346 FLORA VITIENSIS. 
Vense flabellato-furcate v. a costa media furcatæ, ramis liberis.—Filices caudice herbaceo, plerumque 
repente, frondibus simplicibus pinnatis, pedatis v. supradecompositis. 
The following species have been found in tropical Polynesia, in addition to those described below :— 
1. A. Capillus- Veneris, Linn. Sp. Pl. p. 1096, from the Sandwich Islands (Menzies! Collie! Macrae! M‘Gil- 
livray ! Hillebrand !), and New Caledonia (Vieillard!) 2. A. Bennettii, Carr. in Herb. Mus. Brit. ; stipitibus 
teretibus, ebeneis, nitidis; frondibus ovatis, tripinnatisectis; pinnulis petiolatis, subeoriaceis, supra glabris, 
infra sparse hirsutis, equilateralibus, rotundato-reniformibus basi sinu excisis, v. subcuneatis v. cuneatis, 
antice integris denticulatis; nervis flabellato-dichotomis ; soris oblongo lunulatis.— Sandwich Islands 
(Strickland !). Separated, but not named, from the former species by Mr. J. J. Bennett in Herb. Mus. 
Brit. 3. A. Aneitense, Carr. in Herb. Mus. Brit.; stipitibus semiteretibus, antice canaliculatis, nigris, 
glaberrimis; frondibus amplis, 3—4-pinnatis, rachibus nigris, antice hirsutis, postice glaberrimis; pinnis 
lineari-aeuminatis ; pinnulis glabris, alternis dimidiatis rhomboideo-oblongis obtusis v. in sterilibus subacutis, 
margine superiore et antico lobatis; soris in lobulo sitis, rotundatis, integerrimis, antice sinu excisis.— 
Aneitum (M'Gillivray ! n. 110). This plant is a near ally of the S. American A. polyphyllum, Willd., but 
may easily be distinguished by the hairy rachis and the form of the pinne and pinnules. 
l. A. lunulatum, Burm. Fl. Ind. p. 235 ; stipitibus cespitosis, gracilibus, atro-fuscis, glabris ; 
frondibus oblongis, obtusis, pinnatis; pinnis alternis, petiolatis, lunulato-oblongis, obtusissimis, 
suprema cuneata, margine superiore rotundatis lobatis ; soris linearibus, interruptis, nunc confluenti- 
bus.—Pteris lunulata, Retz. Observ. vol. ii. p. 28. t. 4. A. arcuatum, Sw. Prodr. p. 122.— 
Nomen vernac. Vitiense, teste Storck, “ Kau-ni-vatu."— Viti Levu, Ovalau, and Moturiki (See- 
mann! n. 801, Storck! n. 915). 
2. A, diaphanum, Blume, Enum. Fil. Jav. p. 215 ; stipitibus ciespitosis, ebeneis, nudis; fron- 
dibus pinnatis v. ad basin 1-3-ramosis; pinnulis petiolatis, dimidiato-oblongis, obtusis, margine in- 
feriore integerrimis subdecurvatis, antico et superiore lobatis; venis furcatis, venulis liberis in pinnulis 
sterilibus et inter soros fertilium in dentem obtusum desinentibus ; soris obreniformibus.— 4. setu- 
losum, J. Sm. Bot. Mag. Comp. 1846, p. 22.—Viti (Seemann! n. 808, Harvey !). Also from Aneitum 
M‘Gillivray !). 
9. A. hispidulum, Swartz, Prodr. p. 124 et 321; stipitibus cespitosis, filiformibus, nigris, 
rachique asperis; frondibus pedato-bipinnatis; pinnulis dimidiato-ovato-rhombeis, sterilibus mar- 
gine superiore et antico denticulatis, fertilibus crenulatis, utrinque pilosiusculis, striatis, e nervis 
radiato-dichotomis; soris confertis, subrotundis, indusio hirsuto.— A. pedatum, Forst. Prodr. n. 458 
(non Linn). A. pubescens, Schkuhr, Fil. p. 108. t. 116; Brack. U. S. Expl. Exped. Filices, p. 100. 
— Viti (Seemann ! n. 802, U. S. Expl. Exped.). Also from Aneitum (M*Gillivray !), Tongan Is- 
lands (Nelson !), and Tahiti (Barclay !). 
Var. B. divaricatum, Brack. U. S. Expl. Exped. Filices, p. 100 ; ramis divaricatis; pinnis sub- 
flabellatis, oblongis.— Munia, Viti (U. S. Expl. Exped.). 
4. A. fulvum, Raoul, Choix de Pl. de la Nouv. Zél. p. 9; stipitibus erectis, antice glabris, 
ebeneis, postice hirsutis; frondibus ovato-deltoideis, subpedato-3-4-pinnatis, subhirsutis; pinnis 
lineari-acuminatis, terminali elongata, pinnulis dimidiato-rectangularibus, margine superiore et 
antico sublobato sorifero, inferiore integro; soris rotundato-reniformibus.— Viti (Milne). Also 
from New Caledonia (Vieillard). 
The Polynesian plant referred to this species is probably only a variety of the previous species. 
XIII. Hypolepis, Bernh. Schrad. Neues Journ. Bot. 1806, vol. i. pt. 11. p. 34. Sporangia 
apicibus venarum imposita, in soros suborbiculares ad marginem sinuum laciniarum frondis collecta. 
Indusium suborbiculare, submembranaceum, e margine ortum. Vene simplices vel furcate, e costa 
centrali, venulis liberis. — Filices herbacez, frondibus magnis 2-3-4-pinnatis, rhizomate late 
repente.
