zontalia, expansa vel sursum curvata conniventiaque, ovali-rotundata vel apice subangulata ; amphigastria 
lanceolata, profunde bifida, laciniis contiguis; folia involueralia majora, sursum curvata, imbricata, apice 
angustiora dentata, inferne coneava.— Gymnomitrium lutescens, Gottsche; idem, Lindenb. et Nees Syn. 
Hepat. p. 4.—Samoa (Powell, n. 151).— Caulis interdum unciam longus, cum foliis lineam latus. Folia 
pallide albo-viridia, siecitate vix mutata.—There appears to be no difference between these specimens and 
those from India and Java. In this species the fruit appears to arise from the dorsal side of the apex of 
the stem.

vel dentata; amphigastria nulla vel in speciebus paucissimis obvia. Perianthium compressum, lzeve, 
ore truncato vel bilabiato. 
A very extensive genus, of which the species are most abundant in the intertropical regions. They 
are not susceptible of being divided into well-defined sections. The following are Polynesian species not 
vet found in Viti, viz. :—1. P. fissidentoides, Tayl. Lond. Journ. of Bot. 1846; Gottsche, Lindenb. et Nees 
Syn. Hepat. p. 636.—Sandwich Islands (Menzies ).— Compared by Taylor to Р. bursata. Р. Vitiense may 
be the complete state of P. fissidentoides, but it does not suggest any comparison with P. bursata, with 
which Taylor eontrasts it. 2. P. bialata (sp. nov.), Mitt.; rami graciles, subsimplices, infra perianthium 
innovatione singula proliferi; folia remotiuscula, explanata, lata, subovata, obtusa, margine ventrali apiceque 
arce dentata, dorsali integerrima recurva, involucralia majora magis dentata; perianthium late obovatum, 
biis subtruncatis dentatis antice posticeque anguste alatum, ala angusta brevidentata.—Samoa (Powell !). 
—Rami 1-2 uncias alti, eum foliis sesquilineam lati. Folia obscura, fusca. 3. P. pacifica (sp. nov.), Mitt. ; 
rami elongati, superne dichotome divisi ; folia explanata, patentia, dimidiato-cordata, subligulata, obtusa, in 
ramis attenuatis conformia, apice truncato-bidentata, apice margineque ventrali spinoso-dentata, dorsali 
recurva, defitibus parvis remotis inconspicuis.—Sunday Island, ad arbores (Milne! n. 87).—Rami 2-3 
uncias alti, cum foliis latitudine bilineares. 4. P. longispica (sp. nov.), Mitt. ; rami humiles vel elongati, 
apice dichotome divisi; folia explanata, divergentia, semieordato-oblonga, obtusa, in partibus ulterioribus 
tn, margine ubique dentibus parvis spinulosis dentata, dorsali recurva, ventrali basi in auriculam parvam 
tumidam revoluta, involucralia parum diversa ; perianthium obovatum, ala nulla, ore truncato dentato, spice
