104 SANDWICH ISLANDS. [Polypodiacece. 



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. XXII.) — P. pendulum. Gaud, in Freyc. Voy. p. 349. 

 (non Sw.) — Adenophorus pinnatifidus. Gaud, in Freyc. Voy. p. 365. 



Caudex crassiusculus, brevis ? repens ? dense squamosus ; squamis imbricatis, lanceolato-acuminatis, reti- 

 culars, 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 rachidem, piiiiiatitida ; laciniis horizontaliter pin- 

 natifidis, oblongis, basi latioribus, sensim attenuatis, obtusis (hinc subtriangulari-oblongis), integerrimis sed 

 marginibus paululum sinuatis, pilis subglandulosis parce ciliatis, cseteroquim glabriusculis. Rachis viridis, 

 utrinque subprominens, glanduloso-pilosa. Sori 1-12 in singula lacinia, arete dispositi, biseriales. Capsula 

 fuscae; pilis claviformibus glandulosis rubris immixtse. 



This has assuredly very much the habit of the well-known P. pendulum of the West Indies, and cannot 

 generically be separated from it, without violence to nature. 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 Icones 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 we can find, " dilated into a receptacle."

7. Polypodium polycarpon; fronde pinnata, pinnis oblongis acuminatis basi truncatis 

 hinc 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. 

 ]?achis stout, fulvous, glossy, grooved on the upper side. Pinna? 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 frond, 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 Debrueilianum; but there the intermediate nerve seems rather to be 

 formed by the junction of the veinlets. 



8. Polypodium Sapdwicense ; glaberrimum decompositum tripinnatum, pinnis lanceolatis 

 acuminatis, pinnulis oblongis obtusis basi decurrentibus grosse serratis, serraturis 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 lone, 

 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
