oblong subfalcate acute and mucronate, those of the inferior, 

 primary pinnae free distant entire or again pinnatifidly pin- 

 nate, veins forked, involucres intramarginal, stipes terete 

 and flexuose, rachis ferruginous and costa beneath thickly 

 muricated with hard spinous points. (Tab. CXXIII. B.) 



Hab. Tropical America, Antioquia in New Granada, Mr. Jervise. — If not sui 

 generis botanically speaking, it may truly be called sua; speciei, for I know none 

 with which it can be confounded ; in texture and somewhat in ramification it 

 approaches the Aquilina group, but it is remarkable for the flexuose rachis, and 

 that, together with the portion of the stipes which is attached to the frond, 

 covered with numerous, close-placed, small spinous tubercles, or rather raised 

 points. Something of the kind is seen on the stipes and rachis of Pt. paleacea, 

 when the scales aVe fallen off. — Antioquia, the native country of our plant, is in 

 the very centre of tropical America, between 5° 40' and 8° north, long. 75° and 

 76° 30' west, in the department of Cundinamarca, a country abounding in moun- 

 tains, and almost unknown to the botanist, whom it would repay well in the 

 exploring its vegetable riches. 



62. Pt. (Eupteris) muricella, Fee ; " fronds pinnated above 

 and bipinnated at the base of a soft consistence transparent 

 with oblong toothed segments crenulated at the apex having 

 on the rachis of the pinnules and on the costa long sharp 

 soft and whitish points, petiole strongly furrowed reddish, 

 rachis whitish, sporothecia short occupying the middle of 

 the lobes {medians) with a rather large reddish indusium." 

 Fee, Fil. 8me Mem. p. 73. 



Hab. Mexico, near Cordoba and Iluatusco, Schaffner, n. 143. — "Soft and 

 delicate species, allied to Pt. repandula,* Link, Sp. Fil. p. 56 ; but in our plant 

 the apex of the segments is strongly crenulated, while it is said of Pt. repandula, 

 ' pinnulis integerrimis,' a character found in the Pt.nemoralis, Willd." 



63. Pt. {^\x\)tex\s) paucinervata, Fee; "fronds pinnate at 

 the base and pinnatifid at the apex which is terminated by a 

 long linear undulated point, rootstock [sonche) upright with 

 long greyish radicles, petioles smooth reddish glabrous, basal 

 pinnules pinnatifid erect, sterile segments oblong toothed 

 crenulated at the apex obtuse fertile segments entire falcate 

 both with distant and very few nervils, sporothecia arising 

 from the base of the segments rather large and furnished 

 with a very small indusium." — Fee, Fil. 8me Mem. p. 73. 



* It will be seen in a note at p. 182, that Mettenius considers Pt.felosma, 

 J. Sm., and Pt. repandula identical. The latter is thus distinguished: — 



" Pt. repandula, Link ; fronde bipinnatifida, pinnellis lanceolatis siibfalcatis 

 obtusis integerrimis et repandulis, ala connectente angustissima. Brazil. PI. 

 hiaurita, Ilort. Berol. 11. p. 28. — Affinis Pt. biaurita, var. edentula, Kze., Linnaea, 

 ix. 75, sed pinnulte ad rachin separatse." — All we know of this plant.
