursa, lamina vera usque ad medium

constricta sublageniformi; peristomium dentibus teneris luteis brevibus irregularibus.—Samoa Islands, Tu- 
tuila, on Cyathea leucolepis, Mett., 1000-2000 ft. (Powell! 22).—The entire plant is about three lines high. 
From F. scabrisetus this species differs, in its less obscure leaves, and in the elongated capsule. 
2. Е. inconspicuus, Mitt. 1. с. p. 185; monoieus; pusillus; folia circiter 6-juga, patentia, lineari-lanceo- 
lata, acuminata, nervo pellucido percurrente, lamina vera usque ad medium producta subæquali, omnibus 
laminarum marginibus crenulatis, limbo carente, cellulis minutis rotundis pallidis obscuris papillosis; theca 
in pedunculo breviuseulo, parva, obovata, inclinata, opereulo subulato.—Samoa, Tutuila and Upolu, on 
Cyathea leucolepis, 1000-2000 ft. (Powell! n. 121).—Stems with the leaves about a line high. Pale green or 
rusty brown. Seta half as long again as the leaves. 
8. Е. scabrisetus, Mitt. 1.с.; monoicus; caulis elongatus; folia circiter 12-juga, patentia, approximata, 
elliptico-lanceolata, nervo angusto pellucido percurrente, lamina vera ad medium usque producta subæquali, 
a basi usque ad medium hyalino-limbata, lamina dorsali basi rotundata, marginibus ubique tenuissime 
crenulatis, cellulis minutis obscuris viridibus minutissime papillosis ; theca in pedunculo brevi aspero, ovalis, 
inclinata, operculo subulato obliquo; flos masculus in axillis foliorum superiorum.— Samoa Islands, Tutuila 
(Powell! n. 63).—Stems about 4 lines high, and with the leaves about 1 line wide. The seta is about a line 
or a line and a half long. The capsule with vesicular cells and a red mouth. 
4. Е. abbreviatus (sp. nov.), Mitt. ; monoicus; caulis brevis, semilinearis; folia 4-8-juga, approximata, 
patentia, elliptico-lanceolata, acuta, nervo pellucidiore percursa, lamina vera usque ad medium producta apice 
subæqualis usque ad medium ejus longitudinis tenui hyalino-limbata, lamina dorsali basi decurrente api- 
calique subintegerrima, cellulis minutis obscuris levibus; theca in peduneulo brevi pallido, ovalis, erecta, 
opereulo subulato obliquo; peristomium dentibus rubris. Flos masculus vel terminalis vel in ramulo 
brevissimo basilaris.— Raoul Island (M‘Gillivray! in Herb. Hooker). A minute species, different from any 
of the preceding. 
Твівгв I. DICRANEZE.— Folia viridia, вере elongata, angusta, nitida, nervo sepe dilatato, cellulis 
basilaribus ad angulos sepe majoribus coloratis. Peristomii dentes integri vel furcati.
