FLORA VITIENSIS. 411 
The following is a non-Vitian species :— M. viridissima (sp. nov.), Mitt. ; caulis elongatus, ramis divari- 
catis pinnatus; folia explanata, ovata, obtusissima, lobulo parvo anguste oblongo integerrimo; amphi- 
gastria ovato-oblonga, obtusa, integerrima.—Samoa (Powell! n. 161).—Caulis 34 uncias longus, ramis 
semiuncialibus latitudine, cum foliis lineam metiens. Folia intense viridia.—A JM. Stangeri foliis magis 
ovatis, amphigastrii forma magis ovata angustis, et lobulo angustiore diversa. 
1. M. Stangeri, Lindenb. et Gottsche, iidem et Nees Syn. Hepat. p. 280 ; caulis elongatus, 
ramis divergentibus pinnatus; folia dorso convexa, orbiculato-oblonga, lobulo late ovali, amphigas- 
trioque oblongo-rotundo, margine recurvo integerrimo ; folia involucralia denticulata, perianthio 
labiis denticulatis.— Viti (Seemann !), Tahiti (Collie in Herb. Mus. Brit.). 
Speeimens all without fruit, but to all appearance not different from the states of this species so 
abundant in New Zealand. | 
VI. Bryopteris, Lindenb.; Gottsche, Lindenb. et Nees Syn. Hepat. 284. Caulis primarius 
repens, radicans, ramos elongatos liberos ramosos ascendentes dependentesve prodens. Folia lobulo 
parvo involuto; amphigastria integra. Fructus e latere ad caulis apicem spectante ramulorum late- 
ralium oriundus. Perianthium plicatum. 
The following species is non-Vitian: —B. vittata (sp. nov.), Mitt.; rami graciles, elongati, ramulis 
breviusculis remotis, pinnatim ramosi; folia patenti-divergentia, ovata, acuta, margine apicem versus 
dentata, basi ventrali subdecurrentia, lobulo minuto suboblongo unidentato inflexo appendiculo parvo 
alæformi carinato, cellulis in folii medio majoribus ovalibus vittam fuscidulam formantibus reliquis rotundis ; 
amphigastria patentia, basi cordato-auriculata, subovata, apice sinu obtuso bidentata, lateribus reflexis 
conniventibus remote breviterque denticulatis.—Samoa (Greffe !), Tutuila (Powell !).—Rami 4-6 uncias 
longi, ramulis uncialibus patentibus, cum foliis lineam lati. Folia fusco-olivacea, вісса arcte inflexa.— 
The speeimens, which are not in a fertile state, are more slender with more remote branchlets than is 
usual in B. Sinclairii or B. striata, but in other respects closely resemble those species, from both of which, 
however, they are immediately distinguished by the leaves. 
* Eubryopteris.—Perianthium dorso planum, ventre unicarinatum. 
1. B. Sinclairii, Mitt. * Bonplandia, 1862, р. 19; rami elongati, pinnati; folia patentia, 
ovato-oblonga, obtusa, apice denticulis paucis brevibus, margine ventrali incurva, lobulo parvo 
involuto in foliis ramulinis unidentato, cellulis parvis oblongis subobscuris; amphigastria oblongo- 
ovalia, apice obtusa, paucidentata, lateribus recurvis; folia involucralia lobulique elongate late lan- 
ceolati, acuti, breviter dentati; amphigastrium ad medium usque in laciniis duabus lanceolatis 
fissum; perianthium dorso planum, ventre unicarinatum, angulis denticulatis.— Viti (Sinclair! 
Seemann ! inter n. 843), Samoa (Powell! n. 152). 
Rami 4—12-unciales, ramulis subuncialibus simplicibus ramulosisve. Folia olivacea, firma, lineam 
longa, sicca inflexa. 
This species differs from Bryopteris filicina, Swartz, so widely distributed in South America, in its more 
elongated fronds, which are more produced at their apices, as if they would be indefinitely continuous. 
** Ptychanthus, Nees ab E. ; Gottsche, Lindenb. et Nees Syn. Hepat. p. 289.— Perianthium 
subcompressum, 8—10-plicatum. 
2. B. striata, Lehm. et Lindenb.; rami elongati, pinnati; folia divergentia, oblongo-ovalia, 
obtusiuscula subacutave, apice denticulata, lobulo minuto ovali involuto; amphigastria rotundata, 
apice retusa, denticulata; folia involucralia minora, acuta; perianthium obovatum, compressum, 
decemplicatum.—Viti (Milne). | 
Rami 8-4 uncias longi, ramis uncialibus, cum foliis lineam lati. Folia olivaceo-fuscescentia. 
These specimens do not appear to differ from those from India.
