268 POLYPODIUM, § PHEGOPTERIS. 



Hab. Sandwich Islands, Beechey (frond and upper portion of stipes quite gla- 

 brous and scaleless), Brackenridge. Society Islands, Bidivill (glabrous, and with 

 the pinnules falcate and less deeply piiinatifid). Pitcairn's Island, Cuming, n. 

 1388. Otaheite, Cuming, n. 1414. Ovalau, Fiji Islands, Milne, n. 303.— Brack- 

 enridge (who does not appear to be acquainted with the perfect stipes) observes 

 that " the whole plant has a good deal the habit of P. unidentatum, but is withal 

 distinct." lie may possibly have another plant in view, for he says the ultimate 

 divisions are pellucido-punctate. Truly, however, more perfect, and suites of 

 specimens are required of these large-fronded decompound Polypodia before the 

 correct limits of the species can be defined. 



216. P. (Phegopteris) Aneitense, Hook.; caudex ?, upper 

 portion of stipes and primary and slender secondary rachises 

 pale-brown glabrous and scaleless, frond membranaceous 

 bright-green 18-20 inches long 12-14 inches broad at the base 

 subdelteo-ovate acuminate bipinnate tripinnate below, pri- 

 mary ])innae 6-8 inches long 2-3 inches broad distant, all 

 petiolate broad-oblong acuminate, secondary pinnae all petio- 

 late distant ^-1 inch long from a broad obliquely cuneate 

 base ovate more or less acuminate deeply pinnatifid espe- 

 cially on the superior half, segments oblong or subovate, 

 lowest superior one generally the largest and forming an 

 auricle, entire or subpinnatifid, superior ones entire or with 

 a strong spinelike tooth at its inner margin, ultimate pinnse 

 or pinnules resembling these but smaller, veinlets once or 

 twice forked one to each segment bearing a solitary sorus on 

 the low'er superior branch distant from the margin and always 

 terminal on the veinlet, secondary rachises with a narrow 

 green marginal wing. 



Hab. Aneiteum, one of the New Hebrides, Milne and Macgillivray. —Thh has 

 a very peculiar aspect, and seems quite a new species ; the greater number of the 

 segments or lobes are furnished with a solitary strong spinelike tooth in the 

 inner margin, and the species certainly merits the name of unidentatum rather 

 than the preceding one. 



217. P. (Phegopteris) Keraudrenianum, Gaud.; "caudex* 

 subarboreous prostrate," stipes ? glabrous, main rachis thick 

 as a swan's quill stramineous brown and as w^ell as the se- 

 condary rachises very glossy, fronds ample "12-15 feet long" 

 subscandent coriaceo-merabranaceous bi-tripinnate, primary 

 pinnae distant opposite or alternate subsessile H-2 feet long 



* " Cette fougere forme, par la reunion de ses rudiments petiolaires persistants, 

 une sorte de tronc de plusieurs pieds de hauteur sur 5 a 6 pouces de diametre, qui 

 n'ayant pas assez de force pour se tenir droit, se courbe et se contourne sur le 

 sol. La partie superieure, qui se redresse, est couronnee de feuilles longues de 5 

 a 7 pieds," etc. — Gaudichaud.
