erectis, glabris; frondibus membranaceis, ovatis, acuminatis, pinnatis; pinnis distantibus, ovato- v 
oblongo-acuminatis, pinnatifidis ; laciniis oblongis, utrinque grosse dentatis ; soris in dente obsolete im- 
mersis; indusio cylindrico, parumper ventricoso, ore bilabiato.— Viti (Seemann! n. 782, Milne 
and M‘Gillivray !). 
15. T. (Cephalomanes) Australicum, V. d. Bosch, Nederl. Kruidkund. Archief, 1860, p. 139 ; 
rhizomate brevissimo ; stipitibus teretiusculis, basi hirsutis ; frondibus oblongo-linearibus, acuminatis, 
pinnatis; pinnis subsessilibus, e basi acute cuneata oblongis, obtusis; margine superiore dentato, in- 
feriore acute v. setaceo-dentato; venis pinnatis, furcatis; soris in margine superiore pinnarum api- 
calium seriatis, amplis, basi immersis; indusio cylindrico, breviter ventricoso, in limbum amplum 
dilatato.—C. Wilkesii, V. d. Bosch, l.c. p. 140. T. Javanicum, Auct.—Viti Levu (Seemann; n. 
769, Harvey! Græffe!). Also from Aneitum (M‘Gillivray !) 
The dilated mouth of the indusium at once distinguishes this plant foa T. Javanicum, with which it 
has been confounded. 
16. T. polyanthos, Hook. Sp. Fil. vol. i. p. 138; stipitibus ceespitosis, subrobustis, scabris, 
subhispidis; frondibus oblongis v. ovato-lanceolatis, pinnatis; pinnis lanceolatis, bi-tripinnatifidis, 
segmentis lineari-obtusis; soris in laciniis ultimis axillaribus, exsertis, copiosis, magnis, campanu- 
latis, bilabiatis, labiis integris obtusis v. truncatis, patentibus, receptaculis inclusis.— Viti, terrestrial 
(U. S. Expl. Exped.). 
|... 17. T. exaltatum, Brack. U. S. Expl. Exped. Filices, p. 259; rhizomate czspitoso; stipitibus 
rachibusque teretibus, rufo-pilosis ; frondibus rigidis, erectis, ovato- v. oblongo-lanceolatis, bipinnatis ; 
pinnis elongato-lanceolatis, inferioribus remotis patentibus, superioribus approximatis erecto-patenti- 
bus ; pinnis secundariis pinnatifidis v. bipinnatifidis ; laciniis linearibus, obtusis ; soris supra-axillaribus 
turbinatis, exsertis, ore integerrimo ; receptaculo clavato, vix exserto.— Viti (Seemann ! n. 781, Milne ! 
U. S. Expl. Exped.). Also from mountain woods, Aneitum (M‘Gillivray !). 
This is a larger and more robust plant than P. apiifolium, Presl, with broader, blunter segments and 
shorter indusium. It has a broader frond, and a longer and stouter stipes, than T. polyanthus, with an 
entire mouth to its turbinate indusium.

angustis erectis; segmentis linearibus, angustissime membranaceis; soris subexsertis, indusio cylin- 
drico, limbo reflexo leviter undulato ; receptaculo exserto.— T. maximum, var. 8, Blume, Enum. Fil.
