the frond.—/ f t . Sp. 2. p . 10. t. 80. B.
Hab Mexico, province of Oaxcaca, at an elevation of 3,000 ft,, Galeotti, 6561.—A very
distinct species, easily recopized by its large round equal-sided pinnules. The venation
I S very clearly marked on the under side of the frond, but is quite flabellate, and there is
no central nb which is stronger than the others.

12. K. mtermedmm, Sw a rtz ; st. 6-12 in. ]., erect, strong, polished, hut

unequal-sided, but not dimidiate, the lower h a lf being the smallest, about thè
inner th ird being cut off, the point bluntish or acute, the inner edge nearly
parallel with the stem, the upper n early straight, scarcely tootlied ; texture
subcoriaceous ; rachis tomentose; sori in interrupted marginal patches, 1 - 2 lin
imross, placed round the upper edge and outer two-thirds of the lower one.—
±l/c. bp. 1. p . 26. A. fovearuin, Raddi. A. triangula tum, Kaulf.
Hab. Tropic,al America, from Mexico and the West Indies southward to Peru and Rio
Janeiro.--A widely-diffused and well-known species, distinguished from A. tetraphylhmi
by the outer edge being often brought down so as to be parallel with the upper edge,
so that we have two opposite rows of sori instead of one at an acute angle with the
t t ;, ihe stems naked and polished. Sp. 13-20.

swi numerous, o bverse? reniform, as deep as broad, placed in distinct hollows
round the outer edge.—H k . Sp. 2. p . 9. t. 73. B.
Hab. Mexico, gathered originally by Mr. Bates in 1834 ; and fine specimens have
been received lately from Morelia from Mr. Glennie.—In the texture of the frond and
form of the sori this curious plant closely resembles A . Qaleottianum, but the stem is
quite simple, so far as we know, the form of the pinnules quite different, and the habit
is very peculiar.
14. A. sinuosum, G a rd .; st. 4-8 in. 1., erect, naked, polished, nearly b la c k ;
f r . with a long terminal central pinna, 2-3 in. hr., and 1 or 2 pairs of erecto-
patent branches a t the base ; pinnl. 1 J-in. hr., J - J in. deep, the lower line obliquely
decurved, the upper ir re g u la r ? rounded and deeply lobed, the lobes again
crenate, the lower ones on stalks J - J in. 1 . ; texture papyraceo-herbaceous;
rachis and surfaces naked ; sori ohreniform, placed in rounded sinuses of the
crenations of the lohes.—/ / / . S p. 2. p . 35. Ic. P I. t. 604.
Hab. Brazil, Gardner, 3552, Burchell, 6752 ; and a similar plant has been gathered by
Prof. Jameson near Guyaquil.—This resembles most A. Qapillus-veneris in the segments.
They come generally about halfway between the fiabellato-cuueate and truly dimidiate
types of form, so that its position may be said to be about midway between that species
and A. trapezifoi'me.
16. A. diaphanum, Blume ; sl. 4-8 in. 1., slender, erect, blackish, polished ;
f r . 4-8 in. 1., 1 in. hr., simply pinnate or with 1 to 3 branches a t the base, which
are sometimes n e a r ? as large as the terminal one ; pinnl. J in. hr., J in. deep,
the lower line rather decurved, the upper nearly parallel with it, crenate like
the blunt outer ed g e ; texture th in ; rachis naked, surfaces nearly s o ; sori
obversely reniform, numerous, b u t not contiguous, placed in the sinuses of the
/ - upper and outer edge.—/ f t . Sp. 2. p . 11. t. 80. C. A. affine, H k . Sp. 2. p . 32.
non Willd. A. setulosum, J . Sm.
Hab. S. E. China, Aneiteum, Java, Fiji, New Caledonia, Norfolk Island, N. Zealand, N. S.
Wales.—This is nearest the next species, but is inucb less branched, and the pinnules are
thinner in texture. In habit it shows an approximation towards the pedate group. I t
is not unlikely that A. erectum, Kunze (Bot. Zeit. 1848, p. 211), is the same.
10. A. affine, W illd .; st. 6-9 in. 1., erect, polished, blackish, glossy ; f r . with a
terminal central pinna 4-6 in. 1., 1 - lJ in. hr., and several smaller erecto-patent
lateral ones, the lowest of which are again branched ; pinnl. J - | in. 1 ., J in. deep,
dimidiate, tlie lower edge straight, the upper nearly parallel with it, crenate like
the oblique or b lu n t? rounded outer edge ; texture subcoriaceous ; rachis and
surfaces quite naked, the latte r very glaucous; sori numerous, roundish, placed
in small hollows round the upper and outer edge.—A. Cunninghami, H k . Sp. 2.
p. 52. t. 8 6 . A. (not A. aifiiie, H k ., which is A. diaphanum, -
Hab. New Zealand.—A somewhat variable plant in branching and the size of the
segments, but not likely to be confused with any other, especially as it is known only in
New Zealand.
1 7 . A. nigrescens. Fée ; st. 6-12 in. 1., strong, erect, naked, blackish, polished ;
f r . 6-9 in. ]., 4-0 in. br., with a terminal pinna and several lateral ones on each
side, the lowest of which are again hranclied ; segm. about J in. 1 ., J in. hr.,
dimidiate, the upper and lower margins n e a r ? parallel, the point b lu n t ? rounded,
the upper aud outer edges f in e ? toothed ; texture coriaceous ; rachis nearly
naked, polished, surfaces naked ; sori in transversely oblong patches along the
upper edge.—Fée, Icon. t. 11. f . 2.
Hab. Guadeloupe, Z’/Armmie?'.—Pioljably this should be regarded as a subglabrous
state of A. cristatum. From all the species placed near, it may be known by its coriaceous
and much smaller segments.
