THE GENERA AND SPECIES OF CULTIVATED FERNS. 
6. 67. verrucosum, J. Smith. — An ornamental, evergreen, stove species; from the Philippine Islands and 
Singapore. Fronds slender, slightly puhescent, four to five feet long, pendulous, lanceolate-acuminate, with 
ohlong-acuminate, undulated, bright green pinna?, which are slightly serrated, round at the base, and articulated 
with the rachis. Sori uniserial, immersed, forming elevated protuberances on the upper surface of the frond. 
Rachis and stipes scaly and articulated to a creeping rhizome. 
7. 67. subauriculatum, Blume. — A very elegant, evergreen, stove species ; from Java and Luzon. Fronds 
slender, lanceolate, pinnate, from four to six feet long, with long, narrow, lanceolate-acuminate, membranous, 
bright green pinna?, which are serrate, sub-auriculate at the base, and articulated with the rachis. Sori uniserial, 
yellowish brown, each furnished with numerous laciniated scales, which are soon lost by the swelling sori ; they 
are immersed, forming elevated protuberances on the upper surface. Rachis and stipes brown, pubescent, articu- 
lated with a scaly, creeping rhizome. This species is decidedly the most beautiful of the Polypodiea?, and un- 
questionably the most ornamental of all herbaceous species yet in cultivation ; the fronds being long and very 
slender, they consequently assume a pendulous position. A plant, probably the first introduced to Britain, at 
present growing in a basket suspended from the roof of the Orchid House, at Eew, has on it nearly twenty 
developed fronds, some measuring eight feet long, and having fifty-eight pairs of pinnules, with a stipe not more 
than eight inches long. 
8. 67. Catharines, J. Smith : Langsdorf and Fischer. — An evergreen, ornamental, stove fern ; from Brazil 
Fronds glabrous, broadly lanceolate, from one to two feet long, dull green, articulated on a creeping rhizome, 
which is densely covered with imbricated, peltate, acuminate, brown scales ; pinnatifid, with obloug obtuse seg- 
ments. Sori uniserial, confined to the upper half of the frond. 
9. 67. harpeodes, J. Smith : Link. — A tall evergreen, stove species ; from 
Brazil. Fronds glabrous, broadly lanceolate, three to four feet long, dull 
green, nearly erect, with stipes nearly half the length of the fronds ; they are 
articulated on a thick, scaly, creeping rhizome. Frond pinnatifid, with 
lanceolate-aeuminate, nearly entire, scimetar-shaped pinnae, the lower ones 
standing forward. Sori large, yellowish brown, uniserial. 
10. 67. latipes, J. Smith : Langsdorf and Fischer. — A neat, evergreen, 
stove fern; from Brazil. Fronds glabrous, pinnatifid, one to two feet long, dull 
green, somewhat slender and pendulous, lateral, articulated on a green, creep- 
ing rhizome, which is covered with peltate fimbriated scales ; pinnules linear- 
oblong, rather obtuse, membranous, undulated and repand. Sori small, biserial. 
11. 67. albo-pimctatiim, J. Smith: Raddi. — A very ornamental, evergreen, 
stove species; fromBrazil. Fronds broadly lanceolate, pubescent, pale green, 
from two to three feet long, the upper surface scattered over with small 
white scales; they are lateral, articulated on a scaly, creeping rhizome. 
Fronds pinnate, with lanceolate-acuminate, nearly entire, membranous, undu- 
lated pinna?, having the inferior base truncate, superior adnate ; the upper 
ones sessile. Sori uniserial. 
12. 67. dissimUe, J. Smith: Linnaeus. — A handsome, evergreen, stove fern; 
from the West Indies. Fronds slender, pendulous, two to three feet long, 
pubescent, pale green, articulated on a scaly, creeping rhizome. Fronds lan- 
ceolate, pinnate, the pinna? distant, sessile, sub-falcate, lanceolate-acuminate, 
membranous, undulated and somewhat deflexed, the lower ones standing 
forward. Sori biserial. 
13. G. mcniscifolium, J. Smith: Linna?us. — A tall, glabrous, evergreen, 
stove species ; from Brazil. Fronds three to four feet long, pinnate, with 
lanceolate-acuminate, undulated, shining, bright green pinna?, from six to 
eight inches long, having their inferior base roundish, and the upper one 
adnate. Sori large, yellowish brown, generally biserial. Stipes and rachis 
green, lateral, articulated on a scaly, creeping rhizome. 
14. 67. defexum, Hort. — An ornamental, evergreen, stove fern; from Brazil. 
Fronds glabrous, two feet long, pinnate, with lanceolate-acuminate coriaceous, 
undulated, deflexed pinna?, of a dull green, roundish at the base and articulated 
with the rachis ; the lower pinna? are often divided. Sori biserial. Stipes 
and rachis blackish green, lateral, articulated on a scaly, creeping rhizome. 
tflYRTOPHLEBIUM, E. Brown. (Polypodii sp. of Authors).— Name derived 
(y from Icyrtos, curved, and phlcps, a vein; alluding to the convex or curved 
form of the venules. Mg. 12. 
Sori round, naked, lateral or terminal, arranged in two rows between and parallel with the primary veins or 
irregular. Veins pinnate or forked, the lower exterior venule free and fertile, the others arcuately or angularly 
anastomosing, producing from their exterior side two or more exeurrent, free, fertile veinlets, which are sometimes
