fronds Hinple lanceolate ferrate fubfeflile. The root con- 
fids of brown fibres, fending up eight or nine lronds, three 
inches long, three quarters of an inch broad where broad- 
eft, yellowifh green, narrow at the beginning, increafing 
to near the end, and then decreating to a blunt point. Na¬ 
tive of woods in the inland parts ot Jamaica. 
6. Afplenium plantagineum, or plaintain-leaved fpleen¬ 
wort : fronds fimple ovate-lanceolate lubcrenate, ttipe 
four-cornered. This feldom rifes above ten or tw f elve 
inches; the fronds rife from a thick fibrous root, which 
generally runs into the ground, whereas the foregoing 
Iometimes grows upon trees. Native of Jamaica. 
7. Afplenium lanceum, or lance-leaved fpleenwort : 
fronds fimple elliptic entire fmooth, ftipe round fcaly. 
Native of Japan. 
8. Afplenium bifolium, or double-leaved fpleenwort: 
fronds pinnate; leaflets lanceolate fubfinuate connate. Root 
compo'fed of many thickifh branching black fibres; fronds 
all double, or conipofed of two equal fimilar leaflets uni¬ 
ted at the bafe by a common membrane. Native of South 
America. 
11. Frond pinnatifid. 9. Afplenium ceterach, or com¬ 
mon fpleenwort or miltwafte : fronds pinnatifid; lobes al¬ 
ternate confluent obtufe. The root confifts of many fibres 
adhering to a fhort fhapelefs head, which is furrounded 
thickly by the flumps of decayed leaves, and is of a dark- 
brown colour. Fronds many, from three to fix inches in 
length, the hollows between the lobes nearly of the fame 
fize and fhape as the lobes themfelves : there are about 
twenty pairs of thefe lobes in a frond; they are fhort, 
broad, roundifli, entire, but waved on the edge, larged in 
the middle of the frond, diminifhing gradually both to the 
end and the bafe; they are of a dark fhining green on the 
upper fide; and when the plant is old the edges are rolled 
backwards. The flipe is fhort and brown. Linnaeus re¬ 
marks, that the leaves are fo fcaly underneath, that the 
fructifications are not diflinguifhable; but this is only when 
tire fronds are old, and is occafioned by the involucres of 
the fradtification being very large : for when they are young 
the lines are fufflciently didinft; they are three or four, and 
Iometimes five, fix, and eveir feven, in number, placed ob¬ 
liquely near the midrib on each fide ; at firfi they are pale- 
coloured; but, as the plant advances in growth, the feed- 
vefTels enlarge, turn brown, and when they burft run to¬ 
gether, and cover the whole lower difk. Native of mod 
parts of Europe, on old walls and in the clefts of moid 
rocks ; as about Bridol, Bury in Suffolk, Heydon in Nor¬ 
folk, A the,ridge in Hertfordfhire, near Malham Tarn, and 
many other places in the northern countries. It is in feed 
from May to October. It has been recommended as a pec¬ 
toral, and as an aperient in obdructions of the vifcera : 
and an infufion of the leaves has been given againft the 
gravel. It was recommended by the ancients for the va¬ 
rious diforders of the fpleen, but it is entirely a ftranger to 
modern practice. 
10. Afplenium obtufifolium, or blunt-leaved fpleen¬ 
wort : fronds fubpinnate; pinnas obtufe linuate, decur- 
tent, alternate. Native of South America. 
III. Frond pinnate, x 1. Afplenium nodofum, or knot- 
ted-flalked fpleenwort; fronds pinnate; pinnas oppolite 
lanceolate and quite entire. Height a foot and a halt, 
(Browne fays three or four feet,) upright, fmooth. Na¬

12. Afplenium falicifolium, or willow-leaved fpleen¬

fronds pinnate ; pinnas roundifh crcnate. Roots fmall,

lanceolate. The leaflets vary fometimes in figure, and 
manner of notching about the edge. Native of Europe, 
in the crevices of rocks and walls, and in fhady places 
.£mong fiones. It is in feed from May to OClober. The

country people fometimes give a tea or fyrup of it for 
coughs and other complaints of the thorax. A little of 
the fyrup mixed with water makes a very pleafant draught. 
That which is brought from abroad has orange-flower wa¬ 
ter in it. But feveral different ferns are made ufe of for 
fyrup of capillaire. 
14. Afplenium viride, or green fpleenw ort : fronds pin¬ 
nate ; pinnas roundifli crenate truncate at the bafe. The 
ftipe of this is more tender, and frequently of a pa!o green 
colour, but fometimes brownifh towards the root; in fomc 
fpecimens they are brown and glofly, as in the foregoing. 
Native of moift rocks on the mountains of Yorklhire, Wefl- 
moreland, and North Wales. 
15. Afplenium ebeneum, or ivory-fliped fpleenwort: 
frond pinnate ; pinnas lanceolate fubialcate ferrate eared 
at the bale, flipe very glofly fimple. Native of North 
America. 
16. Afplenium dentatum, or tooth-leaved fpleenwort:

ginate. Native of South America and the Weft Indies. 
17. Afplenium marinum, or fea maidenhair or fpleen¬ 
wort, or dwarf fea-fern : frond pinnate ; pinnas obovate 
ferrate gibbous above, obtufe, wedged at the bafe. Sea 
fpleenwort has fronds from three inches to a foot in length, 
but commonly about five or fix inches. Stipes fmooth, 
generally reddifli brown. Native of SufTex, Devonfhire, 
Cornwall, Cumberland, Lancafhire, Scotland, and Wales, 
on rocks of the fea coaft. 
x8. Afplenium cultrifolium, or fickle-leaved fpleen¬ 
wort : fronds pinnate; pinnas fickle-lanceolate, gafh-fer- 
rate, from the bafe downwards angular. Native of the 
ifland of Martinico. 
19. Afplenium rhizophorum: fronds pinnate, rooting 
at top ; pinnas ovate repand fomewhat eared ; very fmall 
ones remote quite entire. This feldom grow<s above ten 
or twelve inches in length, and is always found with the 
top bending towards the ground. The young plant is 
Amply pinnate, but when farther advanced it is bipimjate. 
Native of Jamaica. 
20. Afplenium monantbemum, or one-flowered fpleen¬ 
wort : fronds pinnate ; pinnas trapeziumed obtufe ferrate, 
entire behind; one line'of frudification. Fronds nume¬ 
rous, attending, a foot high, frequently twilled, linear- 
lanceolate, acute, very fmooth. Native of the Cape of 
Good Hope. 
21. Afplenium ruta muraria, or wall-rue, tentwort, or 
white fpleenwort: fronds alternately decompound ; leaf¬ 
lets wedge-fliaped crenulate. Fronds many from one root, 
three or four inches high, furnifhed at the end with three 
(fometimes only two) pinnas, placed alternately ; they are 
fhort, broad, either rhomboidal or trapezium fhaped, very 
dark green above, paler underneath ; the two tides next 
the bafe entire, the two others finely crenate. The fructi¬ 
fications firfi appear in two or three longifh white oblique 
dots on each fide the nerve ; when the feeds are ripe the 
veffels burft, and cover the whole dilk of the frond except 
the edge. Native of Europe, in the fi flu res of walls and 
rocks. In feed from June to October. This alfo was for¬ 
merly ufed in coughs and obflruCtions, but is now entirely 
out of repute. 
22. Afplenium alternifolium, or alternate-leaved fpleen¬ 
wort : fronds limply pinnate; leaflets alternate, wedge- 
fliaped, gaflied above. This differs from our common 
wall-rue in having the Items more fimple, black at the 
bafe, with one or two fhort divilions only, having three 
leaves lobed and two-lobed ; the other leaves are foiitary, 
the firfi cut with four toothlets at mod; the tipper ones 
fimple, with the tip fliortly cut. In the lower part of the 
leaf are two or three lines, feldom four, of a longifh form. 
Emnxus pei fitted in regarding this as a variety only of the 
fpregoing. Native of Switzerland and Audria. 
23. Afplenium adiantum nigrum, or black maidenhair; 
fronds fubtripinnate, leaflets alternate, pinnas lanceolate
