THE GEXEIIA AND SPECIES OF CULTIVATED FERNS. 
u-r 
three feet long, with linear-lanceolate pinnatiiid rather memhranous pinna?. Stipes and raehis green ; lateral, 
adherent to a short creeping rhizome. Sori medial. 
5. 67. pennigera, Presl. — An ornamental evergreen stove fern, from New Zealand. Fronds pinnate, slightly 
pubescent, one or two feet long, with lanceolate-acuminate pinnatifid slender bright green pimva?, roundish at the 
base, and bluntly lobed. Fertile fronds contracted, erect. Raehis and stipes round, pale green, terminal, 
adherent to a creeping rhizome. Sori medial, subsequently confluent. 
6. 67. prolifcra. Presl ( Meniscium, Swart:). — A straggling growing evergreen 
stove fern, from the East Indies. Fronds slender, pinnate, two to three feet long 
with oblong acuminate membranous pubescent pinna;, slightly cordate at the 
base, and erenato-dentate at the margin. This fern grows freely, is very proli- 
ferous, pale green, but without fructification. The fronds are lateral, adherent 
to a creeping rhizome. 
/luXIOPLTLEMUAr, Presl (Polypodii, sp. of Authors).— Name derived from 
(£f gonia, an angle, and phleps, a vein, in allusion to the angles formed by the 
anastomosing of the venules. 
Sori round, terminal, naked or squaniiferous, arranged in one or more trans- 
verse parallel rows. Veins forked or pinnate, the lower exterior venule free and 
fertile, the others angularly anastomosing, producing from their junction an 
excurrent, free, and generally fertile veinlet. Fronds from a few inches to 
five or six feet long, smooth hairy or scaly, simple pinnatifid or pinnate, the 
pinna; entire, articulate, serrulate or undulate. — This is an exceedingly variable 
genus with regard to the size of the plant and circumscription of the fronds, 
but several of them are amongst the most elegant of the ferns in cultivation. 
The dwarf kinds have the fertile fronds contracted, while the larger species have 
their fronds all of one form ; but they agree in having a crespitose, scaly, 
creeping rhizome. The species are commonly found adhering to the trunks of 
trees in tropical forests. The characters by which they are determined from all 
congeners, are the round terminal sori, combined with the angular anastomosing 
of the venules, and the costal arcole having an excurrent veinlet, which is 
generally soriferous. Fig. 11 shows a pinna of G. meniscifolium (full size). 
1. 67. vaccinifolium, J. Smith : Langsdorf aud Fischer. — A dwarf, creeping, 
evergreen, stove species ; from the West Indies and South America. Fronds of 
two lands : sterile — simple, glabrous, sub-rotund or oblong, deeurrent at the 
base, dark green, about half an inch high ; fertile — linear, simple, glabrous, two 
inches long, deeurrent at the base ; both kinds are lateral, articulated on a 
thick, brown, scaly, creeping rhizome. Sori terminal, uniserial. 
2. 67. pitosclloittes, J. Smith : Linnams. — A dwarf, evergreen, stove species ; 
from the West Indies. Fronds of two kinds : sterile — simple, hairy, light green, 
ovate or oblong, deeurrent at the base, from one to two inches high : fertile — 
simple, hair}', linear-oblong, deeurrent at the base, from two to three inches 
long ; both are articulated on a very slender, creeping, rhizome. Sori seated in 
a tuft of narrow scales, uniserial. 
3. 67. incanum, J Smith: Swartz. — A dwarf, evergreen, stove fern; native 
of the AVest Indies and various parts of South America. Fronds pinnatifid, six 
to twelve inches long, lanceolate, the upper surface didl green densely covered 
beneath with roundish, fimbriate, peltate, brown scales; fronds lateral, articu- 
lated on a scaly creeping rhizome; segments oblong-obtuse, coriaceous. Sori 
immersed, sub-marginal, uniserial. Veins internal and indistinctly seen. 
4. 67. seputtiim, J. Smith : Kaulfuss. — An elegant, evergreen, stove species ; 
from South America. Fronds lanceolate, pinnate, from one to one and a half 
foot long, densely covered throughout with narrow, fimbriated scales, which 
give them a whitish appearance; they have close sessile, oblong-linear, rather 
obtuse pinna;. Sori imiscrial on the tipper half of the frond, protruding through 
the scales. Veins internal, indistinctly seen. Fronds articulated on a white, 
scaly, creeping rhizome. 
5. 67. arffutum, J. Smith: Vallieh. - A beautiful, evergreen, stove fern; N^V-l 
from Nepal. Fronds glabrous, slender, from two to three feel long, the rai bis \ | 
and stipes pale brown, shining, and articulated on a scaly, creeping rhizome. 
Fronds pinnate, lanceolate, with lanceolate-acuminate, rather membranous, bright 
green pininc, which arc articulated with (he raehis, serrated, and deourrent at the 
base. Sori large, uniserial, yellowish brown, each furnished with numerous lacimated scales, which arc soon obli- 
terated by the swelling sori ; they are immersed, forming elevated n of the frond.
