b row n ; st. of barren frond 1-3 in. 1., slender, th in ly clothed with squai-rose
linear écales ; barren f r . 8-12 in. 1., J - f in. br., narrowed very gradually to both

slightly furfuraceous ; veins distant, not reaching the edgfi, fertile f r . not moie
th a n 2-3 in. 1., on a slender stem 4-8 in. 1.—B&. bp. 5. p . 221.
Hab. Brazil, Qardncf, 98, 6927 ; and a plant from Bourbon differs only by its move
distinct raised veins.—This is very likely a narrow-fronded variety of the next, with
which it agrees in clothing and texture.
36. A. Avhertii, Desv. ; rhizmne woody, short-creeping,^ the scales dense,
linear, bright-hrown ; S t . of barren frond 1-6 in. 1., clothed with squarrose linear
browi! scafes ; barren f r . 1 ft. or more 1., J-1 in. br., the point acute, lower
p a rt narrowed gradually, th e edge entire or subrepand ; t e x t u r e ; imdiib and
e d q e slightlv ciliated with scales like those of the stem ; veins fine, conspicuous
usually sifople, 1 lin. apa rt ; fertile f r . 2-3 in. 1., J - | in. br., narrowed suddenly
a t the base, the stem 6-9 in. 1.—i l k . Sp. 5. p . 219.
Hab Bourbon, Natal, Zambesi-land, Fernando Po, Venezuela (A. Klotzschii.Mmiri.),
Guatemala.—A well-marked species, differing from viscomm in texture, clothing, and
veining.
37. A. dimorphum, H k . & Gr. ; rhizome stout, horizontal, the scales lanceolate,
dark-brown ; st. close, 4-6 in. 1., slender, erect, slightly scaly throughout ;
barren f r . 8-5 in. 1., J - | in. b r., the point bluntish, the edgedeeply and irregularly
crenate • texture subcoriaceous ; both sides covered with minute white dots , vefins
subparalleL simple or fo rk ed ; fertile f r . much smaller th an the barren one,
nearly entire.—i f t . Sp. 5. p . 208. H k . ? Gr. t. 146. 2nd Cent. t. 90.
Hab. St. Helena.—The only Elaphoglossum that has the fronds distinctly incised or
crenated.
38 A. viscosutn, Sw. ; rhizmne woody, short-creeping, the scales dense, fibrillose
da rk chesnut-brown ; S t . 3-6 in. 1., firm, erect, furfuraceous, often viscous ;
barren f r . 6-12 in. 1., J-1 in. br., the apex acute, the lower p a rt narrowed
gradually ; texture subcoriaceous ; both sides more or less viscid and minutely
furfura ceous; veins close and fine ; fertile f r . smaller, and on longer stems than
th e others.—« / . Sp. 6. p . 220. H k . ? Gr. t. 64.
Hab Cuba to Brazil and Peru ; Himalayas to Ceylon, Java, and Philippines ; Seychelles
Mascaren Isles, Fqmando Po, Angola.—From the large forms of this we cannot
distinguish clearly A. xaAcmeunn, Karstmianum, dissimiU, and cwvans, Kze. ih e
two latter are described as squamulose, but both our authentic specimens are nearly
naked. The frond often becomes quite naked in an old state, and then the plant is
difficult to recognize. A. stigmatolepis and falcatum. Fée, we cannot separate clearly.
39. A. c i l i a t u m , Pre sl ; r h i z o m e woody, wide-scandent, the scales short, dense,
deciduous, linear, da rk chesnut-brown ; S t . of barren frond 0-9 in. 1., firm, erect,
slightly scaly ; b a r r e n f r . 12-18 in. 1., J - I J iu. br., the point acute, the base
narrowed gradually ; t e x t u r e subcoriaceous ; both s i d e s nearly naked ; the e d g e
deciduously furfuraceous ; v e i n s fine, close, indistinct ; /c r r if e /» . smaller and on
much longer stems th an the others.—A. Preslianum, Fée. « / . b p . 5. p . 220.
{not p . 266).
Hab. Columbia to Peru.—Probably a variety of the last, from which it differs chiefly
by its woody wide-scandent rhizome and larger barren fronds,
40. A. p i l o s u m , H. B. K . ; r h i z o m e woody, the scales large, dense, lanceolate,
pale-brown ; s t . 6-8 in. L, firm, flexuose, slightly scaly ; b a r r e n f r . flexuose,
6-8 in. 1., I in. br., the point acute, th e base narrowed gradually ; t e x i t i t r e
herbaceous ; both s i d e s , especially the under one, clothed with small brightbrown
scales, each like a tu ft of stellate hairs ; veins conspicuous, very close.—
H k .S p . 5. f . 241.
Hab. Mexico to Columbia.—Easily distinguished by its texture and clothing.
41. A, samoense, B a k e r; rhizome short, woody, the scales long, dense, fibrillose,
glossy, d a rk chesnut-brown ; st. 4-6 in. L, clothed with squarrose woolly
deciduous hairs ; barren f r . 6-12 in. 1., 1 - lJ in. br., the point bluntish and the
base narrowed rather suddenly ; texture herbaceous ; surfaces and especially the
midrib clothed with soft bright silky brownish hairs ; veins sometimes twice
forked ; barren f r . much smaller th an the other.—Elaphoglossum, Brack, t. 9.
Hab. Polynesian Islands.—^Very like the last in texture and general habit, but the
scales both of the rhizome and surface are very different. Judging from the figure, the
Chilian A . WebUi, Bory, may be identical with this.
42. A. apodum, Kaulf. ; caud. thick, woody, the scales dense, linear, bright-
brown, crisped ; st. tufted, none or short, when present densely clothed with
squarrose fibrillose bright-brown scales ; barren f r , 1 ft. or more Î., lJ -2 in. br.,
the apex acuminate, the lower p a rt narrowed very gradually ; texture subcoriaceous
but th in ; the edge and midrib densely fringed with soft short brown
hairs ; veins fine, simple or once forked ; fertile f r . much smaller th an the barren
one.—7 f t. Sp. 6. p . 213. H k . ê Gr. t. 99.
Hab. West Indies to Brazil and Peru.—The West Indian specimens are thinner and
less ciliated than the Continental ones.
43. A. seolopendrifolmm, R a d d i; rhizome woody, short-creeping, the scales
long, linear, da rk chesnut-brown, crisped ; st. 4-12 in. 1., firm, erect, densely
clothed with spreading, nearly black, long fibrillose scales ; barren f r . often 1 ft.
1., lJ -3 in. br., the apex acute, the base narrowed g rad u a lly ; textme subcoriaceous
; edge and midrib more or less densely ciliated w'ith scales like those
of the stem, b u t smaller ; veins subparallel, usually once forked ; fertile f r . much
smaller than tlie barren one. — H k , Sp. 5, p . 211. A. barbatum, Karst. A.
erinaceum, Fée.
Hab. Gu.atemala, along the Andes to Peru.—A plant from Fendler has the veins not
unfrequently joining. A. Ilysirix, Kze., seems nearly allied. Au Ecuador plant from
Jameson is densely ciliated not only on the edge, but over the surface. The scales are
iike those of A . hybridum, but much more copious.
44. A. Cumingii, Fée ; rhizome woody, the scales large, ovate, dull-brown ;
S t . G-8 in. 1., firm, erect, clothed in the lower p a rt with similar scales ; barren f r .
8 in. 1., I J in. br., the point blunt, the base narrowed gradually, the edge
densely fringed with minute scales ; texture very tliick ; the upper surface
clothed all over with very minute scattered scales ; veins quite hidden ; fertile f r .
as long b u t narrower th an the barren one.—Fée, Acrostich. 34.
Hab. Philippines, Cuming, 193.—Perhaps a subfurfuraceous variety of decurrens, with
which it agrees in texture and general habit.
45. A. Boryanum, Fée ; rhizmne woody, the scales dense, linear-subulate,
nearly black ; st. tufted, 3-9 in. 1., more or less densely clothed with ovate-
acuminate or lanceolate pale-brown scales ; barren f r . often 1 ft. 1., 3 in. br.,
the point acute, the base rounded ; texture almost papyraceous, flaccid ; both
sides th in ly clothed with small ovate or peltate furfuraceous scales, which fringe
the edge densely ; veins immersed, very distinct, simple or once forked, ending
in black dots within the edge ; fertile f r . much smaller and on longer st. than
the barren one.—H k . Sp. 6. p. 210.
Hab. West Indies.—The Ecuador plant mentioned in “ Sp, Fil.” seems to belong to
4 . seolopendrifolmm.
