THE GENERA AND SPECIES OF CULTIVATED FERNS. 
inches long, adherent to a creeping rhizome ; linear-lanceolate bipinnate, pinnules oblong obtuse, opposite, 
sessile and hairy. Sori, terminal, marginal, confluent. Stipes, raehis, and niidrib of pinna:, covered "with scales. 
12. JV. Marantic, R. Brown. — A rather handsome evergreen Fem ; found in the South of Europe and Madeira. 
Fronds from six to ten inches high, rather stiff, densely covered with scales on the under surface, and adherent 
to a thick, short, creeping rhizome ; ovate-lanceolate, bipinnate, with oblong obtuse pinnules, the lower one 
stalked, superior ones sessile, entire at the apex. Sori terminal, and marginal. 
13. y. tomentosa, Desvaux. — A woolly evergreen stove species; from Mexico. Fronds very handsome, 
about a foot long, tripiunate, with oblong-linear pinnules, and very small segments, which are roundish ovate 
distant and concave, the terminal one large. Sori consisting of a few spore-cases on each segment. Rhizome 
short, creeping. 
14. N. Ecldoniana, Kunze. — This evergreen stove Fern is the most beautiful one of the scaly section, and is 
a native of the Cape of Good Hope. Fronds nearly a foot long, covered on all parts with narrow white scales, 
giving them a woolly appearance ; rather ovate, tripinnate, with oblong-obtuse pinnules, small roundish ovate 
segments, erenate and concave, the margin revolute, lower ones distant, superior ones sessile. Sori terminal, 
consisting of a single row of spore-cases on each segment, partly concealed by the revolute margin. Ehizome 
creeping. 
N. lendigera of some authors is referred to Cheilanthes (Pteridcaj). 
gi/mnos, naked, and gramma writing ; in allusion to 
f\ YMXOGRAMMA, Desvaux.— Name derived from 
iy the linear sori being destitute of a cover. 
Sori linear, forked oblique, subsequently confluent ; spore-cases medial superficial, usually occupying nearly 
the whole length of the venules. Veins forked, free. Frond varying from a 
few inches to three or four feet long, simple pinnate bipinnate or decompound, 
smooth hairy or covered beneath with a rich-coloured farinose powder. Fig. 7 
represents a pinna of 67. tomentosa (med. size). 
1. 67. rttfa, Desvaux (Hemionitis rufa, Swart:). — An ornamental, evergreen, 
stove species ; native of tropical America. Fronds from one to two feet long, 
hairy, pinnate with oblong, obtuse pinnce, stalked, and cordate at the base, 
terminal, adherent to a fasciculate erect rhizome. Stipes and raehis, reddish 
brown. Sori linear medial, forked, oblique, subsequently confluent, on every 
pinna; throughout the frond. 
2. G. tomentosa, Desvaux. — This is a tender, delicate, and beautiful stove 
Fern ; native of Brazil and the West Indies. Fronds bipinnate, hairy and mem- 
branous, from one to two feet long, with oblong-obtuse pinnules, the lower 
ones cordate at the base, terminal one lobed, acuminate. Sori linear, medial, 
forked oblique. Stipes and raehis black, terminal, adherent to a fasiculate 
erect rhizome. 
3. G. CalomcJanos, Kaulfuss. — An ornamental evergreen stove Fern ; from 
Jamaica. Fronds from two to three feet long, covered beneath with a white 
farinose powder, upper side dull green, bi-subtripinnate with lanceolate-acumi- 
nate pinnules, and elongated acuminate lobed segments. Sori forked, medial, 
oblique, confluent, and nearly covering each segment. Stipes raehis and 
midrib of pinnie black, terminal, adherent to a fasciculate erect rhizome. 
This plant frequently goes under the name of 67. peruviana, in cultivation. 
i. G. tartarca, Desvaux. — An ornamental evergreen stove species ; from the warm parts of America. Fronds from 
two to three feet long, covered beneath with a white farinose powder, the upper surface dull green ; bi-sub- 
tripinnate with lanceolate-acuminate pinnules, and roundish ovate or oblong segments, which are distant, the 
lower ones lobed. Sori linear medial, forked oblique, becoming confluent. Stipes raehis and midrib of pinna) 
black, terminal, adherent to a fasciculate erect rhizome. 
5. G. chryaophyUa, Kaulfuss. — One of the most beautiful of all exotics iu cultivation ; an evergreen stove 
species, from the West Indies and South America. Fronds from one to two feet long, covered beneath with a farinose 
powder of the richest golden yellow, the upper surface yellowish green, bipinnate with lanceolate-acuininate 
pinnce, and roundish ovate or oblong pinnules, slightly dentate, distant and pinnatitid, with media] SOri scattered 
on the veins, terminal, adherent to a fasciculate erect rhizome. This Pern, lute most others, varies in cultiva- 
tion according to the treatment it receives ; if subjected to a low- temperature, and a rather dry atmosphere, 
the fronds do not exceed ten inches high, are nearly triangular and of the most intense golden yellow ; but if in 
a temperature of 85-90 1 Fahrenheit, with proportionate moisture, it then becomi 9 more compound, two feet 
high or more, the segments of the pinnules more serrated, and of an exceedingly bright yellow . 
6. G.oehracea, Prqjl ? — An evergreen stove Fern ; from Tern. Fronds from one t and a half foot long, 
pale yellow beneath, the upper surface bright green, terminal, adherent to a tufted rhizome; bipinnate with 
lanceolate-acuminate pinna\ and narrow ohlong-linear dentate pinnules. Sori medial, somowhal BcatteTed on 
the veins. This has the most compact frond of the yellow powdery kinds, and i> shining on the upper surface. 
Known in cultivation under the name of 67. Mass:
