THE GENERA AND SPECIES OF CULTIVATED FERNS. 
10. C. lendigera, Swartz. — An exquisitely beautiful evergreen stove Fern, a native of Mexico and various 
places in South America. Fronds lanceolate tripinnate, one foot long, hairy ; pinnules oblong-linear ; segments 
very small, obovate, revolute and concave. Son consisting of two or three spore-cases on each segment, partly 
concealed by the reflexed margin. Stipes, rachis, midrib of pinna?, and pinnules densely covered with brown 
scales. Fronds terminal, adherent to a short creeping rhizome. 
11. C. viscosn, Link. — A beautiful evergreen stove species, from Mexico. Fronds triangular, one foot high; 
branches tripinnate, light green, and covered throughout with viscid glandulose hairs ; pinnules oblong-obtuse, 
pinnatifid ; segments of the sterile frond dentate. Sori linear, continuous around every segment of the fertile 
frond. Rachis and stipes brown, terminal, adherent to a short creeping rhizome. 
12. 0. radiata, J. Smith: (Adiantum radiatum, Linnceus). — A very delicate and exceedingly beautiful ever- 
green species, native of the West Indies and Tropical America. Fronds glabrous, one foot high, digitate ; 
branches linear, pinnate, radiating ; segments oblong-obtuse, sub-imbricate, petiolate, articulate at the base, 
auriculate, with a crenatc margin. Sori distinct, often crowded throughout the frond ; indusium reniform. 
Rachis and stipes ebeneous, terminal, adherent to an erect fasciculate rhizome. 
(HASSEBEERA, Kaulfuss. — Name commemorative of/. H. Casscbcer, a German botanist. 
(\J Sori round distinct, or contiguous and confluent, constituting a linear continuous, or interrupted compound 
marginal sorus. Indusium linear, plane plicate or vaulted, attached trans- 
versely across the sporangiferous apices of the venules, rarely infra- 
marginal, sometimes very narrow. Veins forked ; venules direct, their 
apices £rve and sporangiferous. Fronds from one to one and a half foot 
long, palmate, pinnate or bi-tripinnate, glabrous, squamose or farinose. — 
The species upon which this genus was originally established has a gemi- 
nate sorus, with a notched or two-lobed indusium ; that is, the spore-cases 
arising from the apex of four venules are included under one infra- 
marginal indusium. There is no fern at present in cultivation which 
agrees to this character; those we have followed Mr. Smith in placing here 
are of a similar habit and venation, but in the structure of their sori and 
indusium are analogous to Cheilanthes or Pteris. Fig. 34 represents a 
pinna of 0. farinosa (full size). 
1. C. farinosa, J. Smith: (Pteris, Swartz; Cheilanthes, Hooker.) — 
An exceedingly beautiful evergreen stove Fern, from Nepal. Fronds 
glabrous, triangular, one to one and a half foot long, bipinnatifid ; seg- 
ments oblong-obtuse, the upper surface dull green ; densely covered 
beneath with a white farinose powder. Rachis and stipes ebeneous ; ter- 
minal, adherent to a fasciculate erect rhizome. Sori linear, continuous, 
subsequently confluent; indusium universal throughout every segment 
of the frond. 
2. C. peduta, J. Smith : (Pteris, Linnceus.) — A beautiful dwarf ever- 
green stove Fern, native of the East and West Indies, and Islands of the 
Pacific Ocean. Fronds glabrous, triangular, six to ten inches high, five- 
parted ; segments drooping, linear acuminate, pinnatifid, and of a lively 
green. Sori oblong or linear, continuous; indusium narrow. Rachis and stipes ebeneous, terminal, adherent to 
a somewhat creeping rhizome. 
3. C. inframarginalis, J. Smith: (Pteris, Kaulfuss.) — Avery delicate evergreen greenhouse species, from 
Mexico. Fronds ovate-lanceolate, glabrous, one foot long, bipinnatifid or tripinnatifid below; segments linear- 
acuminate; margin serrate. Sori linear, continuous, consisting of a single row of spore-cases, inframarginal ; 
indusium plane, linear, continuous. Rachis and stipes slender, dark brown, terminal, adherent to a somewhat 
creeping rhizome, 
•1. 0. hastata, T. Smith : (Pteris, Linnwus). — An ornamental evergreen greenhouse species, from the Cape of 
G 1 Hope. Fronds glabrous, one to one and a half foot long, l.ipinnate; pinn.o cordate, yellowish groin, ovate- 
acuminato or hastate; the margin crenate. Sori linear ntinuous; indusium plane. Kaehisand stipes dark 
brown, terminal, adherent to a short creeping rhizome. Two forms of this plant are in cultivation, the one lot 
than the other, but not otherwise different. 
o. O.otmmta, J. Smith; (Cheilanthes, Link). — Aneat evergreen greenhouse Fern from Me\ieo. Fronds glabrous, 
bipinnate, six to ten inches high, of a lively green; fertile pinnacles oblong acuminate, pinnatifid, with the 
segments narrowed at the base; sterile segments, oblong, wedge-shaped, and serrate at the margin. Sori li 
Rachis and stipes ebeneous ; rhizome somewhat creeping. 
PLAT 1 ! l.t'M \, ./. Smith : (Pteridi \ sp. of Authors). — Name derived from pi i. and loma, a margin, in 
allusion to the broad marginal sori. 
Sori linear oblong, continuous, subsequently confluent, occupying a portion of the upper half of the venules, 
forming a broad marginal hand. Indusium narrow, attached transversely to the enter margin of the broad [ rj
