the segments often free and more than 1 inch long, the stipes and rachis are rigid. 

 It has some affinity with P. suspensum.

 with spreading similar hairs 3-14 inches long ,^j-l inch wide 

 linear- or oblong-lanceolate membranaceous brownish-green 

 flaccid pinnated, pinnae ovate-oldong horizontal obtuse the 

 superior base a little produced the inferior slightly decurrent 

 entire uppermost rarely coadunate, lowest ones moderately 

 abbreviated, costule rather remote simple, veins apparent, 

 sori one or tvvo on each segment near the apex or two on 

 each side between the costule and the margin, capsules se-

 1018. — A good species, but it is impossible to separate from it the small form 

 which has gone by the name of P. elasticum. It is best perhaps distinguished from 

 its allies by the much pinnated, very fusco-villous fronds, and the peculiar shape 

 of the pinnae. The upper base is rounded off and hence a little free and separate 

 from the rachis, while the lower base is decurrent, so that the pinna; are un- 

 equally sided. The South American specimens from tlie aliove localities are iden- 

 tical with those from Mauritius and Bourbon. My authentic ones of P. xantlio- 

 trichum, Kl. (P. ellipticosorum, Fee, according to Mettenius), prove that it is the 

 same as P. cultratum. 



G8. P. (Eupolypodium) oblicjuatum, Bl. ; caudex short 

 creeping rather stout ferrugineo-paleaceous, stipites approxi- 

 mate 2-3 lines to H inch long glabrous, fronds firm-mem- 

 branaceous scarcely subcoriaceous 6-12-14 inches long 1^-2 

 inches broad lanceolate acuminate and subcaudate tapering 

 below deeply pectinato-pinnatifid nearly to the base, seg- 

 ments aj)proximate from a broad base lineari-acuminate often 

 acute entire, lower ones gradually shorter, the lowest trian- 

 gular much abbreviated, costule and simple oblique veins
