PTERIS. 205 



Hab. Shady places, mountains of Java, Blume. — " A Pt. biaurita, L., differt 

 laciniis serratis intermediis acutis." Bl. — Agardh questions if it should not be 

 referred to Pt. quadriaurita ; — and then it would be of the § Eupteris. 



72. Pt. (Campteria?) atrovirens, Willd. ; fronds pinnate, 

 pinnae subopposite pinnatifid, segments oblong obtuse un- 

 equally toothed at the apex, lowest pinnae bipartite, stipes 

 smooth," Willd. Sp. PL v. p. SS5. —Ag. Sp. Gen. Pterid. p. 28, 

 in note. 



Hab. Oware and Benin, western tropical Africa, Dr. Fliigge. — " Resembling 

 Pt. biaurita, but the frond is thicker, more rigid, black-green," and, I think, 

 may safely be referred to Pt. biaurita, a very common species in Western 

 Africa. 



73. Pt. (Campteria?) armata, Pr. ; "fronds cordato-ovate 

 glabrous glaucescent pinnate, pinnae opposite sessile pinna- 

 tifid lowest ones bipartite, segments linear obtuse entire 

 unequal, terminal one elongated repand, secondary rachises 

 and costa above spinose, stipes smooth," Presl, Reliq. Hank, 

 p. 56. — Aff. Sp. Gen. Pterid. p. 29, in note. 



Hab. Island of Sorzogon, Hamke. — "A Pt. pungente diversissima," Pr. — 



Probably this should be referred to the free-veined Pterides, and perhaps to Pt. 

 quadriaurita. 



{Tri-quadripinnate ; primary ramifications ternate.) 



74. Pt. (Campteria) triplicata, Ag. ; frond bi-tripinnate 

 1-2 feet long firm-membranaceous, pinnae ternate and as well 

 as the pinnules long-petiolate, pinnules almost a span long 

 deeply pinnatifid, segments oblong very obtuse or retuse 

 coarsely serrated where sterile, veins forked basal ones united 

 and forming an angular arch between the costules, sori nar- 

 row continued to the very apex, stipes channelled smooth. — 

 Ag. Sp. Gen. Pterid. p. 29. 



Hab. Madagascar, Goudot, Bernier ; Mozambique, "Forbes, in Herb. Hook." — 

 A very distinct and remarkable species, especially in the disposition of the pri- 

 mary pinnae to ramify in a ternate manner ; the pinna; and pinnules are long- 

 petiolate. The longest pinnules are nearly a span long ; all are lanceolate, pin- 

 natifid, with an elongate terminal segment, serrated where destitute of fructifi- 

 cation. The lateral segments or lobes are an inch and a quarter long, ^ of an inch 

 broad, singularly obtuse or even retuse. The sori are copious on almost every 

 segment and extending to the apex. The involucre is of a firm texture, very 

 narrow, dark brown. 



75. Pt. (Campteria) Pseudolonchitis, Bory; "fronds bipin- 

 nate, lowest pinnae bipartite and as well as the jjinnules pin- 

 nato-partite, segments serrated, those of the pinnae lanceolate 

 acuminate, of the pinnules oblong obtuse, primary veins 

 monarcuate, secondary ones and veinlets all forked," Ag. 

 —Bory, MSS. Willd. Sp. PI. p. 389. Poir. Encycl. Method.
