FLORA VITIENSIS. | 409 
toothed with teeth which are also themselves dentate, and the perianth is broadly obovate; the lips 
rounded, and with many long teeth. Fragments of this species were mentioned in ‘ Bonplandia’ as 
P. opposita and P. Brauniana. 
II. Jungermannia, Linn. Caulis procumbens, subsimplex. Folia explanata vel sursum 
secunda, integra vel dentata, amphigastria parva vel nulla. Perianthium tubulosum, inferne leve, 
superne plicatum, ore contractum, dentatum. 
The three following species have not yet been discovered in Viti, viz. :—1. J. contracta, Nees ab E.; 
Gottsch. Lindenb. et Nees Syn. Hep. 79.—Samoa (Powell!) 2. J. piligera, Nees ab E. ; Gottsch. Lindenb. 
et Nees Syn. Hepat. 81.—Sandwich Islands, with J. contracta (Hillebrand! Meyen!), Samoa (Powell !).

1. J. flexicaulis, Nees ab E.; Gottsche, Lindenb. et Nees Syn. Hepat. p. 87; caulis procum- 
bens, flexuosus, e ventre proliferus; folia densa, sursum secunda complicataque, cordato-orbiculata 
coneava, apice obtusa vel angulata, margine ventrali inflexo recto, dorsali flexuoso integerrima, 
. cellulis parvis areolata, involucralia integra vel obtuse bi-tridentata; perianthium apice denticulatum. 
— Viti (Seemann !), Sandwich Islands (Tolmie, Herb. Hooker; Hillebrand! n. 9). 
Р ring described from Java, where it is said to be frequent. It is found as far south as New 
ealand. 
ПІ. Chiloscyphus, Corda; Gottsche, Lindenb. et Nees Syn. Hepat. 171. Caulis procum- 
bens. Folia explanata vel sursum secunda; amphigastria bi-quadri-pluridentata. Perianthium in 
ramulo brevi laterale, campanulatum, ore subtruncatum. 
The species comprised in this genus are in habit and general appearance intimately related to Lopho- 
colea, and, as in that genus, they are divisible into a green and a brown group, but in a less well-defined 
manner. 
The following are non-Vitian Polynesian species:—1. C. decurrens (sp. nov.), Mitt.; caulis pro- 
cumbens, elongatus ; folia sursum secunda, opposita, ovata, obtusa, integerrima, margine dorso coalita, 
ventre cum amphigastrio orbiculari dentato confluentia, cellulis rotundis spatiis intercalaribus distinctis 
» areolata ; folia involucralia parva, concava, dentata; perianthium tubulosum, superne plicatum, ore dentato 
ciliatum.—Sandwieh Islands (Nightingale), Samoa (Powell! n. 76). Also in Java and Penang. 2. C. coa- 
litus, Hook.—Aneitum (Milne! n. 874), Isle of Pines (Strange !). 
1. C. confluens, (sp. nov.) Mitt.; caulis procumbens ; folia sursum secunda, opposita, 
subtriangularia, apice sinu parvo rotundato biciliato-dentata vel subintegra, margine dorsali sub- 
recta, undulata, basi connexa, ventrali rotundata, incurva, basi cum amphigastrio magno reniformi- 
rotundato, apice quadridentata, dentibus interioribus longioribus confluente.— Foliis biciliatis, Viti 
(Seemann !) ; foliis apice uni- vel sub-bidentatis, Samoa (Powell !). 
Statura habituque C. decurrenti simillima, sed foliis diversiformibus. 
2. C. Endlicherianus, Nees ab E.; Gottsche, Lindenb. et Nees Syn. Hepat. 184;. caulis pro- 
stratus, elongatus ; folia explanata, oblonga, obtusa, apice integerrima vel denticulis brevibus munita ; 
amphigastria parva, quadrispinosa, uno latere angustissime in folio proximo decurrente; perianthium 
compressum, apice dentatum.—Viti (Seemann !), Norfolk Island (Herb. Hooker), Solomon Islands 
(Milne !), Samoa (Powell! n. 157). 
This species, which is found also in Australia and New Zealand, seems to differ from C. argutus, so 
widely distributed in south-eastern Asia, in its more oblong leaves; in other respects the resemblance is 
very close. The Norfolk Island specimens have a terebinthine odour, whieh is scarcely perceptible in those 
from Samoa. 
IV. Radula, Nees ab E.; Gottsche, Lindenb. et Nees Syn. Hepat. 253. Caulis procumbens,
