6. Polypodium Adenophorus; caudice squamoso, squamis lanceolato-acuminatis, stipite 
brevi clavato-glanduloso, frondibus elongato-lanceolatis profunde pinnatifidis, laciniis tri- 
angulari-oblongis obtusis integris parce ciliatis, rachi concolore piloso-glandulosa, capsulis 
glandulis clavatis immixtis. (Tab. XXIL) — P. pendulum. Gaud, in Freyc.Voy. p.%^*d. 
(non Sw .) — Adenophorus pinnatifidus. Gaud, in Freyc. Voy. p. 365. 
Caudex crassiusculus, brevis ? repens ? dense squamosus ; squamis imbricatis, lanceolato-acuminatis, reti- 
culatis, membranaceis, intense fuscis, nitidis. Stipes brevis, vix unciam longus, teres, superne fronde decur- 
rente alatus, pilis glandulosis, clavatis, rubris, patentibus tectus. Frons spithamsea ad pedalem, erecta ? elas- 
tice membranacea, pallide virens, elongato-lanceolata, apice acuminata, inferne sensim attenuata, medio 
unciam lata, per totam longitudinem profunde, fere ad racbidem, pinnatifida; laciniis hoi’izontaliter pin- 
natifidis, oblongis, basi latioribus, sensim attenuatis, obtusis (bine subtriangulari-oblongis), integerrimis sed 
marginibus paululum sinuatis, pilis subglandulosis parce ciliatis, cseteroquim glabriusculis. Racliis viridis, 
utrinque subpromiiiens, gianduloso-pilosa. Sori 1-12 in singula lacinia, arete dispositi, biseriales. Capsules 
fuscse, pilis claviformibus glandulosis rubris immixtae. 
This has assuredly very much the habit of the well-known P. pendulum of the West Indies, and cannot 
genericaUy be separated from it, without violence to natui'e. It differs as a species from that plant, in its 
much greater size, in the dark-coloured longer scales of the short caudex, in the claviform glands of the 
stipes, in the different colour (never black) of the stipes, and, above all, in the presence of the peculiar 
club-shaped glands which are mixed with the capsules, and which, it must be confessed, are similar to those 
which in part characterize the Adenophori — a genus, it has been observed in the leones Filicum, only to be 
distinguished by the habit and peculiar glands, from Polypodium. In both, the sori are at the apex of a 
simple vein, not, that w'e can find, “ dilated into a receptacle."

7. Polypodium polycojrpon; fronde pinnata, pinnis oblongis acuminatis basi truncatis 
bine auriculatis sessilibus sinuato-serratis coriaceis glabris venis superne pubescenti-scabris 
ad marginem attingentibus et in sinubus versus costam redeuntibus, venulis anastomosanti- 
bus medio soriferis, soris numerosissimis. 
The only specimen of this plant is destitute of stipes, and presents a frond 12-14 inches long, ovate. 
Ilachis stout, fulvous, glossy, grooved on the upper side. Pinnae 4-6 inches long, oblong, acuminate, 
nearly an inch broad at the base, truncate, sessile, divided on the upper side, tapering upwards, often sub- 
falcate, rigid, subcoriaceous, glabrous, except on the costa and nerves above. The costa sends forth its 
lateral and horizontal nerves opposite the centre of each tooth ; these extend to the margin, branch off there 
and descend in two opposite divisions to the sinus, whence they again enter the substance of the fl’ond, and 
form, as it were, a parallel intermediate nerve, reaching almost to the costa, and connected with the main 
vein by transverse bars or veinlets, near the centre of which the sori are produced. A somewhat similar 
appearance is observable in Aspidium Pehrueilianum; but there the intermediate nerve seems rather to be 
formed by the junction of the veinlets. 
8. Polypodium Sandwicense; glaberrimum clecompositum tripinnatum, pinnis lanceolatis 
acuminatis, pinnulis oblongis obtusis basi decurrentibus grosse serratis, serratui’is approxi- 
matis acutis subincurvis, soris intra costam et marginem uniserialibus distinctis. 
Of this Fern, we are incompetent to speak as to the habit, size, caudex, or stipes. The two specimens in 
the Herbarium may even not be entire fronds, but portions of a much larger plant. They are two feet long, 
ovate in outline, and rather acute, twice divided in a pinnated manner in the upper part, below thrice or 
almost four times pinnated, every where glabrous ; all the divisions approximate, the primary ones ovate.
