1. Acrostichum splendens. Willd. Sp. PL v. 5. p. 104. Gaud, in Freyc. Voy. v. \. jj. 303. 
(non Kaulf.) 
This is assuredly the plant of Gaudichaud, and agrees with Willdenow’s description ; but Kaulfuss must 
have some other species in view when he describes the fronds as on both sides “ stellato-squamoscBP 
1. Polypodium atro-punctatum ; frondibus sparsis lineari-lanceolatis elongatis acuminatis 
basi attenuatis utrinque glabris supra squamosis aut atro-punctatis margine subundulatis, 
soris solitariis rotundato-oblongis subimmersis junioribus squamuloso-tectis. Gaud, in Freyc. 
Voy. V. \. p. 346. — Pleopeltis elongata. Kaulf. Fnum. Fil. p. 346, (certe.) 
Gaudichaud has accm’ately described this species, and we think it equally certain that it is the Pleopeltis 
elongata of Kaulfuss ; but, in our specimen, the scales on the underside of the frond, and of the fructifi- 
cation, ai’e quite obliterated, and indeed are described as so very fugacious, that we pi’efer arranging the plant 
with the Polypodia rather than with the Pleopeltides. 
2. Polypodium setigerum; fronde simplici lineari-lanceolata brevissime stipitata utrin- 
que margineque pilis rigidis sparsis atro-purpureis, soris biserialibus approximatis rotun- 
datis setosis. (Tab. XXI. A.) 
Radix caespitosa, fibrosa. Stipites 5-6 ex eadem radice, brevissimse. Frondes vix digitales, liueari-lan- 
ceolatse, subcoriaceae, obtusae, flavo-virides, costa obscura, basi attenuatae, utrinque margineque pilis rigidis sen 
setis atro-purpiu’eis patentibus sparsis obsitae, margine piano. Sori in parte sxiperiore frondis numerosi, 
approximati, orbiculati, intense fusci. Capsulce setis immixtae.

3. Polypodium Pseudo-grammitis ; frondibus sparsis linearibus basi longissime attenuatis 
margine subundulato-crenulatis utrinque glabris, soris rotundato-oblongis sparsis rarissimis, 
stipite marginato, caudice capillari paleaceo radicante, squamis lanceolatis, radicibus villosis. 
(Tab. XXL B.) — Gaud, in Freyc. Voy.p.'B^b. — Grammitis tenella. Kaidf. Fnum. Fil. 
p. 84. 
The fronds of this are very tender and membranaceous, 1-6 inches long, sometimes unequally forked to- 
wards the extremity.

4. Polypodium spectrum; caudice longe repente, frondibus simplicibus bastato-cordatis 
3-5-lobatis latissimis membranaceis acutissimis reticulatis, soris sparsis, stipite glabro. 
Kaulf. Fnum. Fil. p. 94. — P. Tbouinianum. Gaud, in Freyc. Voy. p. 348. t. b. f. \. 
Fronds 6-8 inches in diameter. This remarkable plant does not appear to have been found any where 
but in the Island of Oahu, whence we also possess specimens, gathered by Rfr. Macrae. 
5. Polypodium pellucidum; frondibus profunde pinnatifidis, laciniis lineai’i-lanceolatis ob- 
tusiusculis repando-dentatis, squamulis dorsalibus submarginalibus albis, venis dichotomo- 
furcatis striisque interstitialibus pellucidis, soris solitariis. Kaulf. Fnum. Fil. p. 101. Gaud, 
in Freyc. Voy. p. 356.
