s 
cent, one foot long, peetinate-pinnatifid ; segments rather membranous, linear-lanceolate, acute, pale green, and 
slightly falcate. Stipes scaty near the base ; terminal, adherent to a creeping rhizome. 
3. B. trimigulare, Link. — An evergreen greenhouse species, from Mexico. Fronds glabrous, lanceolate, a 
foot or more long, deep green, pinnate ; pinna; usually alternate, sessile, oblong-acuminate, slightly falcate, in- 
ferior ones distant, terminal one entire, and caudate. Stipes scaly ; terminal, adherent to a creeping rhizome. 
4. B. brasilicnsis, Desvaux (B. corcovadense, Baddi). — A large-growing evergreen stove species, from Brazil. 
Fronds lanceolate, four to five feet long, pinnate, deep green ; pinnae adnate deourrent, rigid, repand, linear- 
lanceolate, oblique, 7 — 8 inches long, undulated, margin spinulose-serrate. Stipes 2 — 3 inches brag, scaly; ter- 
minal, adherent to an erect caudex, attaining the height of two feet or more. 
5. B. mtstrale, Linnaeus ? (B. pectinatum, Sort.) — A very elegant evergreen greenhouse species, from the 
Cape of Good Hope. Fronds slender, lanceolate, light green, one foot long, pinnate ; pinnae rather membranous, 
sessile, slightly falcate, linear-lanceolate, lower ones standing forward, distant, sub-auriculate on the superior 
base ; the terminal one entire and caudate. Eachis pubescent ; stipes reddish, with a few scattered scales at the 
base ; terminal, adherent to a creeping rhizome. 
6. B. cartilagmeum, Swartz. — An ornamental evergreen stove or greenhouse species, from New South "Wales. 
Fronds broadly lanceolate, pinnate, three feet long, light green; pinna; sessile, with a dilated base, linear- 
lanceolate, oblique, eight inches long, undulate, the apex mucronate, spinulose-serrate at the margin. Stipes 
about six inches long, muricated, and densely covered with narrow dark scales. Fronds terminal, adherent to a 
thick creeping rhizome. 
7. B. occidentale, Linnaeus. — An ornamental evergreen stove Fern, from the West Indies and Brazil. Fronds 
lanceolate, pinnate, a foot or more long, of a lively green ; pinnae sub-sessile, falcate, subcordate-lanceolate, 
lower ones distant ; terminal one entire and caudate, acute, with small spinulose teeth on the margin. Eachis 
glandulose-pubescent. Stipes scaly near the base ; terminal, adherent to a creeping rhizome. 
S. B. hastatiim, Kaulfuss (B. trilobum, Prcsl). — A glabrous evergreen greenhouse Fern, from Chili. Fronds 
lanceolate, a foot or more long, light green, pinnate ; pinna; linear-lanceolate, acute, falcate, inferior hastate, 
petiolulate, superior sessile, auriculate at the base. Stipes scaly at the base ; terminal, adherent to a creeping 
rhizome. Sori linear, continuous or interrupted, medial. Indusium fringed on the margin. 
9. B. intermedium, Link (B. longifolium, Humboldt). — A dwarf evergreen stove species, from Brazil. Fronds 
glabrous, six or eight inches long, pinnate, light green ; pinna; oblong-ovate obtuse, terminal one large and 
elongate, lower petiolulate, upper adnate. Eachis and stipes reddish, with a few scales near the base ; terminal, 
adherent to a creeping rhizome. This little plant has only two pairs of pinnae on each frond, and the terminal 
one is about four inches long. 
10. B. graeiU, Kaulfuss. — A graceful evergreen stove Fern, from Brazil. Fronds glabrous, slender, pinnate, 
dark green, a foot or more long ; pinna; lanceolate, sub-falcate, inferior petiolulate, superior adnate, terminal one 
elongate. Eachis and stipes reddish, with a few scales near the base ; terminal, adherent to a creeping rhizome. 
11. B. serrulatum, Eichard (B. angustifolium, WUldenow). — A beautiful evergreen stove Fern, from the 
Mauritius. Fronds glabrous, pinnate, two feet long, bright green ; pinna; rather membranous, lanceolate, petio- 
late, obliquely truncate at the base, with a cartilaginous serrated margin, ar- 
ticulate with the rachis, and having a few small cordate scales on the costa ; 
terminal, adherent to a peculiar elongated creeping rhizome. 
BOODIA, li. Brown. — Name commemorative of Samuel Doody, a London 
apothecary, and the first British cryptogamist. 
Sori oblong, straight or arcuate, transversely uniserial or biserial, pro- 
duced on the transverse anastomosing, or arcuate venules. Indusium plane, 
of the same form as the sori. Veins forked ; venules arcuately anastomosing 
near their base, where they are generally soriferous ; then direct and free 
towards the margin. Fronds pinnatifid or pinnate, from eight to eighteen 
inches long, rigid, uniform, or the fertile ones contracted, margin spinulose. 
— The few species on which this genus is established are of a very rugose 
nature, and are natives of New Holland, New Zealand, and the Sandwich 
Islands. The uniformity of aspect, habit, and venation developed through- 
out the species that are in cultivation is so great, that these are expressive 
characters of the genus, even in the absence of fructification. Their nearest 
affinity is with "Woodwardia, from which they are principally distinguished 
by having a more superficial sorus and simple venation. Fig. 41 represents a 
small portion of a frond of I), blcclinoidcs (nat. size). 
1. D. eaudata, E. Brown (D. rupestris, Kaulfuss). — A pretty little ever- 
green greenhouse Fern, froni New South Wales and Van Diemen's Land 
Fronds of two kinds. Sterile linear-oblong, glabrous, pinnate, six inches 
long ; pinnae oblong-obtuse, inferior petiolatc, superior adnate, margin spinu- 
lose-serrate. Fertile contracted, glabrous, linear-lanceolate, six to eight inches high, pinnate; pinnae linear, MJv
