Lepine (Beechey), Viti Levu (Milne! n. 337, Seemann! n. 863). Samoa, Tutuila, on trees; in 
fruit near Lanutoo, the Mountain Lake, Upolu (2500 feet) (Powell! n. 2). 
2. ЇЧ. loriformis, Van den Bosch et Lacoste, Bryol. Javan. t. 183; rami stipitati, superne in 
frondem ramulis paucis inordinatis ramosi; folia in stipite sparsa, ligulata, in medio frondis a basi 
latiora, ligulata, patentia divergentiave, compressa, distichacea, subundulata, fere lævia, nervo fere

rioribus rotundis inferioribus elongatis.—Gau (Milne !), Viti Levu (Seemann ! n. 836), Samoa, Tutuila 
(Powell ! n. 118). 
Foliage less shining than in N. implana, having a rather glaucous appearance. Branches not so rigid, 
more curved, and attenuated. 
XVIII. Porotrichum, Brid. Rami fertiles, inferne simplices stipitiformes, superne in fron- 
dem arbusculosam pinnatim divisi. Folia teretiuscule imbricata vel compressa. Тһеса plus minus

The following species have not yet been found in Viti, viz.:—1. P. elegantissimum, Mitt. Linn. Soc. 
Journ. vol. x. p. 137, from Samoan Islands, Tutuila, on trees near Letaumata and elsewhere (1000 feet) 
(Powell! n. 33). 2. P. mucronatum, Van den Bosch et Lacoste, Bryol. Javan. t. 187, from Samoa, Tutuila, 
on the bark of trees (1000 feet) (Powell! n. 119). 3. Р. Aneitense (sp. nov.), Mitt.; dioieum ? ; stipes 
1-13-uncialis, foliis parvis ovato-lanceolatis patulis sparsis obtectus, superne in frondem horizontalem ramis 
abbreviatis divisus; folia ramea subcompressa, imbricata, ovato-oblonga, obtuse acuta, nervo sub apice 
desinente levi, margine superne crenulata, cellulis omnibus parvis rotundatis areolata—Aneitum (Milne! 
in Herb. Hooker, 369). — Habit that of P. arcuatum, Mitt., of India, but smaller, with shorter and firmer 
leaves; in its size more nearly related to P. pandum, Hook. f. et Wils. Fl. N. Zealand, t. 89. f. 1, but with 
more obtuse leaves, with the nerve not continued to the apex. 
1. P. dendroides, Hook. Musc. Exot. t. 69 (Neckera). Rami elongati, inferne stipite foliis 
imbricatis appressis obtecto, superne in frondem pinnatam vel flabellatam bipinnatamque decompo- 
siti; folia arcte compressa, patentia, oblonga, parum inæquilatera, acuta, subundulata vel levia, 
apice dentata, nervo medio evanescente, cellulis superioribus minutis ovalibus ; folia ramea breviora 
ovalia apiculata, perichzetialia parva apicibus loriformi-acuminatis patulis; theca ovalis, brevi-pedun- 
culata.— Viti (Seemann!). Also in Hawaii (Menzies! Douglas !). 
A large species with flattened foliage. It is allied to P. dendroides, Hornsch. et Reinwardt, from Java 
(Neckera Javanica, C. Müller), and to numerous Indian species, more particularly Р. flabellatum, Sm. 
(Hookeria), in all which the capsule is borne on a very short fruitstalk on the under side of the fronds. 
Trisus VIII. SEMATOPHYLLEÆ.—Fructus in ramulo brevissimo e latere caulis vel ramorum 
oriundo sepius longe pedunculatus. Folia enervia vel rarissime breviter binervia, cellulis basa- 
libus ad angulos paucis oblongis a reliquis sæpe colore diversis.
