404 FLORA VITIENSIS. 
cellulis angustioribus viridibus formatis. Fructus ex apice rami proprii e centro fasciculorum 
oriundus. Theca sessilis, globosa, demum in prolongatione rami fertilis pedunculiformi exserta, 
opereulo convexo; calyptra tenuissima, medio transversim rupta parte infericre vaginula ad- 
hærente obvelata. Flores masculi antheridiis globosis pedicellatis in axillis foliorum, ad apices 
ramorum amentiformes congesti. Genus unicum :— 
XXVII. Sphagnum, Dill Caulis erectus, fastigiato-ramosus, ramis flagelliformibus. Folia 
caulina pentasticha, ramulina diversiformia densius texta, omnia ecostata, Fructus e ramulis oriun- 
dus. Тһеса globosa, solida, operculo hemisphærico, annulo peristomioque destituta. 
S. acutifolium, Ehrh., has been found at St. Paul's Island, on the summit of the mountain (Milne! n. 
22). 
1. S. cuspidatum, Ehrh.; caulis plus minus elongatus, fasciculis ramorum remotiusculis, cor- 
tice distincto nullo; folia caulina ovata acuta, limbo indistincto, ramea imbricata ovato-lanceolata 
limbo lato marginata, cellulis majoribus fibro repletis; folia in ramo fertili oblonga ovaliave, cellulis 
majoribus inanibus.— Viti (Seemann ! n. 839). 
This species is easily recognized from most of its eongeners by the absence of any distinet pellucid 
cortical cells. The Vitian specimens are without fruit, but have all the appearances of being precisely the 
same as European.

The following genera have not as yet been found in Viti, viz. :— 
I. Coxoscyruus, Mitt. gen. nov. Caulis procumbens ascendensve, ramosus. Folia sursum secunda, 
integra paucidentatave. Amphigastria magna. Perianthium proprium nullum, e foliis involucralibus in 
conum convolutis apice dentibus paucis inflexis formatum. 
1. С. inflexifolius, (sp. n.) Mitt. ; caulis procumbens, elongatus, parum divisus; folia antice inflexa, 
subovata, obtusa, margine dorsali sinuata integerrima, ventrali convexa, caulem versus bidentata, amphi- 
gastria magna rotunda, apice bidentata, lateribus tridenticulatis ; folia involueralia teretiuscule imbricata.— 
Samoa, inter cæspites Syrrhopodontis crocei, Sendtneræ juniperinæque, sparsim crescens (Powell !).—Rami 2 
uncias longi, cum foliis lineam lati. Folia castaneo-fusca, imbricata.— Similar in habit, colour, and appear- 
ance to Lophocolea devexa, Mitt. Journ. of the Linn. Soc. vol. vii. p. 165, and to the Chiloscyphus trapezoides 
and С. Tjiwideensis, Van der Sande Lacoste, Hep. Javan. t. 7, all probably belong to the same genus. 
The Samoan specimens have the inner involueral leaves convolute, so as to form a flask-like perianth, but 
they do not appear to be anywhere combined with each other or with the stipule; at their bases they are 
adherent to the lower part of the calyptra. In C. devexus the involucral leaves are arranged in a similar 
manner; but as only young states of the fructification were present, it was supposed that the species was 
allied to some austral South American species of Lophocolea, as L. Gayana (Chiloscyphus), Mont., the 
fructification being evidently terminal, but supposed to be incomplete. The occurrence, however, of the 
same kind of involuere with young capsules leaves no doubt but that a true and tubular perianth is want- 
ing in both the Afriean and Samoan species. The place of this genus is somewhat obseure. In habit, and 
in the substance of its leaves and its conspicuous stipules, it corresponds most nearly with some species of 
Lophocolea and of Leioscyphus.

dentato-ciliatis.— Samoa (Powell )).— Caulis unciam longus, cum foliis lineam latus. Folia pallida, tenera. 
4. L. rectangulata (sp. nov.), Mitt.; caulis procumbens, elongatus ; folia explanata, plana, oblonga, sub-
